About the role
About us
We’re Cortea, a Berlin startup transforming audits with AI. Manual, document-heavy audits waste expert time while demand keeps rising. Our AI-powered software and specialized AI agents remove the repetitive work so auditors can focus on judgment.
Backed by top-tier VCs with >10m funding, with a working product and paying customers, we’re rapidly scaling.
We value first-principles thinking, speed, trust, and kindness. We build side by side in our Berlin office.
Your Role
As our Senior/Staff Fullstack Engineer, you’ll ship user-facing features end to end. You’ll focus on the frontend while comfortably building APIs and shaping database models. You’ll collaborate daily with product design and founders to turn complex audit flows into fast, elegant product experiences.
What you’ll do
Own features across the stack: UI API data model tests rollout
Work closely with design to turn ideas into high-quality interfaces
Raise code quality with reviews, tests, and pragmatic performance work
Help evolve our architecture, tooling, and developer experience
