Staff Software Engineer, Fraud & Payment Risk Platform

Flex is looking for a Staff Software Engineer to build and scale our Fraud and Payment Risk Platform. You will lead the architecture and hands-on development of backend services and shared infrastructure for fraud prevention and payment risk decisioning.

The platform combines real-time, near-real-time, and offline/batch-computed risk features with business rules, machine learning model outputs, and experimentation. You will make these capabilities reliable, scalable, and observable, enabling teams to develop, validate, and launch risk strategies faster and more safely.
