Our product is a fraud-detection platform, specially designed for the betting business.

We started 2 years ago with a team created from scratch, dedicated processes and technology stack. Currently, we process, store and analyze over a billion events per day using ML and graph algorithms in real-time. We are going to reach two billion events during six to nine months adding more and more detailed data sources.

Unlike the majority of fraud-detection products available on the market, we are not wasting time on no-code/low-code and other marketing staff, focusing on our algorithms and business results instead.

You will have a direct impact on:

— Innovative solution for fraud detection;
— Real-time prediction;

— Strategic view and modelling roadmap.

Essential professional experience:

— Strong knowledge of Python (numpy, pandas, scikit-learn, etc.); 
— Experience with big data technologies;

— Good knowledge of math and statistics;
— Good knowledge of PostgreSQL, MS SQL.

Desirable skills and personal features:
