The team

Data is a core component of future travel. We are looking for innovative and productive summer workers for our growing year-old team. Our aim is to use data to enable a more personalized customer experience, optimize business and plan processes in addition to enhancing product development and service design. Our team consists of professionals in data science, data engineering, cloud computing, business intelligence, and customer insights.

Why should you apply?

In our team you will be able to further your technical skills as well as gain understanding of the business. We’ve hit the ground running which you’ll see especially in our agile development and in an experimental working culture. The data and analytics platform we are building is already in production in AWS’s cloud, and data-science work is possible in a scalable cloud environment. The data is flowing real time and we have a bunch of analytics applications ready for business. The team shares a common curiosity of technology and a desire to do something that helps hundreds of thousands of travellers to choose the environmentally more sustainable option.

Our cloud warehouse has plenty of new data sources which are waiting to be utilized: VR passenger traffic owns tons of data on travelling and tickets (sales, seat reservations, check events, restaurant car sales), customers (CRM, Google Analytics), work shifts, train schedules, and punctuality.
