Introducing Data Analytics at Trainline

Data Analytics is central to how we build products, delight our customers and grow our business. Our Data Analysts are embedded across cross‑functional teams which exist across product and marketing. They work closely with Product Managers, Software Engineers and Commercial and partner directly with Embedded Data Scientists and wider data functions. They have a high degree of autonomy and are empowered to drive the success of their teams by enabling the build, measure, learn cycle.

As a Data Analyst you will be involved in driving insights into user acquisition, and marketing efficiency to enable us to set an impactful growth strategy. You’ll create focus and accountability in teams by setting metrics and goals, ensure we’re learning as we progress through experimentation and ensure we’re feeding insights back in to marketing decision making. Ultimately this will require a complete obsession with driving impact within the marketing teams, drawing on a broad range of analytical and statistical techniques to unlock the most benefit.

As a Senior Data Analyst at Trainline, you will…

• Own the full marketing analytics lifecycle in an embedded marketing team
• Deep‑dive into acquisition and marketing trends, uncover friction points, and size opportunities
• Define north star metrics, primary KPIs, and guardrails for features and experiments
• Design, execute and analyse A/B tests using sound statistical principles (MDE, power, duration, etc)
• Translate findings into clear, actionable recommendations to help drive product strategy
• Build data models and pipelines with support from Data Engineering and Data Scientists

We’d love to hear from you if you have…

We’re looking for someone who thrives in a product‑first environment and wants to use data to drive real‑world user and business outcomes.

• Proven ability to partner cross‑functionally with Product, Engineering and Design
• Strong data visualisation skills using tools like Tableau, Spotfire, Power BI etc.
• Ability to communicate insights clearly and tailor messages for both technical and non‑technical audiences
