Cybersecurity for mission systems requires more than reacting to findings. This role leads the technical and documentation work needed to maintain an effective security posture, move information systems through Risk Management Framework ( RMF ), and sustain authorization through continuous monitoring, vulnerability management, and coordinated remediation.

As an Information Assurance Systems Administrator supporting MCTP, you will work across cybersecurity, system administration, enterprise services, communications, engineering, and government leadership to translate DoD and Army security requirements into executable controls and operational actions. You will help maintain authorization evidence, administer vulnerability scanning capabilities, assess and remediate risk, and keep stakeholders informed through working groups, technical coordination, and program reporting.
