Job Description

To support our ambitious growth, we're looking for an outstanding Data Scientist (M/F/X) to join our team in Berlin, Germany starting as soon as possible.  We are striving to solve highly challenging real-world problems that have an impact (and that are NOT related to marketing!) Your tasks - Paint the world green The Challenge: Our goal is to sell the right ticket at the right time to the right person for the right price to maximize revenue. This is an extremely formidable problem as the FlixBus network is huge and highly entangled. For instance, we serve ~250 000 trips through several thousand rides each day. Airlines have faced this problem for decades, but their (rather old-fashioned) solutions are not directly applicable to the pricing structure, size and interconnectedness of the FlixBus network. Unlike a typical flight, a bus ride serves multiple trips (destination pairs), that have a shared resource: the bus capacity, i.e. number of seats. Furthermore, there are many more bus rides than flights within one day that serve the same or similar trips.  Why should you apply?  • Your work will revolutionize dynamic pricing and revenue management for large transportation networks  • Your work will have a major influence on company revenue, and hence you will be shaping the future of the FlixBus business  • You are free to employ the best-suited technologies for the problem at hand, whether it's a cutting-edge deep learning algorithm or a stochastic optimization method from the 70s  • You will have access to a rich source of data that FlixBus has collected over the past years, including sales, search requests and competitor prices  • You will join a cross-functional team of highly motivated data scientists and engineers.
