About the Role

CFD Research is seeking an experienced Information System Security Manager to lead and support the authorization, operation, and continuous monitoring of classified information systems at our Beavercreek, OH facility.

The ideal candidate will have demonstrated experience managing multiple authorization packages across different government agencies, system architectures, classification levels, and mission environments. Experience supporting Special Access Programs is strongly preferred.

This position requires an individual who can work independently, coordinate effectively with technical and program personnel, and translate government cybersecurity requirements into practical, sustainable processes.

Lead the development, submission, maintenance, and reauthorization of system authorization packages in eMASS or other government-directed authorization platforms.
Manage multiple systems and authorization efforts across collateral, SCI, SAP, and other customer security environments, as applicable.
Develop and maintain System Security Plans (SSP), security policies, procedures, control implementation statements, diagrams, inventories, risk assessments, Plans of Action and Milestones, and continuous-monitoring documentation.
Coordinate directly with DCSA Information System Security Professionals, Authorizing Officials, government cybersecurity representatives, program security personnel, and customer system owners.
Interpret and implement requirements from 32 CFR Part 117, the DCSA DAAG, NIST SP 800-53, applicable Security Technical Implementation Guides, Committee on National Security Systems guidance, and customer-specific direction.
Evaluate proposed system architectures, authorization boundaries, hardware, software, connections, data flows, and classified processing requirements.
Support the development and approval of new classified systems, including proposal systems, standalone systems, peer-to-peer environments, client-server networks, and interconnected systems.
Establish and manage configuration-control, change-management, vulnerability-management, audit, patching, account-management, media-protection, and incident-response processes.
Ensure system changes are reviewed, documented, approved, and maintained within the authorized security posture.
Conduct periodic reviews, self-inspections, control assessments, vulnerability scans, and continuous-monitoring activities.
Coordinate classified-system requirements with the Facility Security Officer, program leadership, Information Technology, physical security, personnel security, and insider-threat personnel.
