• Guide the rapid evolution of agency networks away from a static ATO process and toward an automated Continuous ATO (cATO) framework.
• Direct and coordinate teams of Information System Security Officers (ISSOs) and technical assessors.
• Interface directly with live cyber operations to ensure vulnerability scans, automated patching windows, Infrastructure as Code (IaC) change repositories, and incident response procedures are fully compliant with DoD mandates.

Required Skills & Qualifications

• Proven track record executing the end-to-end RMF lifecycle and submitting packages through eMASS.
• Demonstrated experience writing, reviewing, or consolidating enterprise SSPs, POA&Ms, and STIG compliance documentation.
