Information Systems Security ManagerThe Opportunity: Department of War (DoW) information systems require continuous, disciplined oversight to stay authorized to operate and defensible against evolving threats. As a Senior Information System Security Manager (ISSM), you will own that oversight — serving as the principal cybersecurity authority for one or more system authorization packages across their full lifecycle.You'll manage the RMF process end-to-end: categorizing systems, selecting and tailoring controls, overseeing assessment and authorization activities, and maintaining continuous monitoring posture after ATO. You'll supervise a team of ISSOs, assigning control families, reviewing their work, and consolidating it into authoritative packages in eMASS. You'll coordinate directly with Authorizing Officials (AO), Authorizing Official Designated Representatives (AODR), Security Control Assessors (SCA), and program leadership to resolve findings, manage POA&Ms, and drive packages to authorization on schedule.This role combines technical depth in NIST SP 800-53/800-37/800-137 with the leadership to run a compliance program: you'll set standards for documentation and artifact management, train and mentor ISSOs, and represent the security posture of your systems to senior stakeholders.Join us.
