Senior Data Scientist

Wrocław

We have a team of more than 600 experts, who know their stuff. We use common sense more often than we use the procedures. And most probably, we play the most fierce table football matches in Wrocław. We develop Enterprise-class software in the atmosphere full of the English sense of humour.

We are a software development company, one of the best in Wroclaw. Our way is quality and a great atmosphere in the office. We are looking for a new colleague: a data enthusiast, someone who is passionate about diving deep into volumes of data and can draw conclusions from it. This person interacts easily and communicates well with all process stakeholders: business, technical, and finance, along with information suppliers on the open market. The global objective of this role is to strengthen decision making, so that we operate based on hard facts rather than intuition.
