Trailmix founders Caro and Tristan are mobile games veterans with a combined total of 20 years in the industry.

Our company mission is simple: to combine great storytelling with the best in free-to-play mobile gaming.

You will work closely with the rest of our data team to develop and maintain ETL pipelines, ML models and our data infrastructure. You’ll face challenges like scaling our infrastructure with our user base, integrating new data sources into our data warehouse, and creating predictive models (user retention, monetisation, etc.). 

You will work in collaboration with teams across the business, from Game to UA and Finance, on creating value from data. 

The responsibilities include:

  • Maintain and improve our data infrastructure;
  • Develop new and maintain existing data pipelines;

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 incredible 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.
