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

Stakeholder Engagement & Training

• Maintain relationships with senior personnel across multiple agencies involved in information security
• Develop and deliver security awareness training to ensure users understand their responsibilities before system access
• Present monitoring results, test reports, and findings to leadership as required

What We're Looking For

Required

• 10+ years of experience in information security, data security administration, or a related discipline
• Active TS/SCI clearance
• IAM Level II certification (per DoD 8570.01-M) required to start
• Working knowledge of ICD 503 and RMF processes
• Experience with security tools: ACAS, HBSS, Carbon Black, Tanium, RedSeal, and/or EMET
• Experience with Cloud Infrastructure / AWS-based solutions
• Scripting experience on UNIX and/or RHEL operating systems
• Experience with Microsoft PowerShell and complex macro scripting
• Hands-on experience installing, hardening, and troubleshooting network perimeter security technologies
• Working knowledge of Windows Enterprise Active Directory and VMware virtualization
• Solid understanding of network routing and VLAN technologies
• Bachelor's degree in Computer Science, a related field, or equivalent experience

Bonus Points For

• CISSP or equivalent certification (CAP, GSLC, CISM)
• System or network administration background
• System design and development experience

What to Expect Day-to-Day

This is a senior role with real responsibility and real variety. No two days look exactly alike — you might be reviewing an architecture proposal in the morning, investigating a security alert in the afternoon, and briefing leadership on remediation progress before the day is out. You'll work across IT teams, interface with multi-agency stakeholders, and be the kind of trusted advisor that programs depend on. The environment is fast-paced, team-oriented, and the mission is always in focus.
