Security Expert

About the Role

Mercor is building realistic, high-fidelity simulated environments to evaluate and train AI models on real-world procurement workflows for a leading spend-management technology company. We're looking for security and vendor-risk professionals to author and validate security-review tasks inside these simulated environments.

Key Responsibilities

• Review simulated vendor SOC 2 reports, security questionnaires, and pen-test evidence against a buyer's security standard
• Catch scope mismatches and lapsed bridge letters that a surface-level review would miss
• Author step-level rubrics and golden responses capturing how an experienced security reviewer would judge a request or renewal
• Assess data-handling and sub-processor risk for vendors touching sensitive data

Ideal Qualifications

• 8+ years of professional experience in security review, vendor risk management, or third-party risk (TPRM)
• Hands-on experience evaluating SOC 2 reports, security questionnaires, and compliance evidence
• Strong written communication skills; comfortable producing structured, rubric-style feedback

Nice to Have

• Relevant security certification, such as CISSP or CISA
• Prior task-writing, rubric-authoring, or AI-training data experience

We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.

• Your work at Mercor will not involve access to confidential or proprietary information from any employer, client, or institution.
• Payments are weekly on Stripe or Wise based on services rendered.
