Information Systems Security Engineer; ISSE

Information Systems Security Engineer (ISSE)

Information Systems Security Engineer (ISSE)

The Opportunity:

Are you looking for an opportunity to apply your expertise in cybersecurity, risk management, and secure system design to strengthen national defense and protect mission‑critical AI‑enabled capabilities? As an Information Systems Security Engineer (ISSE), you will identify the security controls, assessment tools, and authorization strategies needed to ensure emerging technologies are securely integrated into operational, research, and enterprise environments. Your experience will help drive the development, testing, and deployment of secure systems that safeguard missions, protect sensitive data, and reinforce our nation’s security posture.

On our team, you’ll guide and mentor professionals as they analyze complex cybersecurity challenges, conduct security assessments, and remediate vulnerabilities across varied systems and architectures. You’ll lead the creation and maintenance of RMF authorization packages, manage ATO processes, and oversee the development of key cybersecurity artifacts, from system security plans to POA&Ms. Leveraging your expertise with tools such as ACAS, SCAP, and eMASS, you’ll evaluate system risks, ensure compliance with STIGs and IAVM directives, and coordinate vulnerability remediation efforts across project teams.

In this role, you’ll make a direct impact on critical mission areas by embedding cybersecurity best practices into AI development pipelines and integrating security throughout the system lifecycle. Your work will help ensure secure deployment of advanced capabilities that support national operations, enhance readiness, and defend vital infrastructure. With hands‑on problem solving, opportunities to collaborate with Dev Ops, Cloud Architects, AI/ML Engineers, and continuous learning across evolving technologies, you’ll help shape resilient, innovative security solutions for our customers.

Join us as we strengthen, secure, and protect mission‑critical systems that support our nation today and into the future.
