Mercor is partnering with a leading AI research lab on a Frontier Code Agents project. As a contributor, you'll evaluate and improve cutting-edge AI coding models through structured security engineering assessments. This is a sprint-based, flexible engagement — spots are limited and filling fast.
What You'll Do
- Use frontier AI coding agents to complete and evaluate complex security engineering tasks.
- Review model-generated code and architectures for vulnerabilities, security risks, and implementation flaws.
- Identify bugs, edge cases, and security-related failure modes in AI outputs.
- Compare outputs across multiple frontier models and assess their relative strengths and weaknesses.
- Apply professional engineering judgment to realistic, production-grade security scenarios.
Compensation & Time Commitment
- $400 per accepted task — typical tasks take approximately 2–3 hours after initial 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 security engineering experience.
- Background in application security, cloud security, infrastructure security, vulnerability management, or security tooling.
- Regular hands-on use of AI coding agents such as Cursor, Claude Code, Codex, Windsurf, Gemini CLI, or similar tools.
- Demonstrated ability to identify flaws in model-generated code and system architectures.
- Experience securing production systems is strongly preferred.
