Senior Trust & Safety Investigator (Mexico)

Welocalize, Inc; México; On-site; MXN 420,000 - 700,000; Full time

Job summary

Welocalize, Inc. is seeking a Trust & Safety Specialist based in Mexico to join the investigations team and handle active fraud cases, supporting the broader fraud strategy program.

You’ll come with real T&S, fraud/risk, or identity‑verification experience and run investigations end‑to‑end, verify identity signals, and prioritize cases by risk. Collaborate across teams to close cases with auditable dispositions.

Qualifications

• 5+ years in a T&S, fraud/risk, or identity‑verification investigations role — from a platform/marketplace T&S team, a fintech/payments risk team, an identity‑verification vendor, or a crowdsourced/gig‑workforce trust function
• Direct experience with identity/fraud signals — device fingerprinting, IP/geolocation checks, document verification, or behavioral fraud scoring
• Multi‑accounting / account integrity pattern recognition — you’ve dealt with linked‑account abuse, farming, or account sharing before, not just single‑account review
• Case documentation discipline — you write clean, evidence‑backed case notes that would survive an audit or an appeal
• Comfort with ambiguity and volume — you can prioritize a queue by risk, not just clear it by count
• Working knowledge of data privacy obligations (GDPR or equivalent) as they apply to case handling and data retention/deletion

Responsibilities

• Run investigations end-to-end: triage flagged accounts, review evidence (identity signals, behavioral flags, platform activity data), reach a disposition, and process removals in line with policy and SLA
• Own IDV review: verify identity and location signals for flagged or high-risk accounts, distinguishing genuine edge cases from fraud
• Conduct manual audits and reviews: prioritizing cases by risk and signal strength rather than intake order
• Detect multi-accounting and account integrity abuse: recognize patterns across linked accounts, device/location overlap, and behavioral signals
• Apply a hypothesis-driven investigation method: form a hypothesis, test it against the evidence, and reach a disposition that can be replicated and audited
• Contribute to detection improvement: elevate emerging fraud vectors, false‑positive/false‑negative patterns, and rule gaps to the fraud strategy team
• Handle sensitive data responsibly: apply GDPR‑aligned data handling and deletion practices in every case
• Collaborate cross-functionally: partner with Research Labs, Quality Strategy Architecture (QSA), and Forward Deployment Engineering on tooling gaps and process fixes surfaced by your casework
