Etraveli Group is looking for an experienced Data Scientist to strengthen our capabilities in machine learning based price optimisation and bidding automation in our team in Gothenburg.

Etraveli Group is one of the leading flight-centric online travel agencies (OTA) in the world. The core business is airline tickets and travel related services, targeted towards high volumes of price sensitive consumers and B2B services within travel. Expertise in travel e-commerce and economies of scale together with an impressive proprietary IT platform gives us a scalable and profitable business model.

The core of the technical platform, the Internet Booking Engine (IBE), serves price comparison sites and customers with attractive travel options retrieved from centralised flight marketplaces. Every minute, millions of travel options are automatically assessed, compiled, and re-priced. Intense data analysis, price optimisation, and configuration automation is crucial in order to keep our margins high. Etraveli Group’s data stock with air search, order, and tactical competition analysis data is impressive and still growing rapidly in dimensions and volume.

Apart from that, you will also support internal customers with data integration, data research, and conceptual creative thinking around new ways to present, produce and store information. Prepare yourself for artificial intelligence development, automation of configuration options and business decisions, creative use of regression models, recommendation systems, predictive modelling, and mathematical optimisation, as well as data consolidation and data mining challenges.

The position requires a solid technical background in software development or the ability to prove the skills within the field. Strong communication skills are required. The pace is high and we always challenge each other to think creatively. To succeed in this position we believe that you have a pragmatic style and drive towards solutions with a focus on delivering results.
