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.

Supercell is a games company from Helsinki, Finland, with offices also in San Francisco, Seoul, Shanghai, and London. You might
know us as the makers of Hay Day, Clash of Clans, Boom Beach, Clash Royale, and Brawl Stars. Our mission is to create great games
that as many people as possible play for years and that are remembered forever.
So, how do we make great games? By putting together the best teams and giving them the freedom and independence to succeed. And by
taking risks, failing, sharing learnings, and killing lots of projects.
Independent cells and trust are at the core of our culture. But it takes more than that to make great games. We take good care of
our people, providing them with the compensation, work environment, and resources they need to succeed while having fun along the
way.
Here, you won’t need to focus on chasing titles or climbing ladders. Internally, our job titles don’t include prefixes like
Senior, Junior, Principal, or Director. Recognition isn’t tied to your title, as it doesn't define the impact you can have around
here.
Luring you in with glitter, glamour, and gems isn't what we're about. We want you to enjoy your time here fully, so we structure
our compensation and benefits with that in mind. It starts with perceiving you as a human being, not a resource.
No matter where you’re moving from, our dedicated mobility team and partners will support you throughout your move. We’ll ensure
the process is as smooth as possible for you and anyone joining you – whether they’re family members of the human or animal kind!
Many candidates with great skills and experience second-guess themselves. The bar is high, but if this role excites you, apply!
We’re here to help you succeed. Also, we're happy to learn about any specific accommodations you may need to fully engage in our
recruitment process.
Wishing you all the best,
The Supercell Recruitment team
