YC itself hires software engineers from time to time. Many people don't know that YC has a small but very important software team. We run several websites - not just this one, but also workatastartup.com (the main way YC companies hire), a social network for YC founders, and the core infrastructure that YC itself runs on.
Recently, we've been spending most of our time building our own AI agents. Over the last year, YC has mostly funded AI agent companies, so it's been cool to go really deep building our own AI agents too. We're building agents to automate every aspect of what we do, and pushing the limits of what's possible with the current models to do it.
An unusual aspect of being on the YC software team is that you'll get full access to the YC program, founders and partners. The YC batch runs in the same building we work out of, so there are talks with famous founders happening most nights, right downstairs in our building. If you want to start a startup someday, working at YC would be an excellent jumping off point - several YC companies have come from team members who decided to start their own company.
YC works fully in-person in SF. We're happy to help you move here if you're in the US already. Unfortunately we can't sponsor new visas, but we're happy to transfer existing ones.
YC offers highly competitive compensation and benefits.

We’re ~3y old, ~35 people, have strong revenue, several years of runway, and great customers (including OpenAI, Anthropic, and Cloudflare). We’re backed by Sequoia & a16z.
As one of our first 30 engineers, you’ll get autonomy to build great products, skilled peers, opportunity for tremendous impact, and competitive salary, benefits, and equity.
We’re looking for exceptionally productive, thoughtful, tasteful, and kind people with a passion for making software development better for everyone.

I'm the cofounder & CTO of Krea (https://www.krea.ai).
We are a startup in San Francisco building browser-based AI creative tools to improve the workflows of artists, designers, and professional creatives.
Small team (~20); millions of active users; and raised over $83M from top Silicon Valley investment firms.
We're looking for talented engineers who want to tackle hard technical challenges with smart people while building a creative platform that big companies and startups will rely on.
The job:
- Build distributed systems to process massive (billions of files, petabytes), amounts of image, video, and 3D data, solving scaling bottlenecks as you go.
- Build data pipelines and deploy ML models to make sense of raw data (e.g. find clean scenes within videos).
- Learn ML engineering from world-class researchers on a small tight-knit team. As you’re building data pipelines, you’ll contribute to foundation image, video, and world models from 0 → production, and see them used by millions of Krea users.
- Play with massive amounts of compute on huge Kubernetes GPU clusters; our main GPU cluster takes up an entire datacenter from our provider.
Tech stack: python, pytorch, k8s, a rotating cast of data tools (e.g. DuckDB, massive relational DBs, PyArrow, etc.)
You should apply if you are an excellent generalist engineer with strong backend experience and an intuition for systems design. Bonus points for deep experience with distributed systems, kubernetes, and existing ML or data experience (but not required!). Cool side projects are a green flag.

Healthcare in the U.S. is a mess. Komodo Health is fixing that—with data. We’ve mapped the patient journey across the country to build the most complete picture of disease burden and treatment gaps. Our customers are pharma, payers, and health systems who actually want to do something meaningful with that information.
We have an exciting product, marmot, that is AI-native, both in the interface as well as in development, and want to carefully grow high productivity teams around this offering. AI integrated with Komodo's data is giving some of the most unique, real world insights any of us has seen come out of the new LLM era. Our product was just featured on Times Sqaure too! https://www.linkedin.com/posts/komodo-health_last-week-our-d...
We are looking for highly independent individuals, who can work in a new, small, but empowered team. What will you be bringing? - Proven experience working on Agentic systems that solve real problems OR Some evidence you have the "instinct" Andrew Ng mentions as the differentiators of successful Agent builders. We also take full ownership of the product, so experience+readiness for fullstack development is a must. Core ML experience is not required and for this position, not relevant at all. The new LLM/Agent era is... different.
Perks will include annual conference trip, periodic travel to SF/NY for on-site, Executive Coaching, etc.

It’s a shame that we have unbelievably good hardware like collaborative robots (cobots) that could transform warehouses and yet they still struggle with basic tasks like unloading mixed pallets. Why? Because today's software can't handle real-world chaos.
That's where we come in. At ko-br, we're building the AI brains that make robots truly adaptable. Our physical AI models tackle messy, unstructured problems starting with depalletizing of mixed boxes in dynamic warehouses. Think real-time adaptation to shifting pallets, mixed SKUs, and unexpected failures.
We're a deep tech startup at the crossroads of AI, robotics, and human-machine interface. While warehouses are our first battlefield, our core mission is physical AI. So you need to be comfortable with the idea of pivoting to other sectors like education (ex: building robots for schools and universities).

About me: Ex-Amazon/Meta, 2x founder (agritech & gaming). Built ML models and infra for everything from satellite imagery to nanotech, powered Alexa's vision, and led ML for WhatsApp.
San Francisco (Dogpatch) | On-site w/ flexibility | Full-time | Multiple Roles, $120k–220k + equity + benefits
Why: Comms are contested. Radios make you a target, satellites aren’t guaranteed, and brittle legacy networks won’t survive future fights.
What: We’re building an autonomous maritime network — think distributed systems in the ocean—extending resilient comms, sensing and compute to the edge in high-threat remote environments.
Who we are looking for:
- Software Engineers: large-scale distributed systems, networking, system design, embedded software, DevOps rollouts. Python, C++, Rust. Bonus: SDR, mesh, security.
- Electrical Engineers: PCB layout, embedded, RF, circuits, power/batteries, electro-mechanical. Bonus: DSP.
- Marine/Mechanical Engineers: pressure vessels, subsea robotics, gliders, ruggedized design; DFM, reliability, field deployment.
You will: ship code to robots, test on the water, move fast, own big surface area, and work directly with military operators.
About Us: Our founding team includes a Navy SEAL veteran, defense industry engineers, builders, hackers, and watermen (sailors, boaters, divers, fishermen). We’re focused on real future missions — not legacy requirements. Venture-backed; public launch soon.
Eligibility for a TS/SCI security clearance is a plus. Please send a short note + resume/portfolio to jobs@reveredefense.co with subject HN – Engineering.
