Trailmix is a new mobile games company based in London’s vibrant Camden Town. Our growing team works collaboratively and creatively to solve problems, and we iterate quickly to make amazing games.

Trailmix founders Caro and Tristan are mobile games veterans with a combined total of 20 years in the industry. After securing funding from mobile games giant Supercell, we have crafted a team of amazingly talented people. Our company mission is simple: to combine great storytelling with the best in free-to-play mobile gaming.

You will be the first Game Data Scientist, helping us launch and operate our first game, and create amazing and customised experiences for our players. Embedded into the game team, you will be working to define, monitor and improve our game’s KPIs, and impact the game roadmap based on the result of your analysis of our players’ behaviour.

This is an amazing opportunity for a motivated individual who wants to make a direct impact on the game and the company, by working closely with our game designers and our Head of Data & Insights, as well as the broader business (UA, finance, etc.)

The responsibilities include:

  • Empower the game designers to make informed decisions by turning our game data into insights;
  • Define the measures of success for the game, and develop the analysis and reporting necessary to measure, understand and improve these metrics;
  • Design new tracking events to improve the quality and coverage of our telemetry;
  • Pro-actively spot areas of improvement for the game, and work with the game team to prioritise them;
  • Develop the A/B-testing strategy for the game, to test and improve the game continuously, as well as on an ad-hoc basis.


  • 3+ years of experience as a Data Scientist;
  • Expertise using SQL to manipulate data;
  • Experience using Python and/or R to clean, transform and analyse data and build models (churn, LTV);
  • Strong knowledge of statistical and modelling methods and the ability to match business problems to the best statistical technique;
  • Strong communication skills, with the ability to present findings and recommendations to non-technical audiences, and influence decision-makers;
  • Experience working with dashboarding / reporting tools;
  • Entrepreneurial mindset - Curiosity to find out more about game, our players and the casual f2p games market as well as proactivity driving things forward and wanting to have a real impact

Nice to have:

  • Experience working closely with Product Managers and Game Designers, ideally on F2P casual mobile games;
  • Experience working with big data techniques (Hadoop / Hive) or in balancing game economy is a plus!

Why join Trailmix?

This is an incredible opportunity for an enthusiastic, ambitious and proactive person to really make a difference and be a part of something amazing. Work with a team that has an incredible track record of making mobile mega hits. Backed by Supercell - a mobile games company that is not only known for its incredibly commercial success but also for its focus on great teams, autonomy and excellent culture - you would join a mobile gaming start-up that is brand new, highly autonomous and well funded.

Benefits include: Competitive salary, EMI share options, latest tech equipment, great team events (German Christmas Markets, Disney Castle visit, Pirate ship trip on the Thames amongst others) and being part of the amazing Supercell family.
