At its midpoint, $166k/yr, this role pays less than the $212k/yr midpoint for Security Engineering openings today (usual band $174k–$375k/yr).

A few links on CyberJobs.cc are referral links: when one leads to a hire, a sign-up or a purchase (a lab, a course or a tool marked Partner), the company behind it may pay CyberJobs.cc a fee. You pay nothing extra, and it never changes the salary an employer offers you or which roles the board lists.

The full posting

Evaluate the quality, fidelity, and completeness of vulnerability-reproduction and remediation tasks used to train and evaluate a frontier AI lab's models. You'll assess whether CVE reproductions are faithful, fixes are sound, verification logic is rigorous, and Docker-based lab environments accurately recreate exploitable conditions - and provide clear, rubric-based written feedback.

Basic Qualifications

  • 3+ years of hands-on experience in application security, penetration testing, or vulnerability research
  • Strong understanding of CVE vulnerability taxonomy and severity frameworks (CVSS, CWE, CAPEC)
  • Demonstrated expertise in secure coding and remediation across common vulnerability classes (SQL injection, command injection, buffer overflow, deserialization, SSRF, misconfigurations, privilege escalation)
  • Experience designing or evaluating two-part verification logic (functionality tests + vulnerability tests)
  • Proficiency with Docker and Docker Compose for multi-container vulnerability reproduction environments

Preferred Qualifications

  • OSCP, GPEN, GWAPT, or equivalent offensive-security certification
  • Experience with CVE disclosure, responsible vulnerability reporting, or maintaining exploit proof-of-concept code
  • Background in DevSecOps, CI/CD security gating, or SAST/DAST tooling
  • Prior technical content review, assessment design, or QA for security-focused engineering tasks
