Virtualization Patching Engineer

Overview

Our client is seeking a Nutanix Infrastructure Engineer for a 12-month contract to support and stabilize a highly segmented virtualization environment during a critical infrastructure modernization initiative.

Patching & Lifecycle Management

• Execute Nutanix patching across both internet-connected and dark site environments
• Perform limited VMware patching (environment is largely frozen and maintenance-only)
• Maintain platform uptime, security, and compliance through disciplined lifecycle management
• Support ATC's VMware/vSphere lifecycle timeline through October 2027
• Validate system health before and after upgrades to ensure successful completion

Dark Site / Air-Gapped Environment Support

• Operate within enhanced security environments with no direct internet access
• Utilize internal IIS servers and approved repositories for sourcing and applying patches
• Effectively support a 50/50 split between public and dark site infrastructure
• Follow strict procedural and control requirements in secure domains

Change Management & Communication

• Participate in structured change management and maintenance window planning
• Communicate risk, status, and outcomes clearly to technical and non-technical stakeholders
