Virtualization Patching Engineer

Nutanix Infrastructure Engineer

12-Month Contract | Critical Infrastructure Environment

Help Power a Major Virtualization Transformation

Our client is entering a critical modernization phase, transitioning a highly secure, segmented virtualization environment from VMware toward Nutanix. They're looking for a hands-on Nutanix Infrastructure Engineer who thrives in complex environments, values operational excellence, and enjoys being the calm, steady presence during change.
If you're energized by mission-critical systems, disciplined patching, and solving infrastructure challenges in secure environments, this role offers both impact and depth.

Why This Role Is Interesting

• You'll support critical infrastructure systems where uptime truly matters
• You'll work across both connected and air-gapped (dark site) environments
• You'll help stabilize and modernize a platform during a multi-year VMware-to-Nutanix transition
• You'll combine hands-on technical work with structured change management and stakeholder communication

This is not a "set-and-forget" role-it's for someone who likes owning platform health, understanding system dependencies, and doing things the right way.

What You'll Be Doing

Platform Operations & Stability

• Maintain and support Nutanix clusters in daily operations
• Respond to hardware issues such as disk, DIMM, and drive failures
• Be available to physically visit data centers as needed, especially in the first 30 days
• Support platform stability during patching cycles, where maintenance may surface hardware or component issues

Patching & Lifecycle Management

• Execute Nutanix patching across:
  • Internet-connected environments
  • Dark site (air-gapped) environments
• Perform limited VMware patching in a frozen, maintenance-only environment
• Ensure system uptime, compliance, and patch discipline
• Support long-term vSphere lifecycle milestones through October 2027

Dark Site / Air-Gapped Environment Work

• Operate confidently in environments with no direct internet access
• Use IIS servers and internal repositories to stage and apply approved patches
• Spend time working across both public and dark site environments (roughly 50/50)

Change Management & Communication

• Participate in structured change and maintenance processes
• Clearly communicate risk, plan, and outcomes to stakeholders
• Maintain documentation and follow established operational procedures within a regulated environment

What You Bring

Core Skills (Top Requirements)

• Hands-on Nutanix infrastructure experience
• VMware ESXi and vSphere administration
• Dark site / air-gapped patching experience
• Strong virtualization and clustering knowledge
• Prism (Element & Central)
• SSH
• Experience supporting critical or highly available systems

Nutanix Expertise

• Prism Element storage cluster administration
  • Nutanix AOS 6.10+
  • Prism Element UI
  • SSH usage
• Prism Central administration
• AHV administration
• Nutanix Lifecycle Manager (LCM)
  • Internet-connected and dark site upgrade workflows
  • Coordinated upgrades for AOS, AHV, firmware, Prism, and ESXi
• Nutanix NCC health checks (pre- and post-patch)

VMware / vSphere Experience

• vCenter Server administration
  • Clusters, DRS, maintenance mode, host lifecycle
• vCenter Server patching and upgrades
  • Baselines, version compatibility, validation
• ESXi host patching and upgrades
• Awareness of VMware-Nutanix compatibility across AOS versions and hardware generations

Additional Strengths

• Understanding of hardware dependencies (UEFI vs legacy BIOS, node generations)
• Experience coordinating or supporting hardware repairs
• Comfortable following procedural documentation and test scripts
• Experience with control validation and post-upgrade review
• Strong organization and communication skills

Nice to Have

• Experience in regulated or critical infrastructure environments
• Background in utilities, energy, or highly secure enterprise environments
