CyberSecurity/SysAdmin

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.
