What you will do

• Investigate flagged accounts end to end by triaging cases, reviewing identity, behavioral, and platform activity signals, reaching dispositions, and processing removals according to policy and SLA.
• Verify identity and location signals for flagged or high-risk accounts and distinguish genuine edge cases from fraud.
• Detect multi-accounting and account integrity abuse through linked-account, device, location, and behavioral patterns.
• Prioritize manual audits by risk and signal strength while documenting evidence-backed, replicable case decisions.
• Escalate emerging fraud vectors, false-positive and false-negative patterns, and rule gaps to the fraud strategy team.
• Collaborate with Research Labs, Quality Strategy Architecture, and Forward Deployment Engineering on tooling and process improvements.

Requirements

• 5+ years of experience in trust and safety, fraud or risk investigations, or identity verification.
• Direct experience with device fingerprinting, IP and geolocation checks, document verification, or behavioral fraud scoring.
• Experience identifying multi-accounting, linked-account abuse, farming, or account sharing.
• Strong case documentation skills and the ability to prioritize high-volume queues by risk.
• Working knowledge of GDPR or equivalent data privacy obligations for case handling and retention or deletion.
• Bachelor's degree in criminology, law, criminal justice, cybersecurity, information security, data or computer science, or a related field; equivalent practical experience may substitute.

Nice to have

• Experience with AI/ML data annotation, RLHF, or research operations workforce platforms.
• Exposure to rule-based fraud detection engines and clustering or anomaly-detection approaches.
• Experience with case management, ticketing, or knowledge-base tools.
• CFE, CAMS, or IDV and identity risk vendor certifications.

• Handle sensitive data using GDPR-aligned practices.
