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
