Job description

We are looking for an experienced Server Engineer to join the Brawl Stars team. As a Server Engineer at Supercell, you will be embedded in a game team, actively contributing to game design and direction. You’ll be responsible for ensuring that our tens of millions of daily players receive the best, most uninterrupted experience possible. In the Brawl Stars team you will work closely with client programmers and other team members to develop new game features. Communication between server engineers in different game teams is absolutely vital to our success, and we frequently share learnings—both successes and failures—across teams to make each team better. You must be humble, pragmatic, and willing to admit and explain your mistakes so that when something goes wrong, the team can improve.

What You’ll Be Doing

• Design, implementation, deployment, and maintenance of highly‑scalable and available backends for live games.
• Work closely with client programmers and other team members to develop new game features and actively contribute to game‑design discussions.
• Contribute to best‑practice standards on reliability and availability.
• Troubleshoot and tune high‑volume sharded database systems.
• Provide round‑the‑clock first‑line support of the production environments as part of a rotating on‑call duty.

What You Have

• Prior experience in game development and enthusiasm for games and game‑feature development.
• Strong experience in server‑side Java, including concurrency and distributed systems.
• Good experience with Linux shell and scripting languages.
• Database design and implementation skills, and good SQL knowledge.
• Familiarity with cloud computing.
• Hands‑on experience with cloud platforms (AWS, GCP, or Tencent Cloud), including automation and Infrastructure as Code (e.g., Terraform).
• Knowledge of networking, security, and cloud‑security practices.
• Proven ability to design and implement high‑performance, scalable distributed systems in a production setting.
• Ability to think clearly under pressure; the role requires rapid response and troubleshooting in a production environment with minimal downtime.
• 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.
• A self‑starter approach to using AI: finding ways to use it in day‑to‑day work, experimenting, figuring things out, and bringing the same energy to new challenges.

Would Be Nice if You Also Have

• Familiarity with ZooKeeper or similar coordination/service discovery systems.
• A track record of improving operational procedures (deployments, observability, incident response, runbooks) for production services.
• Knowledge of network protocols and non‑blocking I/O.
• Previous working experience on high‑throughput live systems is a big plus. If absent, a solid appreciation of the challenges involved is expected.
• Experience in server development without application servers.

Where You’ll Be

This role is based in our Helsinki Studio.
