How you can make a difference

HealthEquity is seeking a Senior Fraud Operations Engineer to own the administration, configuration, and optimization of our Fiserv Defense Edge fraud-detection platform. You will architect and deploy real-time rules and queues, partner internally on Card Fraud Ops team, manage Defense Edge rulesets and configurations, and drive continuous tuning to maximize fraud capture while minimizing false positives. This role also partners with internal management and external clients-providing strategic updates, monthly performance reports, and rapid response support to keep our card-fraud defenses best-in-class.

What you'll be doing

Defense Edge Rule & Queue Development

Proficiently build, test, and maintain CAT Defense Edge rulesets, Policy Configuration Files (PCF), and Operational Control Scripts (OCS) to detect evolving fraud schemes.

Design high-precision queues that balance fraud interception with minimal impact on legitimate transactions.

Validate rule performance through sandbox and UAT, and coordinate production activations with zero-downtime deployments.

Fraud Strategy & Change Management

Translate fraud-ops insights into strategic rule adjustments and communicate changes clearly to internal stakeholders and external Fiserv clients.

Document rule-change rationales, maintain change-control logs, and ensure compliance with audit and regulatory requirements.

Dispute & Chargeback Coordination

Partner with Fiserv and Visa dispute-management team: ensure seamless case data transfer, escalate high-risk disputes, and track financial impacts.

Analyze dispute trends (CNP, NRI, counterfeit) to inform proactive rule adjustments and downstream recoveries.

Build and maintain dashboards tracking key metrics (approval rates, fraud loss bps, false-positive rates, queue volumes).

Prepare and deliver comprehensive monthly fraud-performance reports to clients, highlighting trends, KPIs, and action plans.

Incident Response & Forensics

Serve as primary on-call lead for Defense Edge incidents-investigate anomalies, perform root-cause analyses, and implement rapid corrective measures.

Collaborate with Internal Investigations and Fiserv support to collect evidence, launch coordinated takedowns, and refine detection logic.

Training & Documentation

Create and update runbooks, technical guides, and training materials on Defense Edge rule configuration, queue management, and fraud-ops best practices.

Conduct regular training sessions for fraud analysts and client teams to ensure consistent understanding of platform capabilities.

What you will need to be successful

5+ years in payment-card fraud operations or risk-management roles, with hands-on experience in Fiserv/First Data Defense Edge rule building.
• Demonstrated ability to configure and tune CAT Defense Edge, PCF, and OCS for real-time fraud detection.
• Strong analytical skills, including proficiency in SQL and experience building dashboards (Power BI, Tableau).
• Excellent written and verbal communication skills-adept at presenting strategy changes and performance reports to management and clients.
• Proven track record managing the full rule lifecycle: design, testing, production activation, and iterative tuning.
• Experience integrating third-party intelligence feeds into rule engines.
• Familiarity with card-processing workflows (authorization, dispute/chargeback via Fiserv).
• Prior exposure to SOAR or case-management platforms and cloud-based integrations.
