Senior Cloud Engineer Job at Supercell (Helsinki)

Job Description

We're looking for an experienced Cloud Engineer to join the Cloud Team at Supercell. The Cloud Team provides the foundation, expertise, and support that lets every Supercell team build and operate securely, efficiently, and at scale across our multi-provider cloud environment. Our mission is to help every team use the cloud effectively and safely with minimal overhead, while making sure there are no unwelcome surprises. In this role you'll help us scale with the company's growth. As headcount and complexity increase, so does the demand on our cloud infrastructure. Rather than absorbing that linearly, we want to meet it with opinionated golden paths, automation, and self-service. You'll look several months ahead to spot scalability bottlenecks, technical debt, and emerging needs across the company, turning those into concrete technical direction and actions. You will design guardrails that minimise risk without being invasive, building paved roads that make the secure and efficient choice the easy choice. You’ll also ensure these paths work smoothly for both human developers and the AI tools or agents they use. You will operate with very high autonomy: keeping stakeholders and the team informed, and proactively deciding what makes the most sense for Supercell, so that teams can focus on creating great games.

Job Responsibility

Build golden paths
Automate high-risk operations into self-service
Own governance and security guardrails
Enable safe AI-assisted development
Write opinionated docs for humans and agents
Raise Supercell's game
Support FinOps
Be a trusted partner to technical teams

Requirements

Strong cloud computing and networking knowledge, with deep experience from at least one major cloud provider (e.g. AWS, Google Cloud)
Deep technical mastery across intersecting systems
Solid grounding in cloud security and the common threat patterns in modern cloud environments
Hands-on experience with Terraform and GitHub Actions
Strong scripting and programming experience used to automate tasks and build custom tooling
Experience with cloud identity and access management, including IAM policies, roles, and permission boundaries across AWS and GCP
Experience with application level identity, such as SSO, OIDC, and identity providers like Okta
Familiarity with Internal Developer Platforms, including AI-assisted development tools, and a clear-eyed view of their security implications
A track record of influence beyond your own work: mentoring engineers, leading architectural reviews, and setting technical standards
High autonomy
Comfortable managing priorities and tight deadlines, even when dealing with incomplete data
A humble, kind, and respectful attitude toward others and their work

Nice to have

Experience from multiple hyperscalers and a feel for how they compare
Experience securing AI agents, building MCP servers, or authoring agent-readable documentation
Experience with workflow automation tooling (e.g. n8n, Temporal)
Familiarity with Internal Developer Portals (e.g. Backstage)
Hands-on experience with FinOps tooling, reporting, and cost-optimisation experience
Experience with vendor management and direct collaboration with external partners
