Are you up for a challenge? Then step up to the plate — this role is for you!

 

We’re seeking a senior Java developer with several years of commercial experience, who’s worked on large, complex systems — where integrations, service dependencies, and real ownership of code matter. This project is about gradually replacing a long-standing legacy system, so we need someone who understands what it means to maintain and evolve production systems over time.

This isn’t a role where you just get tickets and check them off. You’ll think independently, analyze problems, propose solutions, and work closely with the architect while influencing technical decisions.

✅ If your experience and skills match our criteria for the role, apply for this job now. We will love to meet you!
