Core Responsibilities

Primary Functions

Architect, deploy, and meticulously manage the enterprise-level virtual infrastructure, primarily utilizing VMware vSphere (ESXi, vCenter) and/or Microsoft Hyper-V.
Conduct daily health checks and performance monitoring of the entire virtual ecosystem to proactively identify and address potential issues before they impact business operations.
Serve as the primary escalation point for troubleshooting and resolving complex issues related to hypervisors, virtual machines, virtual networking, and underlying storage.
Administer and optimize Storage Area Networks (SAN) and Network Attached Storage (NAS) environments, ensuring seamless and high-performance connectivity to virtual hosts.
Develop, maintain, and enhance automation scripts using PowerShell, PowerCLI, or Python to streamline repetitive administrative tasks, virtual machine provisioning, and reporting.
Lead capacity planning and forecasting initiatives, analyzing current usage trends to predict future compute, storage, and network resource requirements.
Implement, test, and manage robust disaster recovery and business continuity solutions, such as VMware Site Recovery Manager (SRM) and vSphere Replication, to meet RTO/RPO objectives.
Plan and execute scheduled maintenance, including patching, security updates, and firmware upgrades on ESXi hosts and related hardware to mitigate vulnerabilities and ensure system stability.
Create and maintain comprehensive, detailed documentation for all system configurations, standard operating procedures, and troubleshooting guides to facilitate knowledge sharing and team efficiency.
Collaborate closely with networking, storage, security, and application development teams to ensure new and existing services are seamlessly integrated into the virtual environment.
Enforce and enhance the security posture of the virtual infrastructure by implementing security best practices, system hardening guidelines, and access control policies.
Manage the complete lifecycle of virtual machines, including the creation of standardized templates, provisioning, snapshot management, performance tuning, and secure decommissioning.
Evaluate emerging virtualization technologies, containerization platforms (like Docker/Kubernetes), and hybrid cloud solutions to recommend improvements and drive innovation.
Provide expert-level (Tier 3) technical support and act as a subject matter expert for all incidents, problems, and service requests related to the virtualization platform.
Configure and manage complex virtual networking components, including standard and distributed virtual switches (vDS), VLANs, and network security policies.
Utilize advanced monitoring tools, such as vRealize Operations (vROps), to analyze performance metrics, diagnose bottlenecks, and optimize resource allocation across the environment.
Lead and participate in critical infrastructure projects, from initial requirements gathering and solution design to implementation, testing, and operational handover.
Oversee enterprise backup and recovery solutions (e.g., Veeam, Commvault), ensuring the integrity of virtual machine backups and performing regular recovery drills.
Manage user roles and permissions within the virtualization management console, adhering to the principle of least privilege to maintain a secure administrative environment.
Investigate and resolve performance degradation issues by analyzing I/O, CPU, memory, and network utilization on both the host and guest OS levels.

Secondary Functions

Support ad-hoc data requests and exploratory analysis related to infrastructure performance and capacity.
Contribute to the organization's broader infrastructure strategy and technology roadmap.
Collaborate with business units and application owners to translate their needs into technical infrastructure requirements.
Participate actively in sprint planning, daily stand-ups, and other agile ceremonies if the team follows an agile methodology.
