We're looking for a Mid-Senior Backend Engineer to design, build, and scale backend systems for a real-time multiplayer game. This is a hands-on role where you'll implement game features, optimize infrastructure, and ensure high performance, scalability, and security across distributed services.

You'll collaborate closely with production, design, and engineering teams to deliver end-to-end solutions-from architecture and development through to deployment and monitoring. You'll also build automated tests, improve observability through metrics and logging, and contribute to a strong engineering culture through code reviews and knowledge sharing.

What we're looking for:

  • 5+ years of backend/server development experience
  • Strong C# and modern .NET expertise
  • Experience with cloud platforms (ideally AWS)
  • Solid understanding of distributed systems and scalability
  • Experience with databases such as MongoDB and Redis
  • Familiarity with CI/CD pipelines and Kubernetes
Nice to have:
  • Experience with Unity or game networking concepts
  • Background in real-time multiplayer systems
  • Experience with infrastructure-as-code and observability tools
