About

Become the Sherlock Holmes of the web and help our clients to detect the fraudsters among their customers. In this never ending race, we are beating the bad guys with technology and data analytics!

As a (Senior) Data Scientist (d/f/m), you are a member of the Analytics team, joining forces with other scientists and engineers. Our team provides a cloud solution that centralizes all our customers’ data for ad-hoc data investigation and for serving analytical product features.

Your findings will directly impact fraud prevention: you will improve our ML pipeline, innovate our products FRIDA and DEVICE IDENT, and help our customers fight fraud in their specific domain. This requires regularly presenting your results to diverse audiences, especially in German. If you think the team will benefit from your creativity and motivation, take the next step in your career and join us! We have a wonderful office in Hamburg, but we embrace a hybrid working culture and are open to a remote setup with occasional visits to the office.

Support our product development of FRIDA and DEVICE IDENT by data analysis.
Think out of the box during our regular innovation days, and leverage the latest Data Science trends, e.g. from relevant conferences, for fraud prevention.
