## Description (the employer's text)

### 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.

### What You Bring

### Required

- Active TS/SCI clearance
- Ability to work fully onsite in Dayton, Ohio
- Hands-on production administration of at least one primary VDI platform:
- AWS WorkSpaces
- Azure Virtual Desktop
- Omnissa / VMware Horizon
- Demonstrated ability to configure, troubleshoot, maintain, or improve enterprise virtual desktop infrastructure
- Working knowledge of Windows infrastructure, identity and access, endpoint management, or related enterprise systems
- Ability to use scripting or automation to improve administration and reduce repetitive work
- Familiarity with security hardening and compliance requirements in regulated, government, or classified environments
- Ability to produce clear technical documentation, operating procedures, and configuration guidance
- CompTIA Security+ or another certification accepted for the program’s required DoD 8140 baseline
### Strong Additional Alignment

You may stand out if you have worked with:

- 10ZiG Manager or comparable thin-client management platforms
- Active Directory and Group Policy
- Virtual desktop image management
- User profile management
- Cloud-based desktop provisioning
