  • Support VMware-based virtualized environments, including server hosting, configuration, troubleshooting, and modernization
  • Conduct periodic restoral testing and maintain enterprise restoration procedures
Patch Management & Cyber Readiness
  • Manage enterprise patch distribution via SCCM, WSUS, and Tanium across ESCs and regional sites
  • Submit, track, and implement approved security patch changes in alignment with CCMP processes
  • Ensure zero vulnerability incidents through proactive analysis, testing, and compliance tracking
  • Provide monthly vulnerability and patching reports to Government leads and the COR
Active Directory Standardization & Governance

  • Participate in bi-weekly "Tech Talks" with ESCs and regional sites to synchronize enterprise operations
  • Troubleshoot, isolate, and resolve complex system issues across hardware, software, and network layers

  • 2+ years of C4I systems administration experience
  • Active TS/SCI clearance (required on day one)
