TL;DR · Information Security Systems Engineer

Information Security Systems Engineer will join a motivated engineering team to design, implement, and sustain security solutions for National Security Systems and other government-focused systems. The role involves ensuring system accreditations by applying NIST Risk Management Framework standards, including specific publications like 800-37, 800-53, and 800-171, alongside CNNSI and FIPS requirements. Daily responsibilities include performing incident response, malware analysis, supply chain risk management, and vulnerability assessment. The engineer will develop security plans, manage system architectures for on-premises and cloud environments, and perform Static Application Security Testing using Fortify, Coverity, and Gitlab within a DevSecOps pipeline. Technical skills required include encryption technology, data flow diagramming, and experience with tools like Tenable NESSUS and Splunk. The work focuses on securing critical infrastructure through robust security controls, risk mitigation strategies, and defense-oriented technical implementations.

What you'll do

  • Design and implement security solutions for National Security Systems following NIST Risk Management Framework standards.
  • Perform cyber threat identification, incident response support, malware analysis, and supply chain risk management assessments.
  • Author critical security documentation including System Security Plans, Control Traceability Matrices, and Plan of Action and Milestones.
  • Implement and verify security controls across computing nodes, network infrastructure, and cloud environments.
  • Conduct Static Application Security Testing (SAST) and ensure STIG compliance within DevSecOps CI/CD pipelines.
  • Manage system security architectures including boundary definitions, vulnerability management, and risk mitigation strategies.
  • Develop data flow diagrams, interface control documents, and perform trade studies for systems engineering.
  • Configure and operate vulnerability analysis tools and manage SIEM audit reduction tools like Splunk.

What we're looking for

  • Must have an active Top Secret/SCI security clearance with the ability to obtain and maintain a Special Access Program (SAP) clearance.
  • Bachelor's degree and at least 6 years of relevant experience, or a Graduate degree and at least 4 years of related experience, or 10 years of experience without a degree.
  • DoD 8140.03 Level 3 or 4 certification.
  • Experience with NIST Risk Management Framework (RMF) and related publications including 800-37, 800-53, 800-171, and 800-161.
  • Ability to perform incident response, cyber threat identification, malware analysis, and supply chain risk management assessments.
  • Experience with systems/software engineering including data flow diagrams, trade studies, and SAST tools like Fortify or Coverity.
  • Experience managing security architectures for on-premises data centers and cloud environments (IaaS/PaaS/SaaS).
  • U.S. citizens.
