Job Description

Centurion is currently seeking a Virtualization SME who will provide technical leadership and engineering oversight for the design, implementation, and operation of the enterprise virtualized infrastructure, with a focus on VMware Cloud Foundation (VCF), vSphere, NSX, and hybrid cloud integration. This role serves as the escalation point for complex issues, drives architectural decisions, and ensures the environment is optimized for performance, resiliency, and scalability.

Program Description: Delivers end-to-end IT infrastructure support across all service tiers, including Tier 1 Help Desk, Tier 2 End User Support, and Tier 3 Server, Platform, and Network Engineering. The program provides comprehensive support for hardware, software, and network services; manages incidents, problems, and service requests; maintains continuous infrastructure monitoring and operations; oversees hardware and software lifecycle activities; and ensures coordinated escalation and resolution across all tiers to maintain service continuity and performance.

The environment spans on-premises SDDC infrastructure (compute, storage, network), VCF-based platforms, and cloud services (e.g., Azure/AWS), requiring deep expertise in workload placement, lifecycle management, and hybrid connectivity.

Responsibilities:

• Lead architecture, design, and evolution of VMware-based SDDC environments, including VCF domains, vSphere clusters, vSAN, and NSX networking.
• Plan and execute workload migrations across environments, including data center migrations, adoption, and workload rebalancing.
• Integrate site-to-site recovery strategy using JetStream, including supporting disaster recovery runbooks, tabletops, failover/failback processes, and recovery validation.
• Plan and coordinate VCF lifecycle management activities, including patching, upgrades, and bundle management across domains.
• Lead reoccurring performance and capacity planning across compute, storage, and network layers, ensuring efficient resource utilization and future scalability.
• Design and implement network segmentation and micro-segmentation using NSX, aligned to Zero Trust and security requirements.
• Define and manage infrastructure service offerings, including customization profiles and service catalog capabilities within VCF (or equivalent SDDC abstractions).
• Lead complex troubleshooting across the full stack (compute, storage, network, and virtualization layers), including performance degradation and stability issues.
• Oversee and enhance backup and recovery solutions to ensure data protection, integrity, and availability.
• Establish and maintain automation patterns for provisioning, configuration, and lifecycle management.
• Ensure security and compliance through patching, configuration management, and integration with enterprise security controls.
• Maintain authoritative documentation for architecture, configurations, and operational procedures.
• Provide technical leadership and mentorship to engineering and operations teams.
• Evaluate emerging technologies and recommend improvements to the platform and operating model.

Required Skills:

• Bachelor’s degree in computer science, information technology, or a related field, or equivalent experience.
• 10+ yrs leading virtualization administration.
• Demonstrated experience in leading the management of VMware, Hyper‑V, or similar technologies.
• Must have VCF experience.
• Automating IT administration and server provisioning through tools such as Azure DevOps, Azure Automation, Azure CLI, Bicep, PowerShell, JavaScript, and/or VMWare PowerCLI.
• Integrating infrastructure tool APIs to enable the deployment of Infrastructure as Code integrated with CI/CD deployment pipelines.

Preferred Skills

• Minimum: VMware Certified Professional (VCP)
• Preferred: VMware Certified Advanced Professional (VCAP)
