We are now looking for experienced Senior Server Engineers to join our game teams in Helsinki. As a Server Engineer at Supercell, you'll be embedded in a game team, working closely with other game developers and focusing on making sure that our hundreds of millions of monthly players get the best, most uninterrupted experience possible. Depending on the game and your own interests, you can focus more on the general game server infrastructure or new game feature development – and sometimes you do both.

Communication between server engineers in different game teams is absolutely vital to our success. Our server engineers frequently share learnings, both successes and failures, across game teams to make each team better. You must be humble, pragmatic and willing to admit and explain your mistakes. That way, the next time something goes wrong, we'll all be better prepared.

If you have experience in developing live systems and using virtualized computing, and you understand what it means to support a system with large user volumes, you might just be the person we're looking for!

Responsibilities

• Design, implementation, deployment and maintenance of highly scalable and available backends for live games
• Contribute to best practices on reliability and availability
• Troubleshoot and tune high-volume sharded database systems
• Periodically offer round-the-clock, first-line support to the production environments, as part of a rotating on-call duty
• Game teams are typically small, and server engineers will also have the chance to contribute to game design discussions

Requirements

• Excellent Java programming skills, including experience with server-side Java, concurrency handling, and distributed systems
• Good experience with Linux shell and scripting languages
• Database design and implementation skills, and good SQL knowledge
• Experience with cloud computing (e.g. AWS) and Terraform
• Being passionate and committed to tasks, and in general an autonomous person with high levels of initiative and energy
• An open and respectful attitude towards others and their work

Nice-to-haves

• Knowledge of network protocols and non-blocking IO
• Previous working experience on high-throughput live systems is a big plus. If absent, then at least a solid appreciation of the challenges involved is expected
• Prior experience in game development is a plus but not required as long as you are passionate about games
• Experience in server development without application servers
