**About Us: **At Booking.com, data drives our decisions. Technology is at our core. And innovation is everywhere. But our company is more than datasets, lines of code or A/B tests. We’re the thrill of the first night in a new place. The excitement of the next morning. The friends you encounter. The journeys you take. The sights you see. And the memories you make. Through our products, partners and people, we make it easier for everyone to experience the world.
We are hiring two Senior Data Scientists in the Marketplace Department at Booking.com, each aligned to a distinct sub-scope:
- Loyalty & Incentives Insights: We drive the strategy of our Genius and Incentives programs through rigorous experimentation and incrementality measurement. We aim to understand traveler loyalty and build scalable frameworks that optimize our commercial incentives, working in close collaboration with ML and Product stakeholders
- Trip Management & Order Insights: We focus on improving the traveler experience by providing the right help when needed and enabling communication between travelers, partners, and customer service. We build scalable product solutions — including GenAI-powered ones — to the most significant and persistent decision-making challenges in the trip management space.
**Role Overview: **
As a Senior Data Scientist in either sub-scope, you will work autonomously on impactful strategic business problems, translating them into data stories and delivering insights that inform business decisions across multiple products. You will design and interpret experiments to guide long-term strategic decisions, build proofs of concept and prototypes, and actively manage stakeholders from operational to Senior Director level. You'll collaborate cross-functionally with Product, Engineering, and Data Engineering teams, writing high-quality, reproducible code to ensure your work lands impactfully and enables solid decision-making across leadership.
