Senior System Administrator – Windows/Azure & Scripting (Federal)

Devis; Washington (District of Columbia); On-site; USD 90,000 - 120,000; Full time

Job summary

Devis is seeking a senior technical helpdesk lead to support a federal agency at headquarters in Washington, DC and field offices. The role focuses on root-cause analysis and system administration, not ticket triage, spanning Microsoft 365, Azure, Entra ID and endpoint management.

You will guide the Windows 11 migration, harden workstations, assist security, and document remediation steps in Zendesk, ensuring agency applications stay functional under USGCB baseline.

Qualifications

• Bachelor's degree in information technology, computer science, information systems, or ten years of relevant professional experience in place of the degree.
• Hands-on system administration in a Microsoft enterprise environment, including Active Directory, Entra ID, and Microsoft 365.
• PowerShell scripting you have written and shipped, not just edited.
• Endpoint management and patching experience with Intune, ManageEngine Endpoint Central, or comparable tooling.
• Experience serving as the escalation point above Tier 1 and Tier 2 support.
• Clear written documentation habits.

Responsibilities

• Take escalated incidents: advanced troubleshooting, root-cause analysis, and determine if issues are one-off or the first sign of a system-wide problem.
• Administer Active Directory, Azure, Entra ID, and Microsoft 365: accounts, group policy, permissions, and access controls.
• Write, build, and deploy PowerShell scripts to automate builds, deployments, and routine work across multiple environments.
• Install, update, and patch applications across the enterprise; author and test install scripts; package and integration-test applications.
• Plan and deliver the Windows 11 migration, keeping every agency application working under the USGCB desktop baseline.
• Harden workstations, monitor threats, and work with the agency security operations team on virus scans, malware remediation, and desktop data recovery.
• Support Microsoft 365 products including SharePoint, OneDrive, Teams, and Power Apps, plus mobile device configuration.
• Monitor network performance and troubleshoot connectivity across LAN and WAN infrastructure.
• Document your work in Zendesk thoroughly enough that another technician or analyst can pick it up without you in the room
