    Lead Data Engineer - Enterprise Data Management

    Since Booking.com started facilitating bookings in 1996, the amount of data produced and consumed has increased in unimaginable proportions (~20TB/day), certainly from the perspective of our founders. The last decade, open source data tools (Hive, Spark, Cassandra and Kafka) running on large internal server parks enabled hundreds of colleagues working closely with data to produce various data products, e.g. in Machine Learning and Analytics. As the community has grown, so have the number of challenges around working with data. Providing flexible compute resources introduced the onset of clouds in parallel to a heavily utilized on-premise environment. Governments introduce standards for personal data protection. A growing, physically disconnected employee-base is less able to share tribal knowledge regarding data finesses. Hence, the establishment of 'Enterprise Data Management', a group governing the production and consumption of data, for it to be trusted and understood.

    The Lead Data Engineer is a technical leader who drives broad data engineering strategies and delivery across a business area. You will lead solution envisaging, technical designs, hands-on implementation as well as provide operational support across multiple data domains. You need to influence, differentiate, and guide the business and technology strategies in your area, as they relate to data, through constant interaction with various teams. You ask the right questions to the right people in order to align data strategy with commercial strategy, demonstrating deep technical expertise and broad business knowledge. You play an active role in identifying data engineering skill gaps within your area and support development of tools, materials, and training to bridge these gaps.
