Systems Administrator (VDI) — TS/SCI

Location: Dayton, OH

Work Model: Fully onsite

Clearance: Active TS/SCI

Build, Secure, and Improve Mission-Critical VDI

Rackner is hiring Systems Administrators to help operate and improve a secure Virtual Desktop Infrastructure and endpoint environment supporting a national-security mission in Dayton, Ohio.

You’ll work hands-on with production virtual desktops, cloud infrastructure, thin-client endpoints, automation, security hardening, and complex troubleshooting in a classified environment.

This is not a traditional desktop-support position. You’ll work across the infrastructure behind secure virtual desktop delivery—including cloud-hosted desktops, identity, endpoint management, automation, security controls, and platform reliability.

For someone who already has VDI depth, this role offers the opportunity to broaden your technical range across:

Multi-cloud VDI
Secure enterprise infrastructure
Endpoint management
Automation and scripting
Cybersecurity compliance
Classified systems operations

Rackner also supports professional certifications aligned with current and future technical work across cloud, cybersecurity, DevSecOps, infrastructure, and related engineering disciplines.

You do not need every technology listed below. We’re looking for strong hands-on depth in the platforms you have actually operated.

Your Impact

Administer and troubleshoot enterprise VDI environments using AWS WorkSpaces, Azure Virtual Desktop (AVD), and/or Omnissa Horizon
Build and optimize desktop images, applications, user profiles, host pools, and scaling configurations
Configure and operate 10ZiG or comparable thin-client and endpoint-management environments
Diagnose and resolve performance, authentication, profile, connectivity, compatibility, and user-access issues
Automate recurring administration using PowerShell, Bash, Python, or similar scripting tools
Harden and secure virtual desktops, Active Directory, endpoints, and cloud resources using DISA STIGs and applicable security controls
Deploy and maintain endpoint configurations, firmware, certificates, security patches, and device settings
Partner with security and infrastructure teams on continuous monitoring, authorization activities, configuration validation, and technical evidence collection
Test and improve VDI performance, reliability, compatibility, and usability
Document system configurations, operating procedures, troubleshooting guidance, technical decisions, and architecture

Where You May Fit

We’re building complementary technical coverage across the team.

Strong alignment may include:

10ZiG + AWS WorkSpaces

10ZiG + Azure Virtual Desktop

AWS WorkSpaces + Horizon

Azure Virtual Desktop + Horizon

Depth in one of these areas matters more than checking every box.

Candidates without direct 10ZiG knowledge may still be relevant if they bring strong thin-client, endpoint-management, or enterprise VDI administration depth.
