Job description

What you\'ll actually do

Author realistic fraud scenarios from first alert through case disposition, the kind a working investigator actually handles. Write reference answers with the investigative reasoning behind each decision, from transaction patterns to interview strategy. Grade model output for investigative soundness, evidentiary rigor, and completeness. Flag conclusions that read plausible but the evidence does not support, the leaps a trained investigator would never make.

Who this is for

Fraud investigators with at least two years of professional casework in payments, insurance, AML, or corporate investigations. Practitioners who work real investigative methods, from transaction analysis and open source research to interviews and case files. CFEs, former law enforcement, and regulatory investigators are all strong fits. People with strong written English who can turn investigative instinct into clear, teachable reasoning.

Contract and pay

$70 to $85/hr, paid weekly via Stripe. Your rate is set from your experience, not negotiated down after you start. Fully remote, fully async. No fixed hours. Minimum 10 hours per week, no maximum. Scale up or down week to week. No screen recording, no keystroke monitoring, no idle timers. Independent contractor. Ongoing project work rather than single task batches.
