Maintain and secure physical and virtual server environments running Windows Server 2019 and 2022.
Perform core identity and directory administration, including Active Directory (AD), account provisioning, and role-based access control.
Coordinate hardware maintenance, volume allocation, disk space cleanups, cache clearings, and KVM/console connectivity.
Continuously monitor infrastructure and application health utilizing enterprise observability tools such as Microsoft System Center Operations Manager (SCOM)
Serve as a Tier II / Tier III technical escalation point for messaging and server-related incidents, handling escalations from Tier I operations desks.
Track, manage, and resolve tickets using enterprise ITSM platforms (e.g., ServiceNow)
Coordinate incident resolution and operational failover procedures with partner agencies, circuit providers (e.g., DISA), and watch commanders/Battle Captains.
Document system changes, standard operating procedures (SOPs), knowledge base articles, and incident root-cause analysis (RCA) reports.
