Gooseworks, a YC W23 startup, is looking for a Founding Builder—an engineer who loves building products, not just systems.

The company tackles distribution, the hardest problem for consumer brands, by building self‑improving AI agents that run growth end‑to‑end. In a few months, it has attracted 200+ paying users and generated 30,000+ ad creatives. Gooseworks is run entirely on agent harnesses and is based in San Francisco.

The role involves owning product and engineering decisions, shipping new features, and working closely with users. Candidates should have deep technical chops, experience launching real products, and a strong product/design sense. The stack is TypeScript/Next.js, Express, Prisma, Postgres, React, Tailwind, Claude Agent SDK, and Trigger.dev.

If you’ve shipped something with real taste recently, send the link. Goose’s AI creative engine turns brand assets into a continuous stream of on‑brand video ads, learning from performance data and human feedback to improve each month.
