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.
