About us:

We are champions of rail, inspired to build a greener, more sustainable future of travel. Trainline enables millions of travellers to find and book the best value tickets across carriers, fares, and journey options through our highly rated mobile app, website, and B2B partner channels.

Great journeys start with Trainline

Now Europe’s number 1 downloaded rail app, with over 125 million monthly visits and £5.9 billion in annual ticket sales, we collaborate with 270+ rail and coach companies in over 40 countries. We want to create a world where travel is as simple, seamless, eco-friendly and affordable as it should be.

Today, we\'re a FTSE 250 company driven by our incredible team of over 1,000 Trainliners from 50+ nationalities, based across London, Paris, Barcelona, Milan, Edinburgh and Madrid. With our focus on growth in the UK and Europe, now is the perfect time to join us on this high-speed journey.

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.

• Lead and develop a team of Data Scientists and Analysts

• Drive a high standard of work and hold a high bar for business impact

• Advance how we achieve growth in a data-driven and experimentation-led way

• Shape the strategy and delivery of marketing and product initiatives with cross-functional partners

• Think big—clearly setting out a vision and ensuring data-driven execution

• SQL, Python, R, Tableau, Power BI, AWS Athena + more!

• Think Big - We\'re building the future of rail

• ️ Own It - We focus on every customer, partner and journey

• Travel Together - We\'re one team

• ️ Do Good - We make a positive impact

We know that having a diverse team makes us better and helps us succeed. And we mean all forms of diversity - gender, ethnicity, sexuality, disability, nationality and diversity of thought. That\'s why we\'re committed to creating inclusive places to work, where everyone belongs and differences are valued and celebrated.
