Senior Cloud Engineer

Supercell, the Helsinki-based game studio behind Clash of Clans, Clash Royale, Brawl Stars, and Hay Day, is hiring a Senior Cloud Engineer to join its central infrastructure team in Helsinki, Finland.

Supercell runs a small number of games at massive global scale, and this role sits at the center of how the company's teams build, deploy, and operate that infrastructure. Rather than owning one game's backend, you will build the shared cloud platform and "golden paths" that every game team relies on.

Responsibilities:

• Design and maintain golden paths for infrastructure, CI/CD, DNS, monitoring, and storage using Infrastructure-as-Code templates
• Convert manual cloud operations into self-service, auditable pipelines for account provisioning and access management
• Implement cloud governance and security controls using Service Control Policies, WAF, and IAM
• Build guardrails for AI-assisted development workflows, including secrets handling and scoped permissions
• Produce documentation that is consumable by both engineers and AI agents
• Mentor engineers across teams and help set technical standards for cloud usage
• Support cost optimization initiatives across Supercell's game teams

Requirements:

• Deep expertise with at least one major cloud provider such as AWS or Google Cloud
• Hands-on proficiency with Terraform and GitHub Actions
• Strong cloud security knowledge and awareness of common threat patterns
• Solid scripting and programming skills
• IAM expertise across AWS and GCP
• Experience with SSO, OIDC, and identity providers such as Okta
• A track record of mentoring engineers and providing architectural leadership
• Comfort working autonomously on ambiguous, cross-team projects

Nice to have:

• Multi-hyperscaler experience across more than one major cloud provider
• Experience with AI agent security or MCP servers
• Familiarity with workflow automation tools such as n8n or Temporal
• Experience with internal developer portals such as Backstage
• Background in FinOps tooling or vendor management
• An interest in games, though this is not required

Visa sponsorship and relocation:

Supercell explicitly supports international hires for this role, stating that its relocation team will help with the move to Helsinki and that support is provided "not only for you, but also for your family." This includes assistance with the practical side of relocating to Finland, on top of the standard visa/work permit sponsorship for the role itself.

What Supercell offers:

• The chance to shape infrastructure used by every game team at one of the world's most successful mobile game studios
• A flat, low-bureaucracy culture where small independent teams have real ownership of their games
• Full relocation and family support for international candidates moving to Helsinki
• A permanent, onsite role based in Supercell's Helsinki headquarters

This is a full-time, onsite position based in Helsinki. Supercell is known for keeping teams small and giving engineers unusually high autonomy, so this role suits someone who wants to build platform-level infrastructure with real influence over how hundreds of engineers work day to day.
