The Opportunity

The Fraud Investigator plays a critical role in protecting the financial assets, operational integrity, and reputation of Nymbus clients by leading advanced investigations into complex and high-impact fraud cases across multiple payment channels and products. This role involves the proactive identification of suspicious patterns and anomalies through the review of transactional data, case alerts, and non-alert-based referrals from both internal and external sources.

The Investigator will perform in-depth case analysis, connect cross-channel and cross-client fraud activity, and determine the root cause of fraudulent behavior. They will work directly with clients to present investigative findings, provide recommendations for risk mitigation, and ensure timely resolution of escalated cases. This includes preparing comprehensive reports, tracking key trends, and recommending targeted process enhancements.

Collaboration is essential, as the Fraud Investigator partners closely with internal operations teams, external client contacts, and third-party fraud detection platforms to resolve cases efficiently and in compliance with regulatory standards. The role also involves drafting and maintaining investigative procedures, mentoring Fraud Analysts, and contributing to the development of enterprise-wide fraud prevention strategies.

The ideal candidate will have proven expertise in fraud investigation, strong pattern-recognition skills, deep knowledge of financial regulations, and the ability to work effectively under pressure in a high-volume, deadline-driven environment.
