Systems administrators recruiting
Systems administrators keep the servers, directories, storage, virtualization platforms and core services running, patched and compliant.
On cleared programs the role often sits inside a classified environment where the administrator is one of the few people with privileged access, which is why these requisitions carry a clearance line and a certification line together. Recruiters Workforce recruits Windows, Linux and virtualization administrators for defense, intelligence, civilian and commercial environments.
What systems administrators do
The daily work is provisioning and patching servers, managing Active Directory or other identity services, administering virtualization and storage, backups and recovery, monitoring, and applying the security technical implementation guides and scan findings a program's authorization requires. Administrators on classified programs also handle media controls and the account management that accreditation demands. Many programs now expect scripting in PowerShell, Bash or Python and familiarity with configuration management.
Requisitions name the operating systems and platforms, the scale of the estate, whether the role is inside a classified environment, and whether it includes on-call or shift coverage.
Certifications commonly requested
Administrator requisitions pair a platform credential with Security+, and the issuing bodies describe the credentials below.
- CompTIA Security+
- Named on nearly every Department of Defense administrator requisition because of the privileged access the role holds. Current version V7; V8 expected on or around November 17, 2026.
- Red Hat Certified System Administrator
- Earned by passing the performance-based EX200 exam; Red Hat recommends the RH124 and RH134 courses or equivalent experience. The standard Linux credential on defense programs.
- Microsoft Certified: Azure Administrator Associate
- Earned through exam AZ-104, a 100-minute proctored exam renewed every twelve months. Requested where the estate includes Azure or hybrid identity.
- ITIL 4 Foundation
- A 40-question, 60-minute multiple choice exam with a 65 percent pass mark and no prerequisites. Requested by programs that run formal change and incident management.
- CompTIA Network+
- Exam code N10-009. Requested where the administrator also supports the local network.
Clearance levels commonly required
Because administrators hold privileged access, defense programs require Secret at minimum and Top Secret for many, and administrators who work inside a SCIF need TS/SCI. Civilian agency positions are high-risk Public Trust. Commercial positions require no clearance. Administrators are among the most frequently sponsored candidates, because a contractor can start a Secret investigation on a strong commercial administrator and place them on unclassified work while it runs.
Engagement models that fit
Administrator seats on task orders suit contract staffing and contract-to-hire, and programs with approved headcount hire directly. Retained search is uncommon for this specialty. The engagement models page compares them.

Questions about recruiting systems administrators
Which certification pairs with Security+ on an administrator requisition?
A platform credential: Red Hat's RHCSA for Linux estates, Microsoft's Azure Administrator Associate for Windows and hybrid estates, and ITIL 4 Foundation where the program runs formal service management. The contract usually names the pairing, and the requisition summary should repeat it.
Can an administrator with a lapsed clearance be placed on a cleared program?
Often, if the eligibility remains current and the investigation is in scope, or continuous vetting enrollment was in place, because the NISPOM allows access to be restored on the cognizant security agency's guidance after a break in access or employment. The submittal records the month access ended and the investigation date so that the security office can confirm the position.
