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

Job description

Join Our Team

Devis is a leading provider of innovative software development, management, and consulting services, specializing in cutting-edge technologies such as DevSecOps, AI, and Machine Learning. With over 30 years of experience, we have established ourselves as a trusted partner for government agencies, delivering tailored, mission-critical solutions that drive digital transformation and operational excellence. Our client-centric approach, coupled with our deep domain expertise and technical prowess, enables us to forge enduring relationships and consistently deliver high-impact, adaptive solutions that resonate with the unique needs of the public sector.

The Role

This is the senior technical seat on the helpdesk team supporting a federal agency. Incidents reach you after Tier 1 and Tier 2 have tried and could not close them, so the work is root-cause analysis and systems administration rather than ticket triage. You support about 2,100 people at headquarters in Washington, DC and 53 field offices nationwide; field IT staff upgrade to your team when local troubleshooting runs out.

The environment is Microsoft end to end: Microsoft 365, Azure, and Entra ID for productivity and identity; Intune and ManageEngine Endpoint Central for endpoint management and patching; Microsoft Defender for endpoint protection; Windows Server and SUSE Linux Enterprise Server behind the scenes. The desktop fleet is HP EliteBook and Lenovo ThinkPad hardware imaged to the U.S. Government Configuration Baseline (USGCB), and the ticketing system is Zendesk. An enterprise migration to Windows 11 runs during the contract, and you are the technical lead for its planning, application testing, configuration, and deployment.

What You'll Do

• Take the incidents nobody else could close: advanced troubleshooting, root-cause analysis, and the judgment call on whether an incident is a 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

What You'll Need

• A bachelor's degree in information technology, computer science, information systems, or a related field, 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

Nice to Have

• A Microsoft role-based certification such as Endpoint Administrator, Azure Administrator, or Microsoft 365 Administrator
• ITIL v4 Foundations
• A Windows 10 to Windows 11 enterprise migration you helped deliver
• Prior support to a federal civilian agency, particularly a small one
• Experience supporting assistive technology (the environment includes JAWS, Fusion, Dragon, ZoomText, and Duxbury Braille)
• Comfort with a legacy estate alongside the modern stack: the inventory includes Oracle 11G, HP-UX, PowerBuilder, Kofax, and Livelink
• SUSE Linux Enterprise Server administration

Location, Schedule, and Logistics

• Standard schedule is an eight-hour day scheduled between 7:00 a.m. and 7:00 p.m. Eastern, Monday through Friday, excluding federal holidays. Occasional weekend work may come up with advance government approval
• On-site at agency headquarters in Washington, DC (NoMa area, Metro-accessible). Telework is by exception only and requires government approval
• You will work on a government-furnished laptop. Personal devices cannot connect to the agency network
• At least 40 hours per year of paid professional training in your core skill areas, at no cost to you
• Occasional travel to agency field offices, reimbursed at federal travel rates
