About the Job

We're a highly specialized tech startup in the heart of Berlin — working on one of the most relevant challenges of our time: bringing AI where it has the greatest impact — into the German public sector. What we build isn't theory. It's live, in production, available to more than 1 million people across most German federal states — and growing fast. As one of Germany's fastest-growing GovTech startups, something genuinely new happens here every single day. Hours fly by, weeks feel like months. A lot is happening. We've turned down VC offers. No politics, no theatre — just 100% customer focus. You'll work directly with the founders (ex-UN, ex-TR, PhDs, Studienstiftung, top-of-class) and be embedded in a small, excellent tech collective with experienced senior advisors. In short: maximum impact, minimum friction.

Your Role

Developing and improving frontend features for AI-powered products in complex public sector workflows

Building and maintaining interfaces for voice and chat applications

Integrating REST and other APIs into robust, production-ready frontend code

Contributing to architecture decisions and UX improvements based on real user feedback

Your Profile

Genuine excitement about startups (corporate mindsets won't thrive here)

Currently pursuing a Master's degree (Bachelor's already completed)

Solid experience with TypeScript, React, and Next.js

Hands-on experience with API integrations

Familiarity with AI-assisted development

What We Offer

Flexible hours

A great central office right at Rosenthaler Platz

Real ownership: your code ships to real users, fast

Direct access to founders and senior engineers

A genuine look inside one of Berlin's most interesting GovTech companies
