Introducing Data Science & Analytics at Trainline👋   

Data Science & Analytics (DSA) is central to how we build products, delight our customers and grow our business.

As a Data Scientist, you will be involved in driving insights and strategy for the product team, creating and measuring value through experimentation, creating focus through metrics and goals, and building deep learning about what is most impactful for each team.  You will be able to determine the underlying dynamics of our complex ecosystem and use this to deliver insights and strategic direction, but your main focus will be a complete obsession with driving impact within the product team, drawing on whatever analytical and statistical techniques that will unlock the most benefits.    

Data Science and Analytics at Trainline exists within the wider data organisation as part of the tech org, and is complemented by data engineering teams, data platform teams, and ML teams for when deep ML and AI techniques are required.

  • 5+ years commercial experience using data science and analytics to drive business decisions. 

  • Ability to distil and communicate results of complex analysis clearly and effectively to all levels including senior management.
