Scala Developer (d/f/m

About

Become the Sherlock Holmes of the web and help us to build software that solves real fraud cases! In this never-ending race, we are fighting the bad guys with technology.

We are looking for a Scala Developer (d/f/m) to join our product development team FRIDA.

FRIDA analyzes customers’ transactions and predicts their fraud probability. Using intelligent rule systems, FRIDA ensures that fraud correlations can be identified consistently. A comprehensive UI allows Fraud Managers to identify fraudulent transactions. Technical integration with customers’ solutions delivers automatic notifications so clients can take immediate action.

In FRIDA, we use a modern tech stack, e.g. Scala, ZIO and PostgreSQL for the backend. We use functional programming constructs and optimize our product for performance and maintain rich functionality. On the frontend, we utilize ExtJS for maintaining existing features.

We offer a landscape of interesting technical challenges and a clear product vision. Our developers are empowered to own the entire software lifecycle, making key decisions on how to implement requirements.

If you would like to get involved in actively shaping the future development of our fraud prevention product, please apply via our online platform. Your contact person is Frieda Martens-Schmidt (HR Manager). We are looking forward to your application!
