ABOUT THE ROLE

• Create, modify, test, validate, and troubleshoot GPOs, including inheritance, precedence, OU targeting, security filtering, gpresult, and Resultant Set of Policy (RSoP).
• Administer WSUS or equivalent patching solutions, including synchronization, targeting, approvals, deployment status, failed updates, reporting, and patch-compliance remediation.
• Interpret DISA STIG requirements; use applicable STIG tools/checklists; implement and validate remediations, including GPO-based security configurations; document findings; and troubleshoot operational impacts.
• Independently administer and troubleshoot existing VMware, Hyper-V, or similar virtualization environments and virtual machines.
• Troubleshoot complex issues across operating systems, identity, applications, virtualization, storage, certificates, and network dependencies using logs and diagnostic tooling.
• Use PowerShell, Bash, and other scripting/automation methods for administration, bulk changes, data collection, troubleshooting, and repeatable tasks.
• Research and resolve unfamiliar issues using vendor documentation, technical references, logs, DISA guidance, and available tooling before requiring escalation.
• Plan and lead system changes, maintenance, upgrades, and migrations with implementation, validation, rollback, documentation, and change-control considerations.
• Serve as an escalation point and mentor for Junior Systems Administrators and Systems Administrators; provide peer review and technical guidance.
• Identify recurring problems, technical debt, security/configuration gaps, and process deficiencies and lead practical improvements within established architecture.

REQUIRED QUALIFICATIONS

• Active TS/SCI security clearance.
• Active CompTIA Security+ certification or higher DoD 8140/8570-aligned certification.
• Strong hands‑on Windows and Linux systems administration experience with demonstrated ability to work independently.
• Hands‑on experience with Active Directory, GPO administration/troubleshooting, enterprise patch management/WSUS, and domain‑connected systems.
• Experience interpreting and remediating DISA STIG findings within secure or regulated environments.
• Working knowledge of VMware, Hyper‑V, or comparable virtualization technologies.
• Strong understanding of TCP/IP, DNS, DHCP, IP addressing, subnetting, and network troubleshooting.
• Experience with PowerShell, Bash, or similar administrative scripting.
• Demonstrated ability to independently research and resolve complex technical problems, lead technical work, mentor others, and produce effective documentation.

PREFERRED QUALIFICATIONS

• Advanced Microsoft, Linux, VMware, networking, or cybersecurity certifications.
