Founding Engineer
About this role
Superset (YC P26) is building a self-improving IDE for running coding agents in parallel — already used as a main IDE by tens of thousands of engineers at companies like Netflix, DoorDash, and Wix — and is hiring a Founding Engineer in San Francisco. The team is four people, including three ex-YC CTOs, and the work spans from the pty and stream transport layer up to the UI, all in TypeScript; you would own big features end to end and likely ship something in your first week. Compensation is $175K–$225K plus 1.0–1.5% equity. The interview process is fast: a 15-minute call, a 1-hour TypeScript round, a 1-hour system design round, then a week working with the team in SF — with a decision within 48 hours of each step.
