• Interpret and analyze vulnerability results from tools such as Tenable Nessus to assess risk, identify remediation paths, and drive POA&Ms to closure. • Utilize deep technical skills to log into affected systems and directly address complex vulnerabilities across Red Hat Enterprise Linux and Windows Server workloads. • Coordinate closely with system owners, engineering teams, and cloud platform teams to implement mitigations with minimal turnaround time. • Apply strong understanding of cloud security best practices across AWS and Azure environments. • Use comprehensive knowledge of operating system internals to resolve non-standard or configuration-based vulnerabilities. • Develop, track, and validate remediation plans for findings that require configuration changes, service adjustments, or architectural modifications. • Monitor remediation progress, identify blockers, and ensure accurate and timely documentation in accordance with program requirements. • Provide technical support and troubleshooting related to vulnerability remediation activities. • Work with engineering staff to validate fixes, retest findings, and ensure vulnerabilities do not reoccur. • Participate in continuous improvement of vulnerability management processes, reporting, and operational readiness. • Work closely with the program’s Information System Security Officer (ISSO) to coordinate vulnerability remediation activities, POA&M management, and continuous monitoring. • Align vulnerability remediation efforts with RMF and ATO requirements in coordination with the ISSO. • Serve as a backup to the ISSO, providing continuity of security and compliance operations as needed. • Support preparation and updates of security documentation inputs, including POA&M updates and assessment artifacts, related to vulnerability findings.
