You will work with the Experimentation track in the Marketplace corporate function for the brand.

At , 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 teams, we make it easier for 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.

In the Experimentation Track we build solutions for doing experimentation at scale with A/B testing. We enable hundreds of teams to run randomized controlled tests and make the best possible decisions about the features they release to travellers and partners. Our guiding principle is that by helping experimenters to make data driven decisions we help our business.

Our technical ecosystem includes tracking technologies that allow us to track user behaviour in more than 400 services, data pipelines at huge scale that are able to process millions of events per second, and a set of web applications that enable hundreds of teams at to run, manage and view experiments. Our technical stack includes but is not limited to NodeJs, Perl, Python and Java as Backend languages, Hadoop, Flink, Spark as Data technologies and VueJs and GraphQL for web applications.

We are looking for a Data Engineer to join our team and help us to improve the platform that supports one of the best experimentation tools in the world.
