Overview

Mercor seeks security practitioners to support a GenAI team inside a major AI lab, where the work shapes training data for large language models. You will design adversarial exercises and evaluate model behavior on red teaming, abuse prevention, and application security topics. The engagement runs part-time and remote, at least 20 hours during weekdays, through W-2 employment with Cincinnatus LLC. Your written assessments and rubrics help research and engineering groups close gaps in AI safety and security performance.

What You'll Do6

  • Coach research and engineering teams on security and responsible AI gaps that affect model behavior and training quality.
  • Create demanding security and responsible AI tasks with clear, correct solution write-ups.
  • Review submitted tasks and solutions, then deliver written technical feedback that explains your judgment.
  • Build adversarial scenarios and red team exercises that test AI systems for vulnerabilities, unsafe outputs, and policy breaches.
  • Write rubrics that measure safety, accuracy, and potential harm in model responses on sensitive security topics.
  • Partner with other subject matter experts to keep training data consistent and accurate.

Requirements5

  • 4+ years of focused work in cybersecurity, red teaming, penetration testing, threat intelligence, or trust and safety at a recognized top-tier organization.
  • Hands-on background in one or more of these areas: application security and secure code review; penetration testing and offensive security; threat intelligence or incident response; trust and safety policy enforcement.
  • A career history that shows steady growth and expanding responsibility.
  • Availability for at least 20 hours per week on weekdays.
  • Strong written communication skills, with the ability to explain complex technical decisions in accessible terms.

Preferred Qualifications2

  • OSCP, OSWE, GPEN, or CISSP certification.
  • Published CVEs, bug bounty findings, or security research.

Who Should Apply

Security professionals with at least four years in red teaming, penetration testing, threat intelligence, or trust and safety should apply. The role suits someone who can test AI systems for abuse, document findings in clear prose, and commit to at least 20 hours on weekdays.

Salary Insight

The posted rate is $90 to $140 per hour for part-time W-2 work. Specialized red teaming and AI safety skills command premium contract pay, so the range fits a senior specialist with hands-on offensive security experience. Final pay may depend on the client's evaluation and your background.
