We want to create a world where travel is as simple, seamless, eco-friendly and affordable as it should be.

Introducing Data Science & Analytics at Trainline đź‘‹
Data Science & Analytics is central to how we build products, delight our customers, and grow our business. Our Data Scientists and Analysts are embedded in cross-functional teams across product and marketing. They have a high degree of autonomy and are empowered to drive success, using all data and techniques at their disposal.
We are looking for a Marketing Data Science Manager to strengthen Trainline’s measurement foundations and shape how marketing decisions are made. You’ll lead a team of embedded Data Scientists who partner closely with commercial, mar-tech, and engineering teams to drive decision-making and define the future of our marketing strategy.
This is a strategic leadership role focused on enabling impact through others—not a hands-on technical position. You’ll be responsible for setting direction, supporting prioritisation, and fostering a strong test-and-learn culture across your team.
You’ll ensure Data Scientists and Analysts are embedded effectively within marketing squads, influencing roadmap decisions, and building the right frameworks to define success, measure progress, and evaluate performance. This includes advancing our experimentation practices and evolving measurement approaches such as Marketing Mix Modelling (MMM) to guide marketing investments.
As a key member of the leadership group within your pillar, you’ll collaborate with peers in Product, Engineering, and Commercial to define the long-term vision and ensure Data Science contributes to both short-term outcomes and long-term growth. You’ll also partner closely with Data Engineering, BI, and ML teams to align on priorities and advocate for the tools, infrastructure, and data quality needed to support scalable decision-making.
If you’re passionate about developing people, influencing strategy, and embedding data deeply into how teams work, this role is for you.

Our Values Represent The Things That Matter Most To Us And What We Live And Breathe Everyday, In Everything We Do
