This role combines advanced analytics, an investigative mindset, and real-world context to detect emerging threats and protect the integrity of the system.
The ideal candidate thrives in ambiguous problem spaces, thinks like an adversary, and can translate complex behavioral patterns into actionable insights and defensible decisions. This role acts as a critical bridge between operational investigations, product/tooling enhancements, and broader fraud-prevention strategy.
Essential FunctionsFraud Detection & Behavioral Analysis- Analyze user behavior and platform interaction patterns to identify unusual activity, suspicious accounts, and emerging fraud vectors at scale.
- Apply core analytics fundamentals-segmentation, trend analysis, anomaly detection, correlation testing-to uncover fraud patterns across large datasets.
- Interpret mixed signals by combining data points such as GPS movement, device details, metadata, and behavioral indicators to assess risk.
- Apply real-world context and consider cultural, social, and environmental factors that automated systems might miss.
Fraud Signal Development & Model Support - Build and refine fraud indicators-measurable behaviors, thresholds, and composite signals that can be monitored through dashboards and automated models.
- Identify motivations and opportunities for fraud; translate hypotheses into testable data signals and validation frameworks.
- Stress-test queries by enumerating legitimate scenarios, then refine logic, thresholds, and exclusion rules to minimize false positives.
- Provide structured feedback and business requirements that support new fraud-signal development or detection-tool enhancements.
Investigation & Evidence Documentation - Follow a structured investigation process, documenting each step clearly from initial detection through final decision with audit-ready case files.
- Use open-source research (OSINT) to look beyond internal data, confirm identities, and uncover external fraud clues or coordinated networks.
- Prepare clear, defensible reports and documentation that would stand up in audits or legal settings.
- Stay ahead of threats by thinking like a bad actor to anticipate how people might try to exploit the system next.
Cross-Functional Collaboration & Reporting - Present operational insights to Product, Legal, Compliance, Engineering, and Care Operations to inform tooling improvements and policy updates.
- Provide operational context that supports broader fraud-prevention strategy and product design decisions.
- Produce clear, structured summaries of operational findings, QA trends, and SOP gaps that inform program updates.
- Ensure all documentation supports audit readiness and compliance expectations.
Minimum Qualifications - Bachelor's degree in Criminal Justice, Data Analytics, Business, Information Systems, or related field and 3+ years' experience in fraud detection, investigations, risk analysis, or compliance-OR 5+ years' equivalent experience without a degree.
- Proficiency in SQL and advanced Excel for large-scale data analysis, anomaly detection, and pattern identification.
- Experience with structured investigation processes, evidence documentation, and audit-ready case file management.
- Strong analytical and critical thinking skills with the ability to interpret complex, mixed-signal data and draw defensible conclusions.
- Effective written and verbal communication skills; able to distill complex findings into clear reports for cross-functional audiences.
Preferred Qualifications - Experience in gig economy, marketplace, or platform fraud-detection operations.
- Experience with OSINT techniques, device forensics, geolocation analysis, or identity-verification processes.
