You will not be working through a constant list of tasks given to you - we warmly welcome and expect you to be assertive enough to explain to us what we should be looking into next, and really driving the analytics of the game. Your input to Hay Day’s development is crucial, and you will be an important part of our the Hay Day team. The ideal addition to the team will step in right away and make big contributions to growing the world of Hay Day. We’re an organised team looking for passionate people with big ideas, who will come through when the fertiliser hits the fan.

About the Team

As part of the Data Science Team at Supercell you’ll be embedded in the Hay Day game team, actively contributing to game design and direction.  Working on the number one farming game for mobile is a ton of fun! The Hay Day team is focused on creating the best possible experience for the players, improving the game as often as possible and consulting player feedback at every turn. There is so much we can add to the game, and so many things we can do, that not a day goes by without a decision to make.
At Supercell we believe that the key to success is continuous learning and to learn you need feedback. Your responsibility as a data scientist will be to provide that feedback. While our data scientists all sit with different game teams, communication and knowledge sharing is vital. We frequently share our learnings, both successes and failures. You must be humble, pragmatic, willing to admit and explain your mistakes and learn from others. That way we’ll all learn and keep making the team better.

About Supercell 

Supercell aims to create games that millions of people will play for years or decades to come. We believe the best people make the best games, and that’s who we’re looking for. If you love games and are passionate about playing and crafting them, and you’re looking for a job that provides you ownership and independence, you’re in the right place. 

Supercell isn’t an entertainment company, it isn’t a start-up, and it isn’t just any game company. Our focus sets us apart. Focus means saying no a lot. To release four games, we have killed fourteen. We’ve shut down marketing campaigns because they weren’t perfect for our players, and we’ve scrapped a ton of game features that were simply too niche.

We also believe that focus means staying small. We hire only the most passionate doers and arm them with the trust and support to make the biggest impact possible. As part of a small, independent team at Supercell, you’ll be free to dream and succeed (and sometimes fail) big!

If this sparked your interest, please don't hesitate to apply by sending in your CV and cover letter!

Luckily, moving to Finland is easier than you might think. No matter where you would be moving from, our dedicated people will help you from beginning to end. We’re here to make sure the process is as smooth as possible for you, your family and whoever and whatever you’re bringing along.
