Senior Server Engineer, Central Tech

Are you ready for the challenge of building game server platforms that handle global scale? Do you get excited by owning critical server infrastructure that serves hundreds of millions of players?

We're looking for an experienced Senior Server Engineer to join Supercell's Central Tech organization in Helsinki. Our core mission is to let game teams focus on creating great player experiences by giving them robust, scalable and easy-to-use server technology.

As a Senior Server Engineer, you'll own core server parts of Supercell’s own game engine, the platform every Supercell game builds on, and work closely with our game teams to keep it fast, reliable and easy to use. To give you a sense of scale: processing ~15 billion game events/day, storing 5TB of data/day, and working with thousands of game servers. Recent problems the team has worked on include dynamic scaling of stateful systems, downtime reduction, server performance optimization, and dynamic game content delivery.

Game development at Supercell is a team sport. We value humility, pragmatism and open collaboration. Central Tech engineers work seamlessly with game teams and other central teams, and we expect you to share experience and lessons across teams, both successes and failures.

Ps. Did you know we have our own game engine?This article explains why you've probably never heard of Titan, while this more technical article is about making Brawl Stars toilet break-friendly.

What You'll Be Doing

• Design, build, and evolve core backend game systems, including operational tooling, server frameworks and server-side delivery systems for the game teams.

• Innovate on the use of AI technologies in the realm of robust, scalable server technology.

• Take technical ownership of critical parts of central game server technology, from design to production, and be accountable for their reliability and performance.

• Collaborate closely with game teams to understand their needs and help them get the most out of central systems.

• Investigate and resolve production incidents affecting players, and drive the long-term fixes.

• Take part in the on-call rotation, providing first-line support for production

• Set technical direction in your area: lead design decisions, mentor other engineers, and contribute to best practices around scalability, reliability, availability, security, and operability.

• Improve operational procedures for our infrastructure and services.

• Share knowledge and lessons across Central Tech teams.

What You Have

• Strong server-side experience in Java, including concurrency and distributed systems.

• A track record of designing and building high-performance, scalable distributed systems.

• Experience operating live production systems with large user volumes, including debugging them under pressure.

• Experience with a major cloud platform (AWS or GCP), automation, and Infrastructure as Code.

• Strong communication and collaboration skills, and a humble, pragmatic, and respectful approach to working with others.

• Ownership and curiosity: you take initiative, learn quickly, and see problems through.

• Interest in AI tools: you use them in your engineering work or are keen to experiment, and you're curious how they change the way we build and operate systems.

• Care for building technology that helps others succeed, and ideally a love of games.

Would Be Nice if You Also Have

• Experience with large-scale containerized environments (e.g. EKS, ECS, Fargate, GKE).

• Terraform or similar IaC tools.

• Strong SQL and database design experience.

• Linux, shell scripting and automation.

• Knowledge of networking, security and cloud security practices.

About Supercell

Supercell is a games company from Helsinki, Finland, with offices also in San Francisco, Seoul, Shanghai, and London. You might know us as the makers of Hay Day, Clash of Clans, Boom Beach, Clash Royale, and Brawl Stars. Our mission is to create great games that as many people as possible play for years and that are remembered forever.

So, how do we make great games? By putting together the best teams and giving them the freedom and independence to succeed. And by taking risks, failing, sharing learnings, and killing lots of projects.

Hey, You Might Love It Here!

Independent cells and trust are at the core of our culture. But it takes more than that to make great games. We take good care of our people, providing them with the compensation, work environment, and resources they need to succeed while having fun along the way.

You Are Not Your Job Title ™

Here, you won’t need to focus on chasing titles or climbing ladders. Internally, our job titles don’t include prefixes like Senior, Junior, Principal, or Director. Recognition isn’t tied to your title, as it doesn't define the impact you can have around here.

Benefits and Compensation

Luring you in with glitter, glamour, and gems isn't what we're about. We want you to enjoy your time here fully, so we structure our compensation and benefits with that in mind. It starts with perceiving you as a human being, not a resource.

Relocation? Yes!

No matter where you’re moving from, our dedicated mobility team and partners will support you throughout your move. We’ll ensure the process is as smooth as possible for you and anyone joining you - whether they’re family members of the human or animal kind!

Not Sure if You Should Apply?

Many candidates with great skills and experience second-guess themselves. The bar is high, but if this role excites you, apply! We’re here to help you succeed. Also, we're happy to learn about any specific accommodations you may need to fully engage in our recruitment process.

Wishing you all the best,

The Supercell Recruitment team
