Senior Server Engineer

This is a rare chance to join a tenured, low-turnover infrastructure team at a globally recognized, multi-billion dollar organization with a worldwide footprint and thousands of employees across multiple continents. Their on-premises environment is the backbone of global operations and this team is at the center of it all. The organization is making serious investments in modernizing their enterprise infrastructure, with hands‑on AI and automation initiatives actively in flight.

The technology stack here is genuinely exciting, the team culture is built on curiosity and collaboration, and your contributions will be visible from day one.

Engineers who thrive here are intellectually curious, leave ego at the door, and are energized by complexity. If you want to be challenged technically, supported in your growth, and surrounded by real professionals - this is it.

As a Senior Infrastructure Engineer, VMware vSphere/ESXi will be the heartbeat of your day‑to‑day work. You'll own the health, performance, and scalability of a large‑scale virtualization platform while also contributing across a modern, evolving stack that includes Kubernetes, Docker, Red Hat, Ansible automation, Active Directory, and Azure IaaS. On‑call rotation runs every 8 weeks, with monthly maintenance windows typically after hours or on weekends.

One thing that sets this role apart: you need to be genuinely strong in both Windows and Linux. This environment runs a large‑scale mixed OS footprint, and you'll be expected to diagnose and resolve issues across both platforms with equal confidence. On the Windows side, that means Windows Server (2016+), Active Directory, Group Policy, and Power Shell. On the Linux side, you need to be comfortable at the command line including RHEL/Ubuntu, user management, permissions, disk, services, and SELinux.

Candidates who are Windows‑only or Linux‑only will not be the right fit for this team.

• Own the health, performance, and scalability of a sprawling VMware vSphere/ESXi virtualization platform — this is where you'll spend the majority of your time.
• Troubleshoot host failures, DRS/HA events, and distributed vs. standard switch configurations with confidence and speed.
• Support vMotion operations and contribute to capacity planning and platform optimization across the virtualization layer.
• Get hands‑on with a modern, evolving tech stack that includes Kubernetes, Docker, and Red Hat container platforms powering real AI workloads.
• Support containerized environments in production and contribute to the infrastructure underpinning active automation and AI initiatives.

• Keep a large‑scale Windows and Linux environment running smoothly, diagnosing everything from authentication failures and access issues to full system outages.
• Manage Windows Server (2016+) environments and support RHEL/Ubuntu systems at the command line — including user management, permissions, disk, services, and SELinux.

• Build and maintain automation that actually reduces toil — writing and refining Ansible playbooks through Ansible Tower to streamline provisioning and configuration at scale.
• Leverage Power Shell scripting for task automation and operational efficiency across the Windows environment.

• Manage identity and access infrastructure including Active Directory, Group Policy, DNS, DHCP, and Certificate Services across a complex, multi‑region environment.
• Maintain security and compliance through proactive vulnerability remediation, patch management, and performance monitoring.
• Use enterprise tooling including SCCM for software deployment and change management, and SCOM for infrastructure monitoring to keep the environment healthy and compliant.
• Leverage Zabbix and other monitoring platforms to maintain visibility across a large, distributed infrastructure.
• Play a supporting role in Azure IaaS operations (VMs, RBAC, backup, and disaster recovery) as a complement to the core on‑prem workload.

• Step up during on‑call windows (rotating every 8 weeks) and monthly maintenance windows to keep…
