Senior Server and Virtualization Engineer

Our client is looking to bring on a Sr. Server Engineer, focused on infrastructure and virtualization. This is a rare chance to join a tenured, low-turnover infrastructure team at a globally recognized, multi-billion dollar organization with thousands of employees across multiple continents.

Their on-prem environment is the backbone of global operations and this team is at the center of it, with serious modernization investments and hands-on AI and automation initiatives actively in flight. Engineers who thrive here are intellectually curious, leave ego at the door, and are energized by complexity.

This team sits onsite in their downtown office, 3 days a week in the office. This person must be willing to do a hybrid schedule along with committing to an on-call rotation every 8 weeks (monthly maintenance windows are typically after hours or weekends).

What You'll Do

• Own a sprawling VMware vSphere/ESXi platform; troubleshooting host failures, DRS/HA events, and switch configurations; supporting vMotion, capacity planning, and optimization.
• Support Kubernetes, Docker, and Red Hat container platforms powering real AI workloads in production
• Keep a large Windows and Linux environment healthy; Windows Server (2016+), AD, Group Policy, and PowerShell on one side; RHEL/Ubuntu command-line work (users, permissions, disk, services, SELinux) on the other
• Build automation that reduces real toil; Ansible playbooks through Ansible Tower, plus PowerShell scripting
• Manage identity and network services: Active Directory, Group Policy, DNS, DHCP, and Certificate Services across a multi-region environment
• Maintain security and visibility through patching, vulnerability remediation, and enterprise tooling (SCCM, SCOM, Zabbix)
• Support Azure IaaS operations (VMs, RBAC, backup/DR) as a complement to the core on-prem workload
• Participate in on-call and after-hours maintenance windows - this is a global environment and uptime is non-negotiable

Required

• 5+ years of enterprise infrastructure engineering, ideally in environments running thousands of servers
• Deep, hands-on VMware vSphere/ESXi expertise - troubleshooting, optimizing, and scaling with confidence. This is the cornerstone of the role.
• Solid Windows Server (2016+) experience and Linux (RHEL/Ubuntu) command-line fundamentals - BOTH REQUIRED
• Working knowledge of DRS, HA, distributed vs. standard switches, and vMotion in production
• Production experience with Kubernetes, Docker, and Red Hat container technologies
• Hands-on Ansible experience including writing playbooks, not just running them
• Strong AD fundamentals across DNS, DHCP, Group Policy, and Certificate Services
• PowerShell scripting and familiarity with enterprise monitoring (SCOM, Zabbix, SCCM)
• A collaborative, curious, coachable presence

Preferred

• Cisco UCS (B- or C-Series); this is a real data center with physical hardware
• Hyper-V or Nutanix familiarity
• Working Azure IaaS understanding; enough to support and troubleshoot, not architect
• Degree optional; what you've built matters more than where you studied
