Fraud Engineer (AI Coding Agent) at Mercor

Fraud Engineer (AI Coding Agent) | $400/task (~$80/hr) | Worldwide Remote | Contract

Mercor is partnering with a leading AI research lab on a Frontier Code Agents project. As a Fraud Engineer contributor, you'll evaluate and improve cutting-edge AI coding models through structured technical assessments — focusing on real-world fraud, risk, and trust & safety engineering workflows.

Spots are limited and filling quickly on a first-come, first-served basis.

What You'll Do

• Use frontier AI coding agents to complete and evaluate complex fraud and risk engineering tasks.
• Review model-generated implementations involving fraud detection systems, risk scoring models, abuse prevention tooling, and transaction monitoring systems.
• Identify bugs, edge cases, and failure modes in AI-generated code.
• Compare outputs from multiple frontier AI models and assess their relative strengths and weaknesses.
• Apply professional engineering judgment to realistic fraud and risk engineering scenarios.

Compensation & Time Commitment

• $400 per accepted task — typical tasks take approximately 2–3 hours after ramp-up.
• Sprint-based project running in 12–24 hour stretches based on client requirements.
• Compensation is tied to accepted, quality work.

Who Should Apply

• 2+ years of professional experience in fraud engineering, risk engineering, trust & safety, or related domains.
• Hands-on experience building fraud detection systems, risk scoring models, abuse prevention tooling, or transaction monitoring systems.
• Regular use of AI coding agents such as Cursor, Claude Code, Codex, Windsurf, Gemini CLI, or similar tools.
• Ability to critically evaluate model-generated solutions in fraud and risk contexts.
• Background in fintech, payments, marketplaces, or large-scale consumer platforms is strongly preferred.
