About the Role

Love clean code, lightning-fast backends, and the thrill of a good technical puzzle? Come help us power the engine behind our gaming loyalty platform! You’ll be designing and building scalable backend services that actually matter — and have fun doing it.

We’re looking for someone who’s ready to dive deep into high-performance backend systems, tackle juicy technical challenges, and make a real impact on millions of users. Sound like your kind of adventure? Let’s talk.

Oh — and we’ll keep you up to date with the latest tech and tools so your skills always stay sharp.

• Keep our backend running smoothly, fast, and failure-free

• Shape and refine our microservices setup for clean, modular magic

• Own your code — and love it like a favourite hoodie

What You Bring

• Serious Java chops (OOP, design patterns — the works)

• Fluent in SQL (MySQL) and cool under database pressure

• Cloud-savvy (GCP is a plus), and a fan of microservices

• Love solving complex problems like it’s your favourite hobby

Bonus Points for:

• Experience with Kotlin on the backend (we like it too)

• You’ve played with Google Guice, Gradle, Liquibase, gRPC, or Terraform

• You read release notes for fun (okay, maybe not fun, but still)

What’s In It for You?

• Your office, your rules – Work remotely, from Berlin HQ, or a blend of both

• Stock options (VSOP) – Because your work should pay off in more ways than one

• Mental wellness – Free coaching via nilo.health, because burnout isn’t our style

• Keep learning – €2,000/year for courses + free Chatterbug language lessons
