Senior Virtualization & Systems Engineer

Role Overview

• Build and configure VMware vSphere clusters from scratch — including ESXi host deployment, vCenter installation, vSAN setup, distributed virtual switches, and HA/DRS policies.
• Plan, rack, cable, and commission physical Windows Server hardware including BIOS/firmware configuration, RAID setup, NIC teaming, and bare-metal OS installation.
• Administer and maintain the VMware environment on an ongoing basis, including VM lifecycle management, host patching, snapshot management, and capacity monitoring.
• Engineer and deploy Active Directory environments including forest and domain design, site and replication topology, FSMO role placement, DNS integration, and OU structure.
• Perform day-to-day Active Directory administration including user and group management, delegation of control, trust relationships, and replication health monitoring.
• Design and implement Group Policy frameworks for security baselines, software deployment, user environment management, and compliance enforcement — and manage ongoing GPO changes and troubleshooting.
• Administer DNS, DHCP, and PKI/certificate services in support of Active Directory and the broader enterprise environment.
• Manage and support Microsoft 365 services including Exchange Online, Teams, and SharePoint, with a focus on hybrid identity and integration with on-premises Active Directory.
• Implement and maintain VMware disaster recovery solutions including vSphere Replication, Site Recovery Manager, and Veeam-based backup strategies; test and validate recovery procedures regularly.
• Monitor infrastructure health across physical servers, virtual hosts, and storage — proactively identifying and resolving performance issues before they impact operations.
• Develop PowerShell scripts and automation to streamline builds, administrative workflows, and recurring operational tasks.
• Produce and maintain engineering documentation including infrastructure diagrams, build runbooks, GPO specs, and DR playbooks.
• Provide Tier 3 escalation support and serve as the subject matter expert across VMware, Windows Server, Active Directory, and Microsoft 365.

Requirements

• 8–10 years of hands-on experience in systems or infrastructure engineering, with a track record spanning both building new environments and administering them long-term.
• Proven experience standing up VMware vSphere clusters from bare metal — ESXi, vCenter, vSAN, distributed switches, and HA/DRS — as well as ongoing vSphere administration.
• Direct experience building Active Directory forests and domains from scratch, combined with strong day-to-day AD administration skills.
• Strong Group Policy experience spanning both initial design and framework build-out as well as ongoing GPO management and troubleshooting.
• Hands-on experience with physical Windows Server hardware: racking, BIOS/iDRAC/iLO configuration, RAID provisioning, NIC teaming, and bare-metal OS deployment.
• Deep proficiency with Windows Server (2016/2019/2022) including AD DS, DNS, DHCP, PKI, DFS, and print services.
• Working knowledge of Microsoft 365 administration including Exchange Online, licensing, tenant configuration, and hybrid connectivity via Azure AD Connect.
• Strong PowerShell scripting skills for both infrastructure automation and routine administrative tasks.
• Solid understanding of networking fundamentals — VLANs, routing, DNS, and firewall rules — as they apply to VMware and Windows environments.
• Experience with enterprise backup and DR platforms such as Veeam, Zerto, or VMware Site Recovery Manager.
• Ability to produce clear technical documentation including build guides, diagrams, and operational runbooks.
• Microsoft Intune experience is a plus. Familiarity with Intune for endpoint enrollment, compliance policies, configuration profiles, and co-management alongside on-prem Group Policy is highly desirable.
• Bachelor's degree in Computer Science, Information Technology, or a related field or equivalent professional experience.
