Description

Responsibilities

Mid-level Network / Desktop Administrator to support and maintain enterprise network and end-user computing infrastructure. This is a hybrid role combining hands-on switching and network support with desktop/endpoint administration. The ideal candidate is comfortable working across the stack — from configuring VLANs and port security on Cisco switches to imaging endpoints and troubleshooting Windows 10/11 clients — while delivering responsive, professional customer support to end users. This role balances infrastructure work with day-to-day operational support and requires someone who can work independently on routine tasks and escalate appropriately on complex issues.

  • Configure, maintain, and troubleshoot Cisco switches running IOS-XE and NX-OS.
  • Implement and manage port security, including MAC-based controls and violation remediation.
  • Support enterprise network fundamentals: TCP/IP, subnetting, DHCP/DNS behavior, and Layer 2/Layer 3 troubleshooting.
  • Support and help maintain VDI / thin-client infrastructure, including endpoint provisioning and connectivity troubleshooting.
  • Perform endpoint imaging and deployment via PXE boot and associated deployment tooling.
  • Administer Windows 10 and Windows 11 endpoints, including configuration, troubleshooting, and lifecycle support.
  • Execute patch management and remediate vulnerabilities in response to IAVAs, ensuring systems remain compliant with security baselines and STIGs.
  • Use CLI and administrative tooling — PuTTY, PowerShell, and Windows CMD — for configuration, diagnostics, and routine automation.
  • Support STE/STN environment and associated operational procedures.
  • Perform Active Directory tasks such as account and group management, OU navigation, and basic Group Policy awareness.
  • Document configurations, procedures, and changes; follow existing standards and conventions.
  • Provide high-quality customer service and end-user support, including ticket handling and clear communication with non-technical staff.
  • Coordinate across teams on cross-functional dependencies.

  • Solid grasp of networking fundamentals: VLANs, subnetting, TCP/IP, DHCP, DNS, and switching concepts.
  • Understanding port security concepts and remediation.
  • 5+ years experience administering the customer’s classified VDI / thin-client desktop platform
  • 5+ years experience Windows 10 and/or Windows 11 administration and troubleshooting.
  • Hands-on experience with PXE-based imaging/deployment.
