Automation and optimization are essential in this position. You’ll develop and maintain PowerShell scripts to reduce manual work, support backup validation and recovery efforts aligned with COOP requirements, and assist in maintaining virtualized environments such as Nutanix.

 

This role requires strong collaboration with cross-functional teams to troubleshoot system dependencies, resolve connectivity issues, and maintain clear documentation for configurations and procedures. You’ll also continue to build your technical expertise in Windows systems, Active Directory, and enterprise management tools to support ongoing mission needs.
