Founding Engineer: Backend + AI-Focused Full-Stack Developer

Minimal AI (YC S25) ‱ 🌐 In Person

In Person Posted 4 days, 5 hours ago

Job Description

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
