• Review Assured Compliance Assessment Solution (ACAS) scan results, security configuration assessments, and application security testing reports; work with technical teams to prioritize and validate remediation.
• Assess the security impact of software releases, infrastructure changes, new integrations, and changes to the authorization boundary.
• Support continuous monitoring by maintaining current security evidence, reviewing control effectiveness, and reporting changes in system risk.
• Work with cloud and DevSecOps engineers to incorporate security requirements and evidence collection into development and deployment workflows.
• Review access controls, privileged access, audit logging, configuration baselines, and protection of sensitive data.
• Support security incident reporting, investigation, corrective actions, and updates to relevant documentation and procedures.
• Apply appropriate security overlays and support supply chain risk management activities.
• Prepare security status reports and brief Government stakeholders on authorization progress, findings, and remediation priorities.

Requirements

• Bachelor’s degree in a technical or managerial field and 5+ years of cybersecurity, engineering, T&E, or A&A experience; or a high school diploma/equivalent and more than 7 years of relevant experience.

• Active TS/SCI clearance with CI Polygraph.
• Prior Intelligence Community support experience.
• ISSO or comparable experience supporting RMF activities and system authorization packages.
• Proficiency with eMASS and ACAS.
• Experience documenting security controls, collecting assessment evidence, reviewing vulnerability and configuration findings, and tracking remediation.
• Knowledge of applicable Department of War and Intelligence Community security requirements and assessment processes.
• Understanding of system boundaries, data flows, access controls, audit logging, configuration management, and continuous monitoring.
• Ability to assess system-change risks and communicate them to technical and nontechnical stakeholders.
• Strong technical writing, organizational, and communication skills.
• Ability to meet applicable cybersecurity workforce requirements, including Full Security Control Assessor qualification if required.

Desired Qualifications
