Surge support, through January 15, 2027.(possible extension)

This is a surge support position through January 15, 2027. Extension is possible but not guaranteed. The role is hybrid, with on-site work in Washington, DC, supporting a federal client and requires an active public trust or higher clearance.

Sikich is seeking a Systems Administrator to support endpoint management, software deployment, and vulnerability remediation at a federal client. This role will handle day-to-day triage and research around failed deployments, patch and update troubleshooting, end-user coordination, and escalation of recurring technical issues. The ideal candidate is an entry-to-mid level administrator with strong hands-on troubleshooting skills, is comfortable working directly with users, and has the aptitude to grow into broader SCCM, Intune, Azure, and vulnerability management responsibilities.

Prior experience with every listed tool is not required; demonstrated technical curiosity, sound judgment, and willingness to learn are highly valued.

This role supports a federal client environment and requires professionalism and empathy when coordinating with end users, documenting troubleshooting steps, and following established change, security, and escalation procedures.

Activities include, but are not limited to, the following:

• Research vendor vulnerability fixes, release notes, knowledge base articles, and remediation guidance across multiple software products to support testing, packaging, and deployment.
• Triage failed software installs and deployments by reviewing deployment status, client logs, device health, network connectivity, and user-reported symptoms.
• Conduct end-user outreach, coordinate remote troubleshooting sessions, and communicate next steps clearly while minimizing disruption to the user's workday.
• Perform manual software installation, repair, or reinstallation when automated deployment fails, and document the resolution path for future automation or escalation.
• Review logs such as Splunk Windows Event Viewer, Defender, Purview and endpoint management logs to identify root cause, distinguish user-specific issues from device-wide issues, and recommend the next troubleshooting or escalation step.

Document troubleshooting steps, findings, resolutions, and escalation details in the ticketing system so recurring issues can be tracked and knowledge can be reused by the team.

Track remediation progress for assigned devices or software titles, follow up on failed or incomplete deployments, and help maintain visibility into patch compliance status.

• Must possess an active public trust or higher government issued clearance.
• 4-year degree or 4 years of relevant experience in lieu of degree
• Must be willing to work onsite 2-3 days a week.
• Empathy, patience and professionalism when working directly with end users, including the ability to explain technical steps clearly over remote sessions.
• Sound judgment to ask for help, appropriate escalation of issues, and the ability to provide enough technical detail for senior administrators to act quickly.
• Basic Excel proficiency for tracking device lists, remediation status,…
