CVE Vulnerability Expert - Security

Obsidian; San Francisco (CA); On-site; USD 120,000 - 160,000; Full time

Job summary

Obsidian is seeking a security-focused evaluator to assess the quality of vulnerability-reproduction and remediation tasks used to train frontier AI lab models. You will review fidelity of CVE reproductions, soundness of fixes, and the rigor of verification logic, within Docker-based lab environments that recreate exploitable conditions.

The role emphasizes rubric-based written feedback and collaboration with research engineers to improve reproducibility and safety.

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 (SQLi, RCE, Buffer overflows, 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.

Job description

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
