About The Position

Help protect customers, associates, and the business by leading end-to-end fraud prevention across analytics and field investigations.

Our Fraud Prevention & Investigations team blends analytical detection with field-based investigation to identify, validate, and disrupt fraud patterns across operations. We operate with strong operational rigor—clear workflows, audit-ready documentation, and performance reporting—so we can scale consistently while staying aligned to policy, compliance, and risk-management goals. This role connects data signals to real-world findings, ensuring insights from investigations continuously improve detection methods, tooling, and program strategy.
