What This Role is All About:
As the Information Systems Security Officer, you'll provide senior-level cybersecurity leadership and oversight across all information systems supporting the program — serving as the authoritative subject matter expert on security policy, risk management, and compliance within the Intelligence Community. This is a small team wearing many hats. You'll lead the Risk Management Framework process across multiple systems, advise program leadership and the Authorizing Official on cybersecurity risk, and manage and mentor ISSO personnel — all while making sure security architecture decisions align with mission requirements and IC/DoW directives.

What You’ll Be Doing:
• Serve as the senior security authority for all program information systems, providing oversight to ISSOs and security staff

• Lead and manage the Risk Management Framework (RMF) process across multiple systems, ensuring ATOs are achieved and maintained in compliance with ICD 503 and NIST standards

• Develop, implement, and enforce information security policies, procedures, and standards tailored to IC operational environments

• Advise program leadership and the Authorizing Official (AO) on cybersecurity risks, mitigation strategies, and residual risk acceptance

• Oversee continuous monitoring programs, security control assessments, and vulnerability management activities

• Lead incident response, forensic investigations, and after-action reporting for security events affecting classified systems

• Manage and mentor ISSO personnel, establishing clear responsibilities and security workflows

• Coordinate with IC and DoW security stakeholders, including IGs, inspectors, and oversight bodies

• Ensure security architecture and engineering decisions align with mission requirements and applicable directives (ICD 503, CNSSI 1253, NIST SP 800-53)

• Evaluate emerging threats and drive proactive security improvements across AI/ML and data platforms

• Support audits, inspections, and reviews by government oversight authorities

• Strong background in security architecture, risk management, and incident response within JWICS or similar classified networks

• Experience leading and mentoring security teams in a fast-paced, mission-driven environment
