Principal Data Engineer (Data & AI, Marketplace)

• Operate across Marketplace Data & AI’s tracks — Traveller Intelligence, Experimentation, Benefits & Relevance, AI Experience — connecting and understanding stakeholders across a fast-growing, multi-track organisation
• Design and build the data models, pipelines, and interfaces that let one track’s data be discovered, trusted, and used by another, applying data product or data mesh thinking where it genuinely fits
• Get hands-on with the hardest data problems yourself: complex Spark/Flink pipelines, tricky modelling decisions, performance issues nobody else has been able to crack
• Propose what “good” looks like for shared data infrastructure at Booking.com, and pressure-test that thinking with architects, principals, and leads across tracks before asking anyone to adopt it
• Work closely with SEMs, GPMs, and EMs across tracks to make sure any shared data investment is driven by what product teams actually need to build, not architectural elegance for its own sake
• Architect data foundations that stay relevant as MPDAI’s tracks and priorities take shape
