  • Engage with the wider development team at Supercell to help shape the future of our tech.

What You Have:

  • Experience with in-house game engine development.
  • Solid background in automated testing and mocking practices.
  • Experience with native iOS and Android development.
  • Familiarity with multi-threaded systems.
  • Ability to quickly understand and navigate large, existing codebases.

  • Driven, focused, and willing to see projects through delivery.
  • A true desire to help others produce their best work.

Would Be Nice if You Also Had:

  • Familiarity with test results visualization and dashboarding.
  • Experience in Java.

That's it about the role! Below, we've gathered some things we feel are important for you to know. Totally optional, but a highly recommended read.

Once you're ready to apply, just send us your application through the form at the bottom of the page.

About Supercell:

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, Brawl Stars, and Squad Busters . 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.

Hey, You Might Love It Here!:

Independent cells and trust are at the core of our culture. 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.

You Are Not Your Job Title ™:

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.

Benefits and Compensation:

We structure our compensation and benefits with that in mind. It starts with perceiving you as a human being, not a resource. See our compensation and benefits for details.

Relocation? Yes!:

Our dedicated mobility team and partners will support you throughout your move, whether you're moving alone or with family (human or animal).

Not Sure if You Should Apply?:

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. We're also 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
