• Performing system patching, upgrades, and lifecycle management.
• Installing, configuring, and maintaining simulation software and supporting middleware.
• Supporting distributed training environments connecting multiple training sites.
• Configuring and maintaining application servers supporting LVC exercises.
• Ensuring systems are properly synchronized and configured for large‑scale training events.
• Implementing and maintaining RMF controls and STIG compliance.
• Conducting vulnerability remediation and security hardening.
