Cyber System Administrator (Vulnerability Analyst) supports the Distributed Mission Operations Center (DMOC) Battlespace by operating and maintaining mission‑critical systems that power Live‑Virtual‑Constructive training for Air Force, Joint, and Coalition warfighters. In addition to traditional system administration duties, this role includes ensuring all DMOC systems meet DoD cybersecurity requirements for configuration compliance, STIG hardening, patching, vulnerability remediation, and cyber‑readiness. An Active secret security clearance is required prior to starting. You will work closely with network, software, cybersecurity, and simulation system teams to maintain a secure, resilient, high‑fidelity training environment for the warfighter. In this role, you will: Maintain reliable operation of Windows and Linux systems in a hybrid classified environment. Coordinate with network admins, engineers, and end users to ensure smooth system performance. Install, configure, and maintain server/workstation hardware, peripherals, and VTC equipment. Administer Active Directory accounts, groups, policies, file permissions, and security access lists. Support technical activities according to mission schedules.

Participate in monthly POA&M reviews, providing input on vulnerability timelines, risk justifications, and fix‑action feasibility. Provide timely feedback to the Cybersecurity team on vulnerabilities, patching issues, impediments, system outages, or conflicts with mission operations. Assist in maintaining data integrity by monitoring system configuration, change control, and compliance posture. Recommend, test, and deploy system enhancements that improve security, performance, and reliability. Test new product releases, patches, or updates for compatibility and minimal user disruption prior to deployment. Monitor, control, and troubleshoot DMOC data communications networks. Record issues, open trouble tickets, support system problem reports, and assist with LAN/WAN testing. Configure and support VTC connections among local and remote network participants. Diagnose and resolve connectivity, hardware, and system performance issues. Ensure strict adherence to DoD and DMOC Information Systems Security policies. Work closely with DMOC Cybersecurity personnel to align system maintenance with cyber‑hardening requirements.

Translate technical findings into repair actions, risk statements, and user‑friendly instructions as needed. To be successful in this role, you will have: Bachelor Degree and a minimum of 2 years of relevant experience.
