Java Software Developer jobs in Germany

We understand good people are always in demand. We want to preface this job ad by mentioning a few things which would hopefully convince you to work with us.

1. The extremely short version

We\'re looking for a cracked founding engineer to help us reshape the €2 trillion EU-Tender-Market. You\'ll be employee #1, own massive chunks of the product and work directly with the founders. If you\'ve ever wanted to shape a company from day one, this is it.

2. What makes this role unique

Competitive compensation: We’re not afraid to pay enough for superstars

Extreme ownership: No Jira tickets or product managers telling you what to do. You decide what to build based on real user needs.

Speed over perfection: Your code from Tuesday morning could be in production by Tuesday afternoon. We\'d rather ship something good today than something perfect next month.

Direct user impact: You\'ll see users\' reactions to your work in real-time. If this sounds exhausting rather than energizing, this role isn\'t for you.

Technical freedom: We\'re not religious about technology. If you can justify why we should use Rust instead of Python, we\'ll do it. You\'ll help shape our entire technical architecture.

About the Company

We 10xakquise.(de) work side-by-side with paying customers (we hit 15k MRR) and design partners to reshape how Europe gets built.

Every public building (stadium, school, hospital, museum etc) around you is the result of a planning office winning a public tender. Many applied, only one won. But for every firm, it costs a lot of resources.

Before AI, these costs were just costs these firms had to accept. But not anymore.

Enabled by AI, we support planning offices to win tenders 10× faster and easier. (One client saves up to €700k/year in labour costs.)

Our clients are very excited and invested, since they have never seen such a productivity boost in the tendering space (and some of them have been in business for 50+ years).

Join us to kill bureaucratic waste so planning offices can spend their energy on what actually matters: designing and building great spaces for our communities and future generations.

Why us?

• Impact from day one. You won’t be “a developer” — you’ll shape the product, company, and culture alongside the founder.
• Real customers, real revenue. We\'re not chasing an idea; we\’re scaling something that\’s already working.
• Massive market, broken status quo. Procurement is a dinosaur — we\’re modernizing it with AI.
• Velocity. You\'ll ship fast, test ideas live, and see users adopt them immediately.
• Modern tech stack. We use Typescript, React + Vite, and Convex (btw). For AI tools, see the benefit section
