Java backend engineering across the full lifecycle, on long-horizon European programs. REST APIs, services, and platforms with real domain complexity, real users, real stakes.

YOUR STACK:
Java 11+, Spring / Spring Boot, microservices, REST, CI/CD. Kafka, Docker, K8s are a plus, not a gate.

YOU:
2+ years as a Java or backend engineer, curiosity about the domain, and the patience to build things that last a decade, not a sprint. Not ticking every box? Apply anyway. We hire for trajectory, not checklists.

Competitive package, private medical care, meal tickets, flexible/hybrid working, learning budget and certifications, and the stability of a group that has been building critical technology for 130 years.

🚀
WHAT HAPPENS NEXT:
This is an open door, not a single vacancy. We hire Java continuously across our programs. Apply in five minutes, no cover letter. Answer a few short questions about your stack and seniority, and a recruiter dedicated to your domain takes it from there.
