Wise moves billions every year for millions of people and businesses across multiple countries and currencies. At that scale, financial crime is constantly evolving — from scams and account takeovers to money laundering and mule networks. Staying ahead of these threats means our automated controls and machine learning models need high-quality, timely insights.

The Risk Intelligence Platform team, part of Risk Machine Learning, builds the tools and automation that help Wise's FinCrime teams develop and improve those models. Our work covers areas such as model experimentation, bias and fairness, automated training-set maintenance, and threshold analysis.

Our main users are Data Scientists and Product Managers across Fraud Prevention, AML and Sanctions. We build the platform and tooling that removes repetitive Engineering work and enables these teams to focus on what matters most: identifying and preventing financial crime effectively at scale.
