What you will need to have:

• Three or more years of experience in fraud monitoring, fraud operations, card risk, payment operations, banking operations, financial crime or a related field.
• Experience analyzing debit, prepaid, credit, ATM, digital-payment or account-level transactional activity.

• Ability to recognize suspicious patterns, assess risk and make timely decisions using incomplete or rapidly changing information.
• Strong written documentation skills, including the ability to prepare 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.

What would be great to have:

• Experience supporting a debit or prepaid card issuer, fintech program manager, sponsor bank, issuer processor or Banking-as-a-Service environment.
• Familiarity with card authorization data, fraud-rule management, account takeover, identity fraud, card testing, BIN attacks, counterfeit activity, digital-wallet fraud, ATM fraud and lost-or-stolen card fraud.
• Knowledge of Visa or Mastercard rules and card-industry fraud-monitoring practices.
• Experience with SQL, Power BI, Snowflake, Splunk, Python or comparable analytical and reporting tools.
• Experience evaluating fraud rules, thresholds, models, or decision strategies.
• Knowledge of Regulation E, prepaid account requirements, BSA/AML considerations, privacy obligations and payment-card security requirements.
• Professional certification such as Certified Fraud Examiner or another relevant fraud, risk, payments or financial-crime credentials.

You must currently possess valid and unrestricted U.S. work authorization to be considered for this role. Individuals with temporary visas including, but not limited to, F-1 (OPT, CPT, STEM), H-1B, H-2, or TN, or any candidate requiring sponsorship now or in the future will not be considered for this role.
