Terraform/PowerShell beneficial).- Backup/restore and DR concepts;
experience integratingplatforms with enterprise backup tooling (e.G., Veeam).- Solid understanding of datacenter networking and storage fundamentals (DNS/DHCP/NTP, TCP/IP, firewalls, iSCSI/NFS, multipath).- Robust documentation, troubleshooting and stakeholder communication skills;
able to work independently in a contractor capacity.Key ResponsibilitiesAs 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.- Work as part of a global team and capability to travel globally (up to 5% of the time) to support- engineering activitiesSkill RequirementsOther Requirements
