Join a cutting-edge AI research initiative where your security expertise directly shapes the quality of frontier AI model training. As a CVE Vulnerability Expert, you will evaluate the accuracy, completeness, and rigor of vulnerability-reproduction and remediation tasks — ensuring AI models are trained on high-fidelity, real-world security content.
What You'll Do
- Assess whether CVE reproductions faithfully reflect real-world exploitable conditions
- Evaluate the soundness of proposed security fixes and remediation strategies
- Review two-part verification logic (functionality tests + vulnerability tests) for rigor and correctness
- Audit Docker-based lab environments to confirm they accurately recreate exploitable scenarios
- Provide clear, rubric-based written feedback to guide task quality improvements
Required Qualifications
- 3+ years of hands-on experience in application security, penetration testing, or vulnerability research
- Strong command of CVE taxonomy and severity frameworks (CVSS, CWE, CAPEC)
- Demonstrated expertise in secure coding and remediation across common vulnerability classes — including SQL injection, command injection, buffer overflow, deserialization, SSRF, misconfigurations, and privilege escalation
- Experience designing or evaluating verification logic for security tasks
- Proficiency with Docker and Docker Compose for multi-container 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 experience in technical content review, assessment design, or QA for security engineering tasks
