Founding Engineer: Backend + AI-Focused Full-Stack Developer (NYC)

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
