ISSO Administrator

Centrus Energy

About The Position

At Centrus Energy, cybersecurity isn’t just an IT function—it’s a mission-critical safeguard for national security. As an ISSO Administrator, you’ll be on the front lines of protecting classified information systems that support advanced nuclear operations. You’ll help ensure our IT and OT environments stay secure, compliant, and resilient by translating complex security requirements into daily operational excellence—all while working alongside cybersecurity, engineering, and classified systems experts. You’ll maintain the security posture of classified IT and operational technology systems by implementing and enforcing information system security policies, standards, and controls. From performing risk assessments and managing system changes to supporting security authorizations and continuous monitoring, you’ll ensure systems meet NIST 800-53/800-82 and NRC requirements. You’ll help evaluate security solutions, manage configuration changes, support incident recovery, and prepare critical documentation like System Security Plans (SSPs)—keeping Centrus’ classified environments secure, auditable, and mission-ready.
