We are looking for a Senior Software Engineer to join the Supercell ID team within our Player Platform organization. In this role, you will own and drive significant evolutions of Supercell ID: setting technical direction, leading high-impact initiatives end-to-end, and raising the bar for player safety, reliability, and trust across our ecosystem. Supercell ID connects hundreds of millions of players to Supercell's ecosystem. The team builds critical infrastructure and UX that links all our games and web services together into a cohesive player experience. We care about account safety, registration and login, compliance, identity, and Supercell-wide architecture for consolidating and packaging common account use cases.
Job Responsibility:
Design, build, and operate a scalable, highly available, and secure platform for hundreds of millions of players
Own systems end-to-end – from architecture decisions through production operation
Collaborate with stakeholders to define requirements
Participate in 24/7 on-call rotation for production support
Requirements:
Strong programming skills (we use Java and DynamoDB, but value experience in other stacks too)
Experience owning and operating business-critical systems – you've designed for failure, set up observability, and been woken up when things broke
A security mindset – you think about threats and vulnerabilities during design, not after launch
Ability to break down complex problems into incremental deliverables that each bring value
Familiarity with cloud infrastructure (AWS preferred) and infrastructure-as-code (Terraform)
Proficiency using modern AI-assisted development tools in your day-to-day work
Experience driving cross-team projects and working with non-engineering stakeholders
Comfort with ambiguity and a strong sense of ownership
Nice to have:
Experience with identity/authentication systems (OAuth, OIDC, session management)
Experience building multi-region systems with high availability goals
Experience developing AI-assisted engineering workflows or tooling
