You lean toward systems, AI infrastructure, and reliability. You’ll build the agent runtime, evals, and integration layer that let us scale.\ \ What you’ll do

  • Ship production features across the stack
  • Work in tight loops: build → test → measure → refine
  • Use AI tools daily (Cursor, Claude, etc.) and push them further; automate glue work, generate scaffolds, build evals, multiply your own output
  • Take ownership of outcomes, not tickets

What We’re Looking For

We don’t care about years of experience. We care that you can build.\ You might be a fit if:

  • You can own features end-to-end and enjoy doing so
  • You ship fast and care about quality, clean architecture, solid tests, good UI
  • You’re resourceful and persistent, you figure things out
  • You’ve built things you’re proud of (products, open source, side projects)
  • You use AI tools daily and want to keep raising that bar
  • You think in systems and multipliers, not just tasks

Stack

  • Backend: Python, FastAPI, AWS
  • Frontend: TypeScript, React, Next.js
