It wasn't so long ago that booking a trip to see the Eiffel Tower, stroll down New York's iconic Madison Avenue or feel the sand between our toes on Copacabana Beach was simply a matter of a few taps on our smartphone. In fact, that's what we do at We make it easier for everyone to experience the world. And while that world might feel a little farther away right now, we're busy preparing for when the world is ready to travel once more. Across our offices worldwide, we continue to innovate. To solve for some of the most complex challenges in travel and technology, and to plan for the exciting developments that lie ahead. With strategic long-term investments into what we believe the future of travel can be, we are opening up new career opportunities that will have a strong impact on our mission. We are united in the belief that our very human desire to explore the planet's beauty and discover more about other people and cultures will endure. The world is waiting for us. Together, we will be ready.

About this position

In the Experiment Track we build solutions for A/B testing; variant assignment and raw data generation. Our stack is written mostly in perl and C, but we directly support clients in perl, java, nodejs and python to enable all products and platforms at Booking to run experiments.

For us the end customer is always the priority and our solutions are designed for multi-level resiliency and graceful degradation. Data quality closely follows as a priority. We generate up to 400 thousand kafka messages per second and you can find experiment tracking information in most of the events generated by booking frontend. The variant assignment is happening over one million times per second across the entire company and we measure its latency in microseconds. Scalability and multi-level retries ensure that all of the data makes it to the processing pipelines.
