Senior Software Engineer, Social Tech

The Social Tech team is now seeking an experienced Senior Software Engineer to join us in Helsinki. In this role, you’ll be part of a close-knit development team building in-game social features used across Supercell games. You’ll take strong technical ownership of core parts of our social platform end-to-end, make key architectural decisions, and help shape the platform’s technical direction together with the team. Your main focus will be on developing and operating a performant, reliable, and highly scalable backend that powers social functionality for millions of players. Our backend is written in Java (with some Rust in performance-critical parts) and runs on AWS. You’ll also contribute to our client-side Social SDK as part of a cross-functional effort that spans multiple game teams and platforms. Because our work is embedded into multiple live games, collaborating well across teams is essential. You’ll work closely with game developers and other engineers to define requirements, design great APIs, and ship features from concept to production. You must be pragmatic, humble, and willing to share learnings (including mistakes) so we can keep improving together. If you enjoy building live systems, care about reliability at scale, and want to help shape social features that reach a massive audience, you might just be the person we’re looking for!
