We are helping our partner — a fast-growing product company in the iGaming space — find a Senior Java Developer to join their backend team.

This is not a “just write code” role.

This is about building systems, making decisions, and owning the result.

What this role is really about

You’ll be working on a high-load casino product, where:

  • systems process real-time events
  • performance matters
  • architecture decisions have real impact

The team builds services from scratch and owns them end-to-end.

What you’ll be doing

  • Build new backend services from scratch
  • Participate in architectural and technical decisions
  • Work with microservices and distributed systems
  • Solve complex technical challenges
  • Collaborate in a cross-functional team (product / QA / dev)
  • Take ownership of what you build — not just tasks

What we’re looking for

  • 5+ years of experience with Java
  • Strong experience with microservices architecture (2+ years)
  • Deep understanding of distributed systems
  • Hands-on experience with:
    • Spring Boot
    • PostgreSQL
    • Kafka (or similar messaging systems)
    • SQL + NoSQL databases
  • Experience with AWS / Kubernetes will be a strong plus
  • gRPC — nice to have

But more importantly:

You think, not just code

You take ownership

You can explain your decisions

What you get

  • Product company (not outsourcing)
  • Real impact on architecture and product
  • Strong engineering team
  • Fast-paced environment with real challenges
  • Remote work
