Key Responsibilities

As Senior Virtualization Engineer, you have deep hands-on expertise in Proxmox VE and Nutanix (AOS/AHV), and strong VMware knowledge, to lead platform assessment and migration of VMware workloads to Nutanix and/or Proxmox. You will own day-to-day platform engineering tasks across assessment, migration planning & execution, and Day-2 operational stabilization, working closely with a cross-functional team of infrastructure, network, security, and application owners.

Lead technical assessment of current VMware estate (inventory, dependencies, criticality, constraints) and define target architecture for Proxmox and/or Nutanix.

Define success criteria, test plans and validation steps across compute, storage, network, backup/DR, monitoring, and security.

Build and configure lab/PoC environments (clusters, storage, networking, management tooling) and document findings and recommendations with risks and trade-offs.

Design migration waves, cutover approaches, validation steps, and rollback plans; coordinate change approvals and maintenance windows.

Execute workload migrations from VMware to Nutanix AHV and/or Proxmox (VM conversion, network/storage mapping, guest OS readiness, post-migration verification).

Troubleshoot migration issues across hypervisor, storage, network, and guest OS layers; drive problem resolution to closure.

Establish operational runbooks and standards: patch/upgrade process, backups, DR tests, monitoring/alerting, capacity/performance management, and incident response.

Ensure high availability and resiliency configuration (cluster HA, live migration, storage redundancy); perform failover and recovery drills.

Produce documentation and deliver knowledge transfer to internal teams (admin guides, SOPs, architecture diagrams).

Automate provisioning and configuration where feasible (Ansible/IaC; scripting) and standardize templates for VM builds.

Integrate with enterprise services (directory services, DNS/DHCP, NTP, PKI) and align security hardening requirements.

Work with application owners to plan migrations, validate functionality and performance, and minimize downtime.

Communicate progress, risks, and decisions clearly to stakeholders; contribute to project status and technical documentation.
