• Fuse Vulnerability Intelligence and Cyber Threat Intelligence into detection and prioritization—tracking exploit maturity/availability, active exploitation signals, and technique trends
• Produce high-fidelity deliverables that enable remediation and decisioning: reproducible evidence, attack-path narratives, severity/exploitability rationale, compensating control notes, and clear remediation/mitigation recommendations
• Partner across Red Team, Exposure Assessment, Threat Detection, and Vulnerability Management stakeholders

Requirements

• Minimum combined 8 years of experience in vulnerability management, exposure management, offensive security, and security engineering
