About the RoleAs a Fraud Engineer at Mercor, you'll help build the systems that protect the integrity of our platform at scale. You'll work on high-impact problems across identity verification, abuse prevention, and project-level fraud, partnering closely with product and engineering to understand where risk exists, quantify it, and turn that understanding into durable systems and workflows.
This role is ideal for someone who has seen fraud problems firsthand and can translate that experience into practical roadmaps, strong technical judgment, and fast-moving execution. If you don't have that experience but are interested in helping spot and catch fraud and learn fast, feel free to apply. You'll join a small team where autonomy matters and where the right person can shape both strategy and implementation from day one.
This is a role with high impact and broad scope. Your contributions will help solve an enormous challenge. This small team is responsible for keeping the platform safe and saving the company many millions of dollars annually.
You will:- Own and build fraud detection and prevention systems across multiple fraud surfaces, including identity and platform abuse.
- Partner closely with product and engineering to define a fraud roadmap, prioritize the highest-leverage problems, and ship defenses quickly.
- Design and implement tools, workflows, and backend systems that detect suspicious behavior and reduce fraudulent activity.
- Establish clearer visibility into fraud patterns, operational risk, and the effectiveness of prevention systems over time.
- Work across ambiguous, fast-moving problem spaces and independently drive large scopes of work on a lean team.
What We're Looking For- 4+ years of experience in software engineering.
- Preferred: Experience working on fraud or abuse prevention, with a strong understanding of how to translate patterns and threats into product and engineering roadmaps.
- Ability to operate autonomously and take ownership over large, ambiguous problem areas.
- Strong backend engineering fundamentals and comfort building production systems.
- A practical, high-judgment approach to balancing speed, security, and user experience.
Why Mercor- Impact: Your work will directly protect the integrity of Mercor's platform and the systems that power the future of AI work.
- Ownership: You'll help define a critical function from an early stage, with meaningful influence over both roadmap and implementation.
- Growth: You'll work closely with product and engineering leaders on some of the company's highest-priority infrastructure and risk problems.
