The team you will be joining: Feature Platform

Wise moves billions every year for millions of people and businesses across many different countries and currencies; while bad actors constantly evolve: scams, impersonation, account takeover, money laundering, mule networks, and other forms of abuse emerge. At this scale, in order to stay ahead of evolving threats, our automated controls and machine learning models require high-quality, real-time insights. Success lies in a centralized approach that provides the necessary governance, speed, and data consistency to power these critical systems.

Wise’s centralized feature engineering platform for financial crime detection is the Feature Platform. Its goal is that every fraud signal, AML indicator, and risk feature flows through a single governed platform instead of each team maintaining siloed calculations. It owns the feature lifecycle tracks from finding, experimenting, and building data points to using them in millions of transactions daily.
