About The Position

Fiserv is hiring a Fraud Investigator to support fraud prevention and detection for consumer debit and prepaid card programs offered through fintech program managers and sponsor banks. The role monitors transactional and account activity, evaluates fraud alerts, identifies emerging fraud patterns, and recommends actions to reduce losses while minimizing unnecessary customer disruption.

The investigator reviews activity across card and account channels, assesses fraud strategies and rules, conducts root-cause analysis, and recommends improvements to controls, processes, rules, or operations. The position requires timely decision-making, clear documentation, and collaboration with technical, operational, risk, compliance, client, and bank stakeholders.

Candidates must currently have valid and unrestricted U.S. work authorization. Temporary visa holders and candidates who require sponsorship now or in the future will not be considered. The position is not eligible for an annual incentive opportunity or commissions. The stated salary range applies to employees in New Jersey and New York; ranges may differ in other states.

• Proficiency with Microsoft Excel and experience working with large datasets, fraud-monitoring platforms, dashboards, or reporting tools.

• Strong written documentation skills, including preparing concise case narratives, trend summaries, and management reports.
• Ability to balance fraud-loss reduction with customer experience and legitimate transaction approval.
• Ability to manage multiple alerts, investigations, incidents, and remediation items in a deadline-driven environment.
• Strong communication and collaboration skills across technical, operational, risk, compliance, client, and bank stakeholders.
• Valid and unrestricted U.S. work authorization; sponsorship is not available now or in the future.
