Job description

Troubleshoot and resolve complex technical issues escalated from Tier I and Tier II. This includes problems related to network connectivity, virtual desktops (VDI), domain authentication, print services, and application access. Provide rapid and effective response to maintain user productivity.
Process AMC tickets by performing endpoint provisioning, IP address assignment via DHCP or static configuration, switch port activation, DNS/DHCP updates, and port security validation. Ensure changes are logged, tested, and documented per change control policy.
One FTE is designated to provide concierge-level IT support for approximately 75 General Officers and VIP users. This includes rapid response to service disruptions, proactive system checks, and discreet, onsite or remote assistance tailored to executive schedules.
Assist with user account creation, disabling, unlocking, and access troubleshooting across Active Directory (AD), VDI, and other DISA-managed systems. Ensure changes are compliant with security protocols and properly authorized.
Use the approved ticketing system to document, assign, update, and close service requests. Maintain professional, customer-focused communication throughout the ticket lifecycle to keep users informed of progress and resolution timelines.
Maintain internal troubleshooting guides, resolution SOPs, and AMC process documentation. Contribute to the creation of job aids and training materials to improve Help Desk efficiency and reduce repeat incidents.
Provide IT continuity support during Continuity of Operations (COOP) events, including prepositioning of equipment, alternate site readiness, and user migration assistance.
Assist with enclave monitoring tools to track system health, identify trends, and escalate alerts to Network Engineers or Cybersecurity Technician as needed. Contribute to weekly and monthly performance summaries submitted to the Site Lead and Program Manager.

Requirements

Minimum 4-6 years of IT support experience, preferably in DoD or classified environments.
Ability to resolve complex end-user issues related to hardware, VDI, networking, and software systems.
Strong customer service skills, particularly in supporting senior leadership and VIP personnel.
Familiar with ITSM tools (e.g., Remedy, ServiceNow), AMC tasking, and COOP operations.
Security+ Certifications and ITIL Foundations (preferred)
