Fraud Detection Experts

Role Overview

• Mercor is seeking senior fraud detection professionals to build evaluation tasks for AI systems operating in Fortune 500 enterprise fraud and financial crimes contexts.

• The workflows are calibrated to the transaction scale, adversarial sophistication, and financial-loss stakes of Fortune 500 banks, payment companies, and large enterprises.

• Contributors design enterprise fraud detection scenarios, draft reference outputs, and write rubrics that capture how senior F500 fraud and financial crimes operators think.

Key Responsibilities

• Construct enterprise fraud scenarios spanning large-scale transaction monitoring, multi-stakeholder investigation workflows, and complex regulatory reporting cycles (SARs, CTRs) at F500 institutions.

• Build tasks across F500 payment fraud, account takeover and identity theft, anti-money laundering (AML), synthetic identity fraud, and merchant/card network fraud.

• Develop fraud operations scenarios involving tools such as SAS Fraud Management, Actimize, Feedzai, and enterprise case management/transaction monitoring platforms in F500 stacks.

• Apply enterprise fraud detection methodologies (rules-based and ML-driven detection models, network/link analysis, KYC/AML frameworks, BSA compliance) and produce reference investigation reports, risk models, and executive-level fraud narratives.

• Author rubrics that distinguish authentic enterprise fraud investigation judgment from generic textbook or certification-exam-level recall.

Ideal Qualifications

• 5+ years working in fraud detection, financial crimes investigation, or AML compliance at a Fortune 500 bank, payments company, or financial institution (JPMorgan Chase, Visa, PayPal, American Express, Wells Fargo).

• Direct ownership of F500-scale fraud detection programs, investigation caseloads, or transaction monitoring systems.

• Fluency in enterprise fraud detection tooling and methodologies, plus understanding of how F500 regulatory reporting (FinCEN, BSA/AML), law enforcement coordination, and case escalation actually work.

• Prior rubric, fraud-investigation training curriculum, or case documentation authorship is a plus.

We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.
