System Administrator

Insight Global is seeking a TS/SCI System Administrator to support a cutting-edge cyber research and development program. This position is ideal for a well-rounded IT professional who enjoys working across multiple technologies rather than specializing in a single discipline. The team is looking for a highly adaptable “jack-of-all-trades” administrator who can confidently support Windows systems, Linux environments, Cisco networking infrastructure, virtualization platforms, hardware troubleshooting, and general IT operations.

Responsibilities include system administration, provisioning and configuration of servers and workstations, patch management, infrastructure maintenance, troubleshooting complex technical issues, inventory management, and supporting secure classified environments.

The ideal candidate is someone who enjoys solving problems independently and is comfortable working on unfamiliar systems when needed. Successful candidates will be capable of troubleshooting issues across networking, system administration, virtualization, hardware, and operating systems without requiring extensive direction or ramp-up time.

Additional responsibilities may include:

• Supporting Windows and Linux server environments
• Managing VMware-based infrastructure
• Maintaining Cisco networking equipment and security appliances
• Executing and troubleshooting PowerShell and Bash scripts
• Supporting Git and Kubernetes environments from an administrative and maintenance perspective
