What You'll Do • Operate vulnerability discovery and assessment tools across infrastructure, cloud, and application environments
• Prioritize vulnerabilities based on risk, exploitability, and business context, partnering with asset owners to track remediation through closure
• Apply cyber threat intelligence—including active exploitation, threat actor targeting, and emerging tactics, techniques, and procedures—to strengthen prioritization and risk scoring
• Develop mitigation strategies for vulnerabilities that cannot be patched immediately, including compensating controls, virtual patching, and automated remediation workflows
• Use AI-driven prioritization and automation to scale assessment coverage and improve remediation processes
• Produce clear vulnerability metrics and reporting for technology and security leadership
• Support penetration testing and red team engagements, coordinating remediation follow-up
• Continuously improve discovery coverage and reduce time to remediate across the environment

• Understanding of vulnerability scoring and prioritization frameworks, with experience applying MITRE ATT&CK, threat actor techniques, and exploit or CVE feeds to prioritize vulnerabilities
• Ability to design and implement mitigation and remediation approaches when patching is not immediately feasible
• Experience tracking remediation across distributed asset owners and building effective relationships across technology and the business
• Strong communication skills, with the ability to explain technical risk clearly to technical and nontechnical stakeholders; experience engaging senior executives is preferred
• Hands-on experience across on-premises and cloud infrastructure, Windows, Linux, macOS, containers, and scripting with Python, PowerShell, Bash, or similar languages is preferred
• Experience with the secure use, deployment, and governance of AI models, tools, and frameworks, and the ability to work independently in a fast-paced environment, are preferred
