ACTIVE TS/SCI SECURITY CLEARANCE REQUIRED

Protect What Matters Most

Cyber threats don't take days off — and neither does the mission. As an Information Assurance Security Engineer supporting our Intelligence Community customer, you'll be a trusted voice on all things security: from policy and architecture to incident response and compliance. 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.

What You'll Be Doing

Policy, Compliance & Accreditation

  • 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

Operations & Incident Response

  • Conduct forensic traffic and log analysis to isolate issues and respond to analyst alerts
  • Initiate protective and corrective measures when incidents or vulnerabilities are discovered
  • Execute vulnerability remediation using ACAS security scans and related tools
  • Respond to escalated troubleshooting requests and support O&S functions for network security infrastructure
