Make something people want. Backed by AI Grant.
About the role
Y Combinator is building a new generation of products for the AI-native era — and we're hiring product engineers to build them. Some ship in the open to hundreds of thousands of developers ( gstack , gbrain — already north of 130,000 GitHub stars between them). Some are proprietary products in their own right ( Paxel ). All of them start from the same belief: a single builder with the right tooling now ships like a team of twenty, and we intend to build the tools — and the platforms — that prove it.
What they're looking for
- Experience shipping full-stack or systems software end-to-end
- Strong system design and independent decision-making
- Strong product sense and comfort designing user experiences
- Clear communication and the ability to work directly with non-technical stakeholders
- High judgment and integrity

This is a rare seat. You won't be maintaining someone else's roadmap. You'll be taking new products from zero to one, owning them end-to-end, and putting them in front of real users fast.
- Take new products from 0→1 — design, build, and ship full-stack systems and developer tools end-to-end
- Build AI-native software: agent orchestration, semantic search, embeddings, knowledge graphs, LLM workflows
- Own developer and user experience completely — 30-second installs, time-to-first-value measured in minutes, interfaces people actually want to use
- Ship some work in the open and engage a real community; ship other work as commercial product. Pick the right call for each
- Use your own...
