Senior Full-Stack Engineer

Coperniq is building the operating system for contractors.

Our goal is simple: give contractors one system—and a team of AI agents—to run their entire business. It is a huge, underserved market, and we intend to build the company that defines it.

We’re backed by Y Combinator and Initialized Capital. We’re now looking for a strong full-stack engineer to join our small team.

You’ll work across the product, own projects end to end, and build software for complex contractor operations.

OUR STACK

Backend: Node.js, NestJS, MikroORM, PostgreSQL, TypeScript

Frontend: React, TypeScript, GraphQL

WHO WE’RE LOOKING FOR

• Startup or founding-engineer experience
• High energy and a strong bias toward shipping
• Autonomous and proactive—you can own a project without constant follow-up
• Experience building complex products across multiple domains
• Strong judgment and the ability to work through ambiguity
• 5+ years experience

• Experience building voice AI agents
• Experience building AI-powered document or image editing and annotation
