About the role

You'll work directly with the founders on the product itself: the chat interface, the model routing, the parts users touch every day. The stack is Next.js, TypeScript and MongoDB on Vercel, with Cloudflare for storage and edge. The bar is simple: if the rest of us disappeared, you could keep building NinjaChat by yourself.

What you'll do

Ship production features in your first week
Own whole systems: build, deploy, monitor, fix what you broke
Kill complexity: fewer dependencies, less code, faster pages
Talk to users and ship the fix the same day

What we're looking for

You can build a complete product alone: frontend, backend, infra, deployment
You've shipped something people paid for, or that broke from real traffic
You're fast and your code doesn't break. You don't treat speed and quality as a tradeoff
You read source code when the docs run out
You'd rank among the best engineers anywhere you've worked

Nice to have

You've built with LLMs beyond calling an API
Things you made on the internet: products, repos, posts
