In one sentence, why is this role awesome?
Work building one of the most advanced A/B testing platforms in the industry.

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 make it easier for everyone to experience the world.

In the Experimentation Track we build solutions for A/B testing, enabling hundreds of teams to run randomized control tests to make the best possible decisions about the features that they expose to our customers. Our guiding principle is that by helping experimenters to make data driven decisions we help our business. 

We are looking for a Full Stack Software Developer to join our team and help us to build a world class experimentation tool. You’ll work side by side with designers, frontend and backend developers, data scientists and product managers to create services, APIs, tools and interfaces that help experimenters to test their hypotheses. Our daily work is to find the perfect mix between science, technology and user experience to empower teams in the company to use the scientific method in their product development practices.
