Your expertise will directly shape how systems are built, protected, and sustained in one of the most consequential environments in the country.
If you're a seasoned security professional who thrives at the intersection of policy, engineering, and operations — and you want your work to mean something — keep reading.

Draft and review information security policies, Memoranda of Agreement (MOAs), and System Security Plans (SSPs)
Lead and coordinate all aspects of Certification & Accreditation (C&A) and Risk Management Framework (RMF) processes
Review Plan of Action & Milestones (POA&Ms) and drive technical remediation and lien resolution
Ensure IA hardware, software, and configurations comply with established security guides and A&A documentation
Architecture & Engineering
Advise on system design and architecture from a security-first perspective — working with developers, engineers, and project managers to build protection in from day one
Define, design, and evaluate information security systems and multi-agency integration security
Perform advanced configuration and maintenance of network security infrastructure: firewalls, web/mail gateways, IDS, load balancers, and performance monitoring tools
