Minimal AI (YC S25)
Founding Engineer (Backend + AI-Focused Full-Stack Developer)
Minimal AI (YC S25), New York, New York, us, 10261
We're building AI agents that resolve customer support tickets for e-commerce businesses autonomously end-to-end. They cancel orders, issue refunds, check inventory, talk to suppliers, and get better over time.
To make this scalable, we're building an AI Manager: a higher-level agent that trains, monitors, and optimizes the Support Agents with minimal human input – effectively an AI-run support team. We're a YC-backed company.
Job Description We're looking for a backend + AI focused full stack engineer. The ideal candidate leans towards 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
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
Frontend: TypeScript, React, Next.js
