ABOUT THE OPPORTUNITY

The company is hiring a Virtualization Administrator to provide dedicated operational support for a customer’s enterprise virtualization infrastructure, as part of a long-term project. You will help ensure the stability, security, availability, and continuous improvement of the platform.

This is a hands-on role for someone who is methodical, service-oriented, and quick to learn. You will resolve incidents and requests, implement approved changes, maintain platform health, security, capacity, and lifecycle compliance, and automate routine tasks. You will work independently on assigned operational tasks while following established procedures and change-management controls. Complex, architectural, or high-risk matters are escalated to senior engineers or the Team Lead.

• Work with IT teams, stakeholders, and vendors to plan and deliver virtualization projects under the Team Lead’s guidance.

• Provide timely updates on project progress, issues, and resolutions.

• Guide junior colleagues in established practices.

• Maintain infrastructure and process documentation, and report regularly on platform health, performance, and capacity.

• Provide on-call/standby support on a rotation basis.

• Provide ad hoc support within or beyond the team, including special projects or temporary service-delivery assignments, as requested.

• Hands-on experience applying Infrastructure as Code (IaC) principles with Terraform to provision and manage virtual infrastructure, particularly VMware vSphere resources.

• Proficiency with command-line tools for managing virtualized systems.

• Sound understanding of storage, networking, backup, server hardware, and operating-system dependencies.

• Methodical troubleshooting skills and the ability to resolve incidents with minimal service disruption.

• Ability to follow established procedures and change-management controls.
