Full Stack Software Engineer - Accommodations Tech & Marketplace

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 make. The journeys you take. The sights you see. And the food you sample. Through our products, partners and people, we can empower everyone to experience the world.

The Marketplace mission is to truly understand traveler needs and behavior across multiple verticals, design and implement common traveler-facing product experiences, steward travelers to the right vertical offering, and grow Connected Trips, where travelers not only book hotels or homes, but also flights, car rentals, rides, and local attractions with us. 

Marketplace Corporate Function runs the common parts of our website and app, as well as is responsible for key Booking.com-wide capabilities, such as the User Experience, Experimentation Platform, Measurement, and operational Predictive ML models.

You will participate in a global interview process to join one of the teams of the Marketplace Tech function. If you are successful, you’ll be joining a cross-functional team in the department to innovate and maintain a set of products within our core customer journey.
