About us
We're looking for a Full Stack Developer to join our small, focused team in Vienna. You'll have real ownership over features from specification to deployment, working primarily in our modern TypeScript stack (Next.js, NestJS, LangGraphJS) while helping us migrate away from legacy PHP/Symfony code.
This isn't just a maintenance role. You'll be building new features, shaping our architecture, and directly impacting how we develop software. We value pragmatism over perfection, clean code over clever tricks, and shipping over endless planning.
Aufgaben
Build end-to-end features in our TypeScript monorepo (Next.js frontend + NestJS backend + LangGraphJS agents)
Migrate legacy PHP/Symfony code to modern TypeScript, refactoring, not rewriting from scratch
Maintain and debug existing systems across the stack
Write tests (Vitest, Playwright) and participate in code reviews to maintain quality
Collaborate through pair programming and contribute ideas to improve our processes, tooling, and engineering practices
Own your work, from database design to API contracts to UI implementation
