Backend Engineer (NestJS)

Shape the future of public administration with us!

Ayunis (formerly Locaboo) is a leading GovTech startup from Munich with over 800 customers (cities, municipalities, local authorities) in the DACH region. Public sector? Doesn't that sound like bureaucracy? That's what we thought at first - until we experienced it for ourselves. The public sector is changing. After your first conversations with customers, you'll notice how open and motivated the administrative staff are. This is exactly where we come in: we make administration efficient, digital, and future‑proof. We want to shape a future in which cities, municipalities, and counties are managed completely automatically, while people focus on what's important: people. Would you like to be part of this transformation from the very beginning? Then join our team and help us shape the administration of tomorrow – for a society in which public administration works as it should: quickly, digitally, and close to the citizens.
