This is a remote position.

• Operate NSX day to day, including segments, distributed firewall policy, gateways, load balancing, and troubleshooting east-west and north-south traffic.
  
• Manage ESXi host, vCenter, and vSAN lifecycle including patching, firmware alignment, certificate management, and capacity planning.
  
• Diagnose and resolve performance and availability problems across compute, storage, and the virtual network, and drive them to root cause.
  
• Serve as technical lead during platform-level incidents, coordinating with clients, internal teams, and Broadcom or hardware vendor support.
  
• Administer KVM-based or Hyper-V environments where clients run them, and support workload migrations between hypervisors.
  
• Automate recurring operations work using scripting and the vSphere and NSX APIs.
  
• Write formal root cause analyses, execute changes through structured change management, and maintain documentation of baselines, designs, and tuning decisions.
  
• Lead technical delivery of virtualization projects including upgrades, consolidations, and migrations.
  
• Give client stakeholders clear status reporting and practical capacity and best-practice guidance.
  
• Mentor junior engineers and work with storage, network, and service desk teams so the platform fits the wider environment rather than sitting beside it.

• MUST BE fluent in English
  
• Hands-on administration of VMware Cloud Foundation 9 or vSphere Foundation 9 including NSX, or deep vSphere 8 administration (ESXi, vCenter, HA and DRS, vMotion, distributed switches, vSAN) with the aptitude to certify on VCF 9 in your first year.

• Solid understanding of the storage and networking layers beneath virtualization, including shared storage protocols, VLANs, MTU, routing, and multipathing.
  
• Automation ability using AI tooling, scripting (PowerCLI, Python, or an equivalent), and direct work against platform APIs.
  
• Experience writing formal root cause analyses and working inside a structured change management process.
  
• Clear client-facing communication and the ability to work independently across many client environments at once without losing track of any of them.
  
• Prior MSP or other multi-client experience, ideally supporting several customer environments at once.
  
• Associate's or bachelor's degree in information technology or a related field, or equivalent hands-on experience.

• Hands-on experience administering a KVM-based platform or Microsoft Hyper-V with Failover Clustering.
  
• Experience with VMware Aria Operations or similar for capacity and performance management, and with hyper-converged hardware such as Dell VxRail or PowerFlex.
