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.
What You'll Be Doing
- 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.
What You Have
- 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 have 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.
Would Be Nice if You Also 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.
Why This Role
- Scale: Your work reaches hundreds of millions of players across all Supercell games and services.
- Ownership: Small team, big responsibility – you'll shape technical direction, not just execute tickets.
- Impact: Supercell ID is foundational infrastructure; what you build matters to every game team and every player.
- Environment: High autonomy, low bureaucracy – we trust you to make good decisions.
