Founding Product Engineer

Turn the AI runtime into product. Design and ship full vertical experiences — Search, Shop, Finance, Health, Legal — end to end on the shared Next.js + FastAPI stack.

What you'll do

  • Own a vertical product from schema to API to UI to launch
  • Design pure-white, pixel-perfect interfaces that ship the same day
  • Wire AI engines into product through the engine-registry pattern
  • Talk to users every week and move the metric you're hired to move
  • Set the product-engineering bar for the next ten people we hire

What you bring

  • 5+ years shipping consumer or prosumer software end-to-end
  • Excellent TypeScript / React / Next.js plus enough backend to ship without help
  • Strong design sense — you see the 1px offsets and the unclear copy
  • History of owning a product surface and the metric attached to it

Nice to have

  • Has launched a 0→1 product to public users
  • Comfort with Tailwind, design systems, and shipping copy yourself
  • Background working closely with founders or as a founder

Compensation

Founding-level equity plus competitive cash. Calibrated on first call.
