Fraud Investigator

About the role Chime's Financial Crimes team protects millions of members from money laundering, fraud, and the organized networks that target consumer financial platforms. We work in a bank-partner model: we run detection and investigation, and we escalate unusual activity to our bank partners, who hold the filing obligation. That means our written work product is read by outside parties, and the quality bar is correspondingly high. This is a senior individual contributor role. You will set the standard for how financial crime work is done here rather than working a queue — defining what good looks like, raising the ceiling for the analysts you lead, and owning the hardest problems on the team end to end. In this role, you can expect to Operate with minimal direction on problems that arrive ambiguous, and you define the approach rather than waiting for one. Set the quality standard others calibrate to with defensible judgement calls. Move work across team boundaries without formal authority, and you are trusted to represent Financial Crimes to partners outside the function. Raise the ceiling of the people around you — through calibration, coaching, documentation, and the examples you set in your own casework. Improve the system, not just the case. Every hard investigation should leave behind something reusable: a control, a procedure, a detection change, or a documented typology. What you will own: Vendor Management. You will lead, and support, a team of analysts. Vendor team quality. You sample operations work, run calibration with partners, keep apprised of quality assurance trends, and hold quality and productivity expectations where they belong. Risk trend analysis. You understand AML and Fraud risks well enough to follow the pattern of unusual activity across accounts, devices, funding sources, counterparties, and behavioral patterns, and you can show the shape of a network in a way a non-investigator understands. Typology development. You document new and evo
