Estuary | US-Based / Remote | Full-time – https://estuary.dev/

Estuary is a VC-backed, post–Series A startup powering right-time data replication and transform — from sub-second CDC replication to terabyte-scale OLAP data flows.

We’re open-source, developer-first, and focused on making data movement radically simpler across both our Platform and Applications layers.

We’re hiring for:

Schema Labs (OpenCouncil) | Civic Tech Software Engineer | Athens, Greece | Hybrid (3 days in office) | €55K-65K

We're a 4-person non-profit building OpenCouncil (https://opencouncil.gr), an AI platform that makes Greek municipal council meetings accessible to citizens. We take hours-long council sessions and turn them into searchable, per-topic video clips, SMS/email notifications, and speaker analytics.

We're live with 10 municipalities including Athens, and the project is open source: https://github.com/schemalabz/opencouncil

Stack: TypeScript, Next.js, React, PostgreSQL, Elasticsearch. Heavy use of LLMs for transcription, speaker ID, and turning unstructured PDFs/transcripts into structured data. We use Claude Code, Cursor, and similar tools daily.

Sentinel Defense Technologies | Remote (Global) | Equity → Pre-Seed in 6-10 Weeks

We are building an AI-powered civilian protection platform — real-time threat intelligence for non-combatants in conflict zones. Think Waze for airstrikes. Multi-model AI pipeline (Gemini) ingests OSINT, verifies it through gated analysis, and pushes geolocated alerts to offline-first mobile clients. People die when information is late or wrong — we are solving both problems.

We are currently unfunded, operating on sweat equity. Pre-seed is 6-10 weeks out. This is not a side project — we have a working system, a pipeline of 39 vetted applicants, and a founder who has been shipping code daily for months. But I will not sugarcoat it: right now, this is nights-and-weekends until funding closes.

*We need two people:*

*1. Systems Architect / Full Stack Dev* You see the whole board. You think in pipelines, failure modes, and deployment constraints — not just endpoints. You will own the technical architecture of a system where a bug isn't a bad UX, it's a missed warning. Python/Django, MongoDB, LLMs (Gemini/Vertex AI). Bonus: Flutter, OSINT, geospatial.

*2. Implementation Partner / Full Stack Dev* You ship. Relentlessly. You take a spec and it's done by morning. You don't wait for perfect — you build, test, push, iterate. Same stack: Python/Django, MongoDB. You will be the person who turns architecture into working product at startup speed.

Both roles require exceptional drive. This is a founding team — not a job listing.

*Compensation (No BS):* - *Now:* Sweat equity only. You're building your stake. - *Pre-Seed (6-10 weeks):* $3,000/month + equity per contributor. - *Seed (6-12 months):* 75% market salary + equity. Increases from there.

If you need full salary today, this is not for you. If you want to build something that actually matters and you're willing to bet on yourself for 6-10 weeks to get there — keep reading.

*Stack:* Python, Django 4.1, MongoDB, Flutter, Vertex AI (Gemini), Docker, AWS.

*Apply:* PeterJFrancoIII@gmail.com — Send your resume or GitHub and tell me what you'd ship in your first week.

Apple | Software Engineer - Developer Tools/LLDB | London, UK | ONSITE (3 days/week in office)

The LLDB team is hiring an engineer to work on the debugger, which is used internally across Apple and externally by millions of developers. You'll drive features and improvements in LLDB, collaborating across teams working on the OS and toolchain. Responsibilities range from supporting new hardware and platforms to developing debugging features, with most work open-source (llvm.org & swift.org).

https://jobs.apple.com/en-gb/details/200643284/debugger-engi...

This is weird but I am required to create an Apple account to apply for this job. And I cannot create an Apple account, I just end up at an unhelpful page which says that this task cannot be done at the moment. I've tried tons of alternatives, but nada. It seems like the only way to 'recover' my account (I don't wanna recover!) is to do so from an Apple device, which I don't own!

Di Rezze Family Office | AI-Native Technical Operations Lead | Miami, FL (ONSITE) | $130K-$200K + Early Equity | Full-Time

We're building an AI-native clinical data platform from the ground up, not a legacy system with AI bolted on. AI is core to the architecture, the development workflow, and the product itself. Fully funded by a private family office, no outside capital needed, no fundraising runway concerns. We're assembling the founding team now.

We're building a founding team to revolutionize healthcare in the United States, and we're hiring a technical operations lead. Best analogy: studio engineer to a recording artist. You own the environment so engineering leadership stays on high-leverage product work. That means CI/CD, QA, testing infrastructure, compliance documentation, and 30-40% independent feature development. Ground-floor equity in a company that's pre-revenue by choice, not by circumstance.

Hard requirement: you are already shipping software with AI coding tools daily (Claude Code, Cursor, Copilot, or similar). Not curious about AI. Not experimenting. Actively building and deploying with it. If you can't show us something you built with AI tools in the last 60 days, this isn't the right fit. Stack: React/Next.js, Python, PostgreSQL, Docker, AWS. But we care more about polyglot instincts than any single framework.

What we're looking for:

3-7 years full-stack experience Strong QA discipline (you write tests because you want to, not because someone made you) DevOps comfort: Docker, CI/CD pipelines, cloud infrastructure Self-directed. We don't micromanage and don't plan to start. Must be US-based or already have US work authorization. We do not sponsor visas.

What you get:

Meaningful early-stage equity (not a token option grant)

Direct access to founders and decision-makers, no layers

A say in the technical architecture from day one

Relocation to Miami fully covered

Health, dental, vision

Interview process: 15-min screen (show us your AI-built work) > take-home exercise > 2-hour paid working session > culture fit conversation.

Email: jpd@direzzefamilyoffice.com, subject line "HN March 2026" so I can find you.

Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US only)

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

Softmax | softmax.com | San Francisco (onsite) | Full-time

THE MOST IMPORTANT UNSOLVED PROBLEM IN AI IS THE MOST POWERFUL OF ALL CAPABILITIES: ALIGNMENT.

Hi, I'm Emmett. You may know me as the founder of Twitch (YC S05), and as the (extremely) interim CEO of OpenAI.

I believe the question of how AI systems learn to understand themselves and others is one of the most consequential technical problems of our time. If we get it right, the agents we build today will become our friends and collaborators tomorrow. And the infrastructure required to train agents that are good at working in teams and societies will be extraordinarily valuable.

Softmax is building large-scale multi-agent, multi-policy environments that will benchmark AI agents – both our own and others – on their capacity for theory of mind, adaptive goal setting, and teamwork. We’re looking for the engineers who will make that possible.

The work is unusually hard. The problems are ambiguous and challenging. High autonomy, high expectations. You'll work directly with me and the rest of our small but mighty team.

If this sounds exciting, I’m looking forward to meeting you. E

$125K–$150K + meaningful equity. Reach out to me at jnapoli+hn@cvector.com

We’re a start-up company, we are building a local-AI camera OS that replaces cloud CCTV: SigmaStar cameras → RTSP/ONVIF → HDMI node → on-device AI (offline-first).

1. Hiring: OS / Device Lifecycle Engineer (Secure Boot / OTA / Identity) (Remote, UK/EU preferred)

We already run RTSP + inference. Now we need the person who owns several year device reality.

You will own (single layer ownership): Secure boot / trust chain (ROM → U-Boot → kernel → rootfs) OTA updates + rollback strategy (A/B, recovery modes) Device identity & lifecycle (provisioning, key rotation) Failure recovery (power loss, corrupted SD, watchdogs)

You must be able to answer directly: SD vs eMMC vs NVMe tradeoffs + corruption mitigation Brown-out behavior, thermal throttling, BSP maturity Camera ISP/NPU concurrency constraints + vendor SDK realities

2. Hiring: Independent Embedded/Firmware Engineer (Bring-up Audit & Stability) (Remote UK/EU preferred)

We’re shipping on real hardware. Reliability beats elegance. We need a senior embedded engineer to audit and validate our assumptions and prevent single-point-of-failure risk.

You will own: Independent review of firmware/bring-up assumptions Validation of performance, thermals, power behavior, stability Reproducible test plans (what breaks, how to detect, how to recover) Documentation that prevents knowledge living in one head

If you’ve shipped embedded systems that survive ugly reality (packet loss, unplugging, thermal throttling, storage corruption), we want to talk.

Competitive salary, flexible working environment & location, if you are interested, feel free to email: ayeeye.careers@gmail.com (subject: “HN – Role”)

What do y'all think about the latency/quality tradeoff with LLMs?

Human voices don't take 30 seconds to think, retrieve, research, and summarize a high quality answer. Humans are calibrated in their knowledge, they know what they understand and what they don't. They can converse in real time without bullshitting.

Frontier real time-ish LLM generated voice systems are still plagued by 2024 era LLM nonsense, like the inability to count Rs in strawberry. [1]

I'd personally love a voice interface that, constrained by the technology of today, takes the latency hit to deliver quality.

[1] https://www.instagram.com/reel/DTYBpa7AHSJ/?igsh=MzRlODBiNWF...

Not affiliated with Sesame, but this is what the realtime models are trying to solve. If you look at NVIDIA’s PersonaPlex release [0], it uses a duplex architecture. It’s based on Moshi [1], which aims to address this problem by allowing the model to listen and generate audio at the same time.

Lead Full-Stack Engineer Marker Learning | Remote (U.S. only) | Full-time | Engineering | 185-250k

I have dyslexia. I was one of the lucky ones. Diagnosed at eight, I got accommodations and support before things spiraled.

Most kids aren't so lucky. The path from initial concern to diagnosis can take years and cost families upward of $5,000. For many, it never comes at all. In one study, 50% of prisoners were found to be dyslexic, with 80% functionally illiterate. Behind every missed diagnosis is a kid who gets told they're lazy, when the reality is no one ever gave them the right test.

Marker Learning is building an AI-enhanced assessment platform that makes identifying learning differences faster, cheaper, and more equitable, especially for multilingual students who are routinely misidentified or overlooked. Imagine if every kid could be screened for learning differences as easily as they're screened for vision. That's what we're building.

This isn't a chatbot or a homework helper. We're a Series B company backed by Reach Capital, Andreessen Horowitz, and Primary, running a multi-million-dollar longitudinal study spanning K–12 and developing the psychometric engine behind it. We need engineers who are excited by that.

We're hiring a hands-on full-stack engineer (React, Node.js, TypeScript) to help build and scale the platform: adaptive testing infrastructure, AI-powered scoring scoring and data pipelines, and the systems that maintain clinical rigor at scale. High autonomy, lightweight process, fast-paced. 8–10+ years, ideally with 0-to-1 or early-stage experience. You'll work directly with psychometrics, product, and data science, and the engineering decisions you make now will define the platform for years.

Reach out directly with your resume and why you want this position to lucie@markerlearning.com. Make the subject "Lead Engineer Application (I am not a bot)".

Zo Computer | Systems Engineer, Product Engineer | NYC or SF | Full-time

Imagine having an entire software company working just for you – housing all your personal data, proactively working in the background doing chores, building apps, and organizing information to support your life. It'll work around the clock, interact with people and businesses to make you more organized, capable, and creative.

We're building a new category of personal computing device – a personal cloud, built for personal agents (and the agentic internet to come). Our mission is to make private cloud computing accessible to everyone, by designing enduring abstractions and flexible infrastructure for consumers and their agents.

Systems Engineer: You should be proficient in Python, TypeScript, IaC, etc. and be an expert in distributed systems, storage/databases, networking, and containerization.

Product Engineer: You must be a generalist, and should be proficient in Python, TypeScript, coding with AI, and building AI products. You must have great taste in system, API, and UX design. You must have operating experience in early-stage startups. Former founders are preferred.

  - Languages: Primarily Python, JS, C, and C++.
  - Hard Problems: Real-time constraints, custom networking protocols, and high-reliability systems that have to run 24/7 in public spaces.

  - 10+ years of experience. We need a "tinkerer" who understands math/physics and isn't afraid to poke at hardware.
  - Someone who thrives on "mission-critical" pressure. When a sculpture goes up in a public plaza, it has to work.
  - Mentorship-minded. You’ll help shape the software culture as we grow.

Apex Dental Partners | Full-Stack Developer | Dallas, TX (Remote US or Hybrid) | apexdp.com

We're a Dental Support Organization running 59 practices across TX/OK/CO/MO/IA/NE/TN/AZ. The unsexy industry description hides what's actually an interesting technical role: a small dev team with real ownership, pushing hard on automation and AI to make dental operations actually work well.

Stack is primarily Rails 7.1 (Hotwire+Stimulus.js), with some React/Electron, C# .NET (OpenDental), and Go — all on AWS.

You'd be joining a tight team where developers own problems end-to-end: from understanding why a billing workflow breaks down, to designing the fix, to shipping it. The domain is surprisingly broad — patient communication, PMS integration, payroll, clinical workflows — and there's no shortage of genuinely novel problems once you learn the business.

Good fit if you like: stable company, small team, broad latitude, and work that visibly matters to the people using it. Not a fit if you need a large eng org — but there's plenty of greenfield work as we're still actively building new features, not just maintaining legacy code.

Deep Systems | Senior DevOps Engineer | Remote EMEA, APAC, and Americas | Full-time

UTC-3 seems like a weird limit. UTC-2 and UTC-3 are basically just ocean. So the only real places that qualify are Buenos Aires and Coastal Brazil.

Also, not sure what the point of requiring that even is. There are plenty of candidates that would be willing to work those time ranges on the periphery. It's no different than getting an evening/graveyard shift at a domestic company, after all.

Hey, I would love to get into this position. Right now at my master's thesis I am researching something similar to this. I've just applied! Thanks for sharing the position.

Are you open to UTC -5?

Osaurus | Full-Time | Remote | Protocol Engineer

Osaurus is a native macOS AI platform. The core idea: inference is a commodity — everything else (context, memory, tools) should be owned by you, locally. Think of it as the runtime layer for AI on Mac that works with any provider (OpenAI, Anthropic, xAI, local models via MLX).

3.7K+ GitHub stars and 54K+ downloads with zero marketing spend. Open source, local-first, provider-agnostic.

Looking for a protocol engineer who wants to build agent-to-agent networking and communication infrastructure. You'd be the first hire.

What we work with: Swift, macOS native APIs, Apple Silicon optimization, provider-agnostic API layer, plugin architecture. You don't need Swift experience specifically — strong systems fundamentals and the ability to pick things up fast matter more.

We're solving a number of hard technical problems that come with syncing hundreds of billions of rows of data every day with perfect data integrity: building reliable & scalable infrastructure, making data pipelines manageable without domain expertise, and creating a UX that abstracts out the underlying complexity to let the user share or receive data. We're powering this feature at companies like Stripe (Metronome), Gong, Iterable, and more.

FusionAuth | Senior Java Engineer, Technical Support Engineer, Account Executive , Solutions Engineer | Varies between REMOTE (in USA, also in Europe but only for the account exec/solutions engineer positions) and ONSITE in Denver, CO, USA, details in each job desc | Salary ranges listed on job req, but for the Senior Java Engineer it is 140k-180k

PS: If you're a pure DevOps person or a pure Data Engineer who wrangles data tools, please read the above requirements carefully before firing off an email. This role is an intersection of a lot of sub-roles, not a particular specialization

Fractional AI | Senior/Staff Software Engineer | SF, NY, NC, Dubai | Onsite

We’re a team of experienced generalist SWEs and AI enthusiasts who are building custom AI agents for enterprise clients. You’ll work on 3-4 different projects a year and play a central role on each one. No AI experience required: we are actively trying to be the best place in the world to learn applied AI.

I’m Frank, an engineer here. This is the first services-style company I’ve worked at, so for those of you in a similar boat, this is what I’ve really liked so far:

* The learning rate is super fast. 3-4 client projects a year, each with different tech stacks, products, industries, and architectures.

* Our projects are typically high priority and sponsored by prominent executives. The path here for projects to have real impact on usage or bottom line is much shorter.

* We’re “selling pickaxes during the gold rush”. When AI finds its next killer app, we’ll hopefully be the first to know about it.

We’re hiring SWEs onsite with offices in San Francisco, New York, Durham NC, and Dubai. Feel free to reach out to me directly (frank@fractional.ai) or take a look at the full job posting:

Backend Engineer: (looking for Kotlin/Java/Scala experience). You'll work across the backend: building enterprise integrations, large-scale scraping and parsing pipelines, and systems that let users apply LLMs to millions of documents to generate insights at scale.

AI Engineer: Applied AI plus strong software engineering. You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini. Expect hands-on Python, ML system design, experimentation, and production reliability. Bonus for RAG depth and frameworks like LangChain, LlamaIndex, or Hugging Face.

We're looking to build our in-person team in NYC but also open to remote!

Apply: https://starbridge.ai/careers and mention HackerNews or email recruiting@starbridge.ai with your resume.

We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.

Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.

If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...

You can find out more about the product we're building at https://spacelift.io and also see our engineering blog for a few technical blog posts of ours: https://spacelift.io/blog/engineering

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

We make robots that autonomously construct buildings. We are currently developing and manufacturing our autonomous bricklaying system in the beautiful centre of Amsterdam. And our robots are already earning real revenue operating on construction sites all over the Netherlands.

We're looking for experienced software engineers for many roles. You can help us solve problems like:

- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)

- Modelling buildings in code and finding the right UI for operators to edit them

- Designing systems for robots to drive safely and fully autonomously around a building site

Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium

We're rapidly scaling up operations and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

Constellation Finance | Multiple Engineering Roles | New York, NY | Hybrid | Full Time

At Constellation, we are building a future where technology is the lethal advantage in credit investing.

Credit documents govern everything from how much debt a company can incur, or pay in dividends, to what they can do with proceeds from selling assets. Hidden debt capacity, loosely drafted provisions, or ambiguous definitions can materially alter recovery, making precise covenant interpretation essential to investing outcomes.

Constellation makes it easy to read credit documents, calculate covenant capacity, and plan liability-management transactions, reducing the mechanical bottlenecks to analyzing credits and generating alpha.

Our team is comprised of subject matter experts who have spent a decade in credit (Goldman Sachs/Citadel), AI/ML researchers, and full-stack engineers who are dedicated to solving frontier problems in their application to the world's largest asset class.

We recently raised a $3.25mm round led by Haystack and Company Ventures. We are hiring for these roles: https://www.constellationfinance.ai/#/careers

SkySafe (https://skysafe.io) | Wireless Engineer (SDR) | San Diego, CA | ONSITE (Hybrid)

At SkySafe we build drone detection and tracking at scale.

I am looking for a Wireless Communications Engineer with SDR expertise to join my team - I'm the hiring manager.

I need someone with a very strong background in signal theory and experience building software wireless modems. You will spend time learning about new systems from our reverse engineers (no RE experience required!), implementing both open and recovered specifications, and refactoring existing modems code to improve it in both theory (ie - what is the algorithmic state of the art for demodulating xyz thing) and practice (ie - how much memory bandwidth and CPU are you using where). As such, I'm looking for someone with true software modem experience; while DSP, FPGA, and generated code experience are useful and relevant, you'll need to be able to read and write C++ directly.

I need someone who can come into the office in San Diego as needed to work with hardware, so this is a hybrid on-site role. This position requires access to technology which is controlled by US Export laws, so you also need to be an eligible US Person.

What we have to offer: $145-200k. Fun, small team dynamic. Work with experts in adjacent fields. Startup environment with good work-life balance and limited red tape. Rapid iteration and feedback in the wild. Good equipment at the office.

Apply: brian@ for a direct line, https://jobs.lever.co/skysafe for the formal route (we have some other roles I'm not the HM for listed there, too, if you're interested in the company!)

You will design delivery pipelines, build consent management workflows, architect Twilio integration layers, and handle the sharp edges that come with messaging at scale: retry logic, opt-out compliance (TCPA, A2P 10DLC), delivery optimization across carriers, and AI-driven message categorization.

You'll likely thrive here if you:

- Have 5+ years building and scaling backend systems - Are strong in Ruby on Rails and Javascript with solid SQL chops

- Enjoy owning complex features end-to-end, from design through production support

- Think in terms of edge cases, failure modes, and delivery guarantees

- Want to mentor other engineers and shape technical direction

- Care about building infrastructure that has direct impact on patient outcomes

RINSE | REMOTE or San Francisco, Los Angeles, Chicago, Boston, New York, New Jersey, Seattle, Austin, Toronto, or Washington DC | Software Engineer | Full-Time | Salary: $80k-$200k USD | https://www.rinse.com

Rinse provides dry cleaning and laundry delivery services to customers in twelve metropolitan areas in the US and Canada. We have sophisticated logistics optimization software, a polished consumer product, and firm business fundamentals. We're now over a decade old - this is a stable, yet consistently growing and innovating, company.

Our engineering team is distributed across the United States and internationally, and has been entirely remote for years now, but a desk can be provided in the above cities if you'd prefer.

We're open to both newly-graduated engineers or more senior engineers, provided they meet our bar. We're particularly interested in true full-stack engineers, with strong React / Typescript / CSS skills to complement comfort in a Python / Django environment. We're also seeking engineers with experience leveraging AI to automate complex operational processes.

We're particularly interested in someone with significant React Native expertise at the moment, as we work to improve the apps our customers, delivery valets, and partners use.

You will join a high-caliber team where collaboration, honesty, and open communication are at the core of everything we do.

Search term bingo: Logistics, Django, Python, Optimization, React, React Native, Postgres, Mobile Engineer, Automation, Delivery, OR-tools, Forecasting

Do you have offices in all those cities, or why are you listing them? I will downvote your and all other posts who do this unless you reply, because I think you are doing this to appear when people search for specific location.

We do have a physical footprint in each of those cities, and there is real value in being able to actually see our product and service in person by being in our service area. We can provide a desk with real co-workers in any of those cities.

See https://www.rinse.com/contact/#locations-heading

Most developers prefer to work from home, though! We're fully remote, and are free to mostly work from home or a co-working facility instead of one of our potentially-noisy offices.

Am I crazy if I hate remote?

I don't make the rules here, so I am going to remove the downvote, but I believe there should be a way to easily search for jobs that aren't remote.

I appreciate your response.

edit: I can't remove it anymore

We have paying enterprise customers and more demand than we can keep up with.

You'd be the first engineering hire. Agent orchestration, durable execution runtime, self-healing infra, most of the important architectural decisions haven't been made yet.

We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, and more.

This is an opportunity for builders and practitioners to help shape a deep-tech product from its earliest stage.

Spotlight roles:

* Engineering Lead

* Product Software Engineering (Quantitative Modeling)

Ongoing hiring:

* Bayesian Software Engineering

* Program Synthesis Engineering

We're also looking for Domain Experts to collaborate on high-value use cases -- identifying and validating opportunities, shaping them into working solutions with our engineers, and taking them from pilot to production with real users. Practitioners with expertise in Valuation Models, Quantitative Default-Probability Models, or Interest Rate Prediction Models are particularly relevant right now.

Neoteny AI | Founding Researcher | REMOTE (US East Coast/Europe) / ONSITE (London, NYC)

Neoteny AI is building the sovereign intelligence layer for code. We are a team of builders from Meta, AWS, and NYU who believe that the future of coding intelligence is not a generalist chatbot in the cloud, but a specialized, repository-aware model that lives inside the enterprise perimeter.

We are looking for a founding researcher to lead our core research agenda. You will work at the intersection of representation learning, program synthesis, and efficient inference.

You will figure out how to teach models the latent physics of a codebase, the implicit architectural rules, dependency patterns, and style constraints that generalist models miss. Your work will range from designing new data engines to experimenting with novel architectures that break the memory wall of current transformers.

We are looking for someone with deep ML expertise (PhD or equivalent) who is code-fluent and comfortable writing kernels, not just training scripts.

Comper | Software Engineer #2 (Frontend focus) | €80-110k + equity | Utrecht, The Netherlands | ONSITE | https://comper.io

We make software landscapes understandable and explorable. Our canvas is zoom-to-code, and shows data on overlays from all of the git repos in your company. LLMs go through the codebase and extract the architecture.

We provide clarity when it's most needed: re-orgs, onboarding, explaining the tech stack at board meetings. Or just being stuck in your IDE and want to ask your team mate a question. We'd like to do to large org codebases what Figma did to design.

Comper needs someone that can build revolutionary UIs and go where no man has gone before. Our UI is the core of our product: a zoomable canvas that has all your code, documentation and diagrams on it. We have a long way ahead and need serious thinking to make sure we explain the software stack as simple as can be.

I'm the founder & CTO. We just raised a pre-seed and are now with 6 people. Find the vacancies on our site and send us an email.

You: strong full-stack shipper, reliable teammate, comfortable with customer feedback.

krea.ai | Senior Backend Engineer | San Francisco, CA | ONSITE | https://www.krea.ai

krea does AI research & builds AI tools for image generation, video generation, node-based workflows, LoRA training, and more. Small, mostly in-person team with a view of Alcatraz from the office window. Our users range from hobbyists all the way to professional designers at Apple or architects at firms behind The World Trade Center or Burj Khalifa.

We're looking for senior backend engineers. You'd work across our SvelteKit app (Postgres, Redis, Docker, ClickHouse), Python ML inference on GPU clusters, and k8s clusters across multiple cloud and GPU providers.

Some recent projects:

- building canary deploys with cookie-sticky traffic splitting - implementing durable execution for long-running workflows - designing our public API with OpenAPI docs auto-generated from Zod schemas - implementing enterprise-grade authentication, authorization, and permissions - optimizing ML inference for our hosted image generation models

We care way more about first-principles and core engineering skills rather than specific shenanigans around programming languages or particular tooling—knowing a lot about old UNIX principles is a plus though.

You should be comfortable owning things end-to-end. Experience with GPU infra is a plus. Many of us have some kind of creative background, it helps when building tools for creatives but is not a requirement by any means.

To apply, email d+hn@krea.ai (use the +hn suffix to make sure your email is prioritized!)

Innolitics | Medical Device Engineers + Physician-Scientist (MD/PhD) | REMOTE (US) | Full-Time

Innolitics builds AI/ML software for medical devices — the kind that detects ear infections, tracks metastatic cancer, and plans radiation therapy. 60+ FDA clearances. We need engineers who want their work to matter. We're a remote-only firm (since 2012) that does engineering, regulatory, and cybersecurity under one roof. Our team includes MDs, PhDs, and software engineers. Clients range from Series A startups to large device companies. We're hiring for three roles:

1. Physician-Scientist (MD/PhD) — Biostatistics & AI Software Development MD + PhD in biostatistics, bioinformatics, epidemiology, or a related quantitative field. You'll design biostatistical plans for AI validation studies (MRMC, standalone, prospective), build production-grade statistical software and data pipelines, write FDA-facing statistical sections, and analyze large clinical imaging datasets. Fluent in Python and/or R. This is not a pure research role — you'll ship code that gets FDA-cleared and deployed in clinics.

2. Senior Web/Mobile Medical Device Engineer 5+ years SWE experience. 3+ years each in web and mobile. Fluent in TypeScript and Python. You'll build medical device software and produce FDA-facing technical documentation. Cross-functional role bridging engineering and regulatory teams.

3. Medical Device Software Engineer 3+ years SWE experience. Fluent in Python, C++, or TypeScript. Heavier emphasis on software development initially; you'll grow into regulatory documentation work over time. All roles involve writing production code for medical devices, authoring documentation for FDA submissions, and working directly with clients. No prior medical device experience required — we'll teach you. Why engineers stay here:

Agentic AI tools (Claude Code, etc.) are part of our workflow. We treat them as a impact multiplier, not a threat. ~1 hour of meetings/week for ICs. Flexible hours. 2 hours every Wednesday dedicated to learning ("10x Time"). Healthcare-only revenue. No debt. Never had a layoff. We pay $300 for take-home exercises because your time has value.

Stack: Python, TypeScript, C++, R, Django, React, TensorFlow, PyTorch, scikit-learn, Qt, Terraform.

Adobe | Staff Backend Engineer (Distributed Systems) | SF, SJ, NYC | Hybrid | Full-Time

Adobe is building a Real-Time Customer Data Platform (CDP) that operates at a scale most companies never see. We aren't just building another "enterprise app"; we are managing trillions of events and solving complex state problems in real-time.

If you find "distributed systems" a lifestyle rather than a buzzword, we want to talk. We are currently tackling challenges in high-throughput streaming, identity resolution at scale, and sub-millisecond data retrieval.

The Stack:

Core: Java, Scala, Spring Boot

Compute/Stream: Spark, Flink, K8s

Storage/Messaging: Kafka, FoundationDB, Aerospike, Cosmos DB, Delta Lake

Infrastructure: Multi-cloud (Azure/AWS), Docker, Vector DBs

What we’re looking for:

The "8+ Years" Profile: You’ve spent a decade breaking and fixing large-scale distributed systems.

Concurrency & Performance: You don’t just write code; you tune it. You understand the JVM, memory models, and how to squeeze performance out of every thread.

Architecture: Experience with Flink/Kafka/Spark isn't just about using the API—it's about knowing how they fail and how to keep them running under massive load.

The Logistics:

Locations: San Jose, New York, or San Francisco (Hybrid/Onsite).

Comp: $177,900 – $257,550 base + Equity + Adobe’s notoriously good benefits.

How to Apply: Email me directly at skatkar@adobe.com with "HN: [Your Name]" in the subject line.

SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.

We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.

We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.

Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.

We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Prior Labs | Berlin / Freiburg / NYC | ONSITE & REMOTE (EU) | Full-time

Tables power every clinical trial, financial model, and scientific experiment, but deep learning has mostly ignored them. No natural sequence, no spatial structure, no shared vocabulary across datasets. LLM architectures don't transfer. We built TabPFN, the first foundation model that actually understands tabular data (published in Nature, 3M+ downloads, new SOTA for tabular ML). The hardest problems are still open.

The model is half the product. The other half - training infrastructure, real-time serving, developer platform, reliability - is what turns a research breakthrough into something enterprises trust in production. We're hiring across both.

ML Engineer, Cloud Platform — Design and scale the core infrastructure for serving and finetuning foundation models in production. Early enough that you're making the architecture decisions, not inheriting them.

ML Engineer, Training Infrastructure — Own GPU infrastructure, distributed training performance, and the developer productivity layer (CI, experiment tracking, model registry) that keeps research moving fast.

Full Stack Engineer, ML Platform — Build the product that puts tabular foundation models in users' hands, from data upload through inference and results. You'll work across frontend, backend, and directly with the research team to turn new model capabilities into production features.

Research Engineer, Foundation Model — Design experiments, run ablations, build training infrastructure, contribute to papers. Research engineers here aren't supporting scientists — they are the science team.

Also hiring: Research Scientist, Applied Scientist, Forward Deployed ML Engineer, Developer Relations Engineer, AE, BDR.

20-person team selected from thousands applicants. Backgrounds from Jane Street, Google, CERN, G-Research. Led by Frank Hutter, advised by Yann LeCun and Bernhard Schölkopf. With backing from Balderton, XTX Ventures and leaders at Hugging Face, DeepMind, and Black Forest Labs. Comp competitive with top AI labs, meaningful equity.

Immunera | Principal Machine Learning Engineer | NYC area (hybrid) | Full-time | immunera.ai

Hey! I’m Maxim, cofounder/CEO of Immunera.

We're building blood tests that use gene sequencing and machine learning to help patients with autoimmune disease. Immunera spun out of years of research at Stanford, and our technology has been published in Science and covered by The New York Times.

We're hiring a Principal Machine Learning Engineer to shape the core models and infrastructure that power our blood tests. We are partnering with hospitals to generate training data from real patients for our language models and other biological sequence models.

This is a senior engineering role with significant autonomy at an early-stage, venture-backed startup. We're looking for strong experience building and operating ML systems in production (Python, PyTorch/TensorFlow, cloud platforms). Prior biology or healthcare experience is NOT required; we care much more about your ability to reason about data, models, and systems.

Transfyr | Full Stack Software Engineer | Cambridge, MA | Full-time | ONSITE

Transfyr is building physical AI for science.

Why is it that a professional athlete has dramatically more information about every play they make than a scientist has about the cause of any experimental failure? At Transfyr, we are building the infrastructure to make real-world scientific work legible, transferable, and reproducible.

Modern science is capable of extraordinary outcomes, but much of the most important insights never become explicit: how experiments are actually executed, protocols drift, how experts make gametime decisions on the fly, why experiments fail on Tuesdays. This tacit knowledge is rarely captured, making it difficult to reliably reproduce results, much less hand off protocols to new team members or collaborators. We believe our systematic failure to capture tacit knowledge is holding back the entire industry.

We’re building systems that operate directly in real laboratory environments to elucidate, capture, and interpret this missing information. Our platform records and analyzes multimodal data about how scientific work is performed and turns it into durable, operational knowledge. In doing so, we are also building the world’s largest commercial dataset on real-world scientific execution.

This foundation is critical not only for driving elite human performance today, but for enabling meaningful automation tomorrow. Physical AI systems cannot learn from outcomes alone; they require rich, grounded records of how work is actually done in the real world.

Key domains of expertise we’re looking for (hiring from entry level to senior leadership):

- Computer Vision: take messy real-world images and video and make sense of them

- AI / ML Research & Engineering: build the best digital brains to support the best physical brains on the planet

- Full Stack Engineering: integrate our AI and data into tools that solve real customer problems.

A change from when I posted here previously: we are now focused on on-site in-person roles, at our lab/office in Cambridge, MA. And, we are particularly interested in DevOps/backend experience for the full stack role.

If you're interested, apply here! https://transfyr.ai/join-us

focal | Head of Technology & Applied AI | Remote/Onsite/Hybrid (US)

focal is an institutionally-backed, next-generation venture firm. Currently investing out of fund II (2025 vintage), we lead at the start, often pre-incorporation, with up to $1M. The next great venture firm won't just use AI. It will be AI-native from the ground up - seeing sooner, deciding faster, and building systems that compound across every founder, deal, and outcome. That's how a 5-person team beats a 50-person firm. We're building that firm. You'll own how it gets built.

This is a long-term, high-impact founding role with meaningful financial upside (carry in funds) and ownership over how the firm is built. You'll join as our 5th team member and partner closely with our GPs in a flat structure.

Your core responsibility: Build and own the AI-native operating system that becomes our structural edge.

Why this might be interesting to you: you get carry in our funds, full ownership over architecture and roadmap, and a problem space that's genuinely unsolved. Venture firms haven't been technically reimagined in decades.

Who you are: A founder-type. A builder: Highly technical, deeply curious, high-output, high-agency. You move from idea → architecture → shipped - fast. You want real ownership over process and outcome, not a seat at someone else's table. You've built things from scratch that worked, and you can point to them.

Comp: carry in our funds (your upside is tied to fund returns), competitive cash, 100% healthcare, 401(k), 6 weeks PTO, 3 months parental leave, budget for compute/tools.

We're not asking for a resume. Send us your LinkedIn (and X if you have it) along with your favorite thing that you've built and tell us why you're proud of it. GitHub, side projects, demos, whatever.

Chestnut | Product Engineers (Backend / Full-Stack) | SF + Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut

Chestnut builds the systems insurance carriers actually run their distribution business on. We replace spreadsheets, legacy vendor systems, and manual processes with real-time data, deterministic workflows, and AI-assisted tooling.

This is end-to-end product engineering.

You won’t just write APIs. You’ll design schemas, build backend logic, ship UI, deploy to production, and handle the sharp edges that show up with real customers. The problems are messy and state-heavy: payouts that must reconcile with finance, onboarding flows with regulatory constraints, dynamic hierarchies, retries, chargebacks, partial failures.

We care a lot about correctness. These systems move real money and cannot drift.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS

We use AI heavily in our workflow — for drafting, refactoring, test generation, and exploring solutions. We expect engineers to use it aggressively. We also expect you to understand what it’s doing, spot when it’s wrong, and maintain strong fundamentals. Taste matters.

You’ll likely thrive here if you: - Have 3–6 years building real product systems - Are strong in at least one typed language and comfortable picking up others - Enjoy owning features end-to-end - Think in terms of invariants, edge cases, and failure modes - Like shipping quickly but cleanly - Want to build systems that operate in production, not demos

We’re a small, high-agency team. You’ll have meaningful ownership and direct impact on customers.

Hybrid in SF and Seattle.

Bubblehouse | Fully REMOTE | Full-Time | $200–250k | Principal Engineer

Bubblehouse is a fast-growing custom loyalty platform, tripling the revenue each year. Headquartered in NYC, the entire team is fully remote and spread across the globe. We power loyalty programs for brands like American Girl and Old Spice.

We’re expanding our lean team of extremely experienced developers. Companies are switching from other platforms thanks to the customizations and flexibility that we offer, enabled by our pace and technical excellence, which we intend to keep for years to come.

We run on Golang and use custom data storage on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap’ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.

Zero lines of React, almost zero third-party dependencies (carefully vetted), every line of JavaScript manually written with respect and understanding of the web platform. We render HTML server-side like it’s 2005.

Looking for:

1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.

2. Thinking and problem solving outside the box. (We don’t _always_ go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)

3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)

4. Broad experience across multiple programming paradigms, platforms and software stacks.

5. Demonstrated care for the software craftsmanship (which can take many forms).

6. Great spoken English, and ability to communicate 9am to noon in New York time zone.

We give you a literally fast-paced environment (with features delivered in days) where you need to solve very challenging problems with practical advanced technology, take on entrenched market leaders, and help entrepreneurs across small and large businesses delight their fans.

Send a plain text cover letter to andrey+hiring@bubblehouse.com. Help us see how you stand out. Summarize your experience. Link to 1–5 impressive things you’ve built and proud of, link to where we can see some of your code, include your portfolio/CV, describe the platforms and stacks you’re an expert in. How did you start programming? What are you most passionate about in technology? What are the most interesting or weird things you’ve done? What are your strongest held professional opinions? Please make your email easy to read, we’ll appreciate that.

(If you have applied before, no need to re-apply, we’ll reach out.)

exe.dev | Full time | SF Bay Area | multiple roles

Support Engineer - If you want to use Claude or Codex (or Shelley!) to trawl through our code base, augmented with (carefully scoped) API keys to make our customers lives better, we are hiring.

Designer - If you want to use Claude or Codex (or Shelley!) to make our product functional and beautiful, we are hiring. You do not ship mocks or assets to other teams. There is no other team. You ship by pushing to production. Don't worry, we've got your back.

We are a small team and going to stay one. The focus is building a high-trust environment. Success for us is if you say "I'm going to fix the load balancer" we all sigh with relief, because you are on it and we can rely on you to take on and solve large projects.

Empire Flippers | Remote (no office), all timezones | Full-time | https://empireflippers.com

Empire Flippers is a true global-remote company with travel in our DNA and employees scattered across 5 continents and all sorts of countries. Since I joined 6 years ago, I've personally been to India, the US, Brazil, Ecuador, Colombia, Mexico, the Philippines, China, Japan, Thailand, the UAE, all while working remotely and coding our Ruby on Rails + React app. More about us here: https://empireflippers.com/about-us

Though not as well known in the Hacker News / venture-backed startups sphere, Empire Flippers is widely considered the #1 marketplace for buying and selling online businesses in the 5 to 8 figure USD range.

Think of businesses like --- that recipe site you landed on as the first result when you googled "best chicken tikka masala recipe". Or the Amazon FBA seller whose product you purchased when shopping for "Widget XYZ" (with Amazon FBA, these ecommerce businesses never touch inventory and so it's a fully online business).

Turns out these type of businesses may be earning 10s of thousands of dollars per month in profit (or more!) and when the (often first time) founder is ready to sell, Empire Flippers is the #1 place to do it safely, securely and at a fair market price.

Before I joined Empire Flippers I only had a peripheral understanding of this space, but now that I've been steeped in this industry I can say that this "mini M&A" world is just as exciting as the high-flying unicorns (and decacorns) that we read about daily on Hacker News.

The company is hiring for a few different positions (both technical & non-technical), all of which can be found here: https://empireflippers.com/careers

But in particular, I'm hiring a Ruby on Rails developer to help me continue to build out new features in our Platform, both for customers and to help run our (very extensive) internal operations of vetting incoming businesses, facilitating their sale, and migrating them to the new owner after they've been purchased.

That job ad can be found here: https://empireflippers.com/career/ruby-on-rails-developer/

As mentioned, we are a global-remote company that hires people of all nationalities located in any country in the world.

Hope to see your application soon, and with any questions feel free to email me (Ben) at beng at empireflippers.com

> *US resident requirements: If you are in the US, we will accept candidates residing in Texas, Florida, Alaska, Pennsylvania or Colorado, as we are registered for payroll in these states. Otherwise, US candidates should plan to live abroad or have plans to relocate to one of these 5 states.

This is a bummer. Is it still accurate?

Founders: this is what an excellent job posting looks like. Well done.

Just fyi to others that in the "Details to Keep in Mind" section is a notice that US residents can only reside in Texas, Florida, Alaska, Pennsylvania or Colorado.

Looks like a cool job, but unfortunately I'm not in one of those states.

What kind of timeline can be expected to hear back on an application? I applied to one of the roles last month, and haven't heard anything at all.

which role? I can look into it for you and see what the hold up is.

It was the Senior CloudOps Engineer. Interestingly, I noticed that one wasn't listed on the general careers page, not sure if that might be a factor?

Nectar Social (https://www.nectarsocial.com) | Software Engineer, Product Designer, Product Manager | Palo Alto, CA | Onsite | Full-time

Hi HN. I am an Engineering Manager at Nectar Social, and we're hiring across product, design and engineering.

The traditional playbook of buying ads on social media platforms no longer works for most brands. Buyers make purchasing decisions from organic conversations on social media platforms like Instagram, Reddit, X, and LinkedIn. Nectar listens to conversations in real time, surfaces actionable insights, attributes engagement to revenue, and drives conversions.

We came out of stealth last year and we are on a fast growth trajectory working with brands like OLIPOP, Hatch, K18, and Little Spoon. The company is ~30 FTEs and has many interesting challenges:

1. We ingest data from major social media which brings scaling and performance problems

2. We run AI agents on the content which requires us to control cost and optimize quality

3. We need to present lots of information about social conversations in an understandable way which requires good design.

4. We need to build resilient systems that can work within the constraints of our third party dependencies.

Our tech stack is React, Typescript, AWS, Pulumi, Postgres, Clickhouse and Turbopuffer. We use AI tools thoughtfully to optimize our daily work - Cursor, Claude Code, Graphite, v0 / Replit, and Granola.

The roles we are hiring for:

- Staff Backend Engineer - https://jobs.ashbyhq.com/nectar-social/e5797dfd-275e-4a7a-b9...

- Staff Product Engineer - https://jobs.ashbyhq.com/nectar-social/2f942c62-bc21-41a2-ae...

- Senior Product Manager - https://jobs.ashbyhq.com/nectar-social/b63c6254-df3d-406e-83...

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security. We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome. We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team. Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.

We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

Kinelo | kinelo.com | Full-Stack Engineer (AI + Backend) | San Francisco | Onsite

Kinelo manages the new type of hybrid team that will emerge in the future: humans+AI working shoulder-to-“shoulder”.

Our first product helps human software engineering teams deliver more efficiently and more reliably by assisting in coordination and engineering management. But it’s built on a foundational layer that ingests data, knowledge, and process across communications and systems, exposing that to humans and AI alike.

Eventually, Kinelo will become a proper human+AI orchestration layer, managing entire companies, and our goal is to have Kinelo run Kinelo (we already dogfood it today).

We’re looking for high ownership individuals to join our small team and shape its direction. We also just opened a new SF office and new hires will have the ability to help shape company culture, engineering practices, architecture, and roadmap.

We’re well-funded (just raised another round), founded by a serial founder, anti-bureaucratic, and highly technical.

We’re looking for:

- Those who want to go 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product

- ~8 years professional experience, including the pre-LLM days with strong CS fundamentals

- A balance of wisdom from experience and optimism about the future

- Strong TypeScript and Postgres (or other RDBMS) experience at scale and with high reliability (SaaS apps, APIs, etc)

- Experience with a variety of technologies, including containerization, distributed systems, and at least one strongly typed programming language (Go, C++, Java, etc)

- Ideally experience with ML and AI systems (though expertise in ML, data science, etc is not needed for this role)

We can’t sponsor visas but relocation assistance to SF is possible.
