Introducing the Trainline Data Science & Analytics Team 👋 Data Science & Analytics (DSA) sits at the heart of how Trainline understands and improves the end-to-end customer journey, from finding a journey through to booking. Our data scientists and analysts work closely together to support supply, search and commerce, spotting patterns that affect the customer experience, identifying opportunities for our customers and our business, and building solutions that make life easier for the wider team. This role offers the chance to work across multiple areas of the business rather than being confined to a single specialism, giving you real breadth and the opportunity to see how different parts of the customer journey connect. As a Senior Data Scientist, you will take ownership of investigations and solutions that span search, supply and commerce, working with detailed datasets and linking data sources to support projects across pillars. You will collaborate closely with all teams responsible for core customer experiences (from Data, Product, Engineering, Commercial), own problems and their solution end to end, challenge the status quo and help shape how the wider team approaches recurring problems and opportunities. This is a role for someone who enjoys getting into the detail, thrives on variety, and wants to have a tangible impact on how customers experience Trainline. In this role as the Senior Data Scientist, you will... 🚄 Work across search, supply and commerce, bringing together diverse datasets to tackle complex problems and deliver projects that span multiple pillars. Identify opportunities for our customers and our business, using data to shape solutions and building tools and approaches that make the wider team more effective. Develop a deep understanding of the customer experience, getting to the root causes of recurring problems (such as conversion declines, checkout errors or searches returning no results) and working cross-functionally to turn insights into lasting improvements.
