Role Overview You’re a seasoned Site Reliability Engineer who loves owning complex infrastructure, making things run faster, safer, and with less manual effort. In this Staff‑level role, you’ll design and operate VMware‑based private cloud platforms that power mission‑critical SaaS products used by customers around the world. You’ll work across Linux, Windows Server, networking, storage, and automation frameworks to increase reliability, reduce toil, and modernize a global datacenter environment. You’ll have the scope to set technical direction, build automation at scale, and mentor engineers while staying hands‑on with VMware vSphere, F5/AVI load balancers, and hybrid Active Directory. Here’s a breakdown of what you’ll do (not all of it, just the important stuff) Lead the architecture, deployment, and ongoing optimization of VMware vSphere–based private cloud infrastructure across multiple global datacenters. Design and build automation using PowerShell/PowerCLI, Ansible, Python, and CI/CD tools to streamline provisioning, configuration, and compliance. Administer, harden, and troubleshoot Linux (RHEL/CentOS/Ubuntu) and Windows Server environments that host enterprise and SaaS workloads. Integrate and manage Active Directory for authentication, access control, and service accounts across hybrid on‑prem and cloud environments. Partner with network and security teams to manage firewalls, VPNs, storage, and load balancers (F5 BIG‑IP, AVI/NSX Advanced Load Balancer) for highly available services. Document architectures and runbooks, participate in on‑call and change management, and mentor engineers while influencing long‑term reliability and automation strategy. These are the essentials you’ll need to get an interview 10+ years of experience in systems or infrastructure engineering, including operating large‑scale enterprise or SaaS datacenter environments. Deep hands‑on expertise with VMware vSphere (ESXi, vCenter, DRS, HA, vMotion, distributed switches) in production. Strong Linux administration skills (RHEL/CentOS/Ubuntu), including performance tuning, system hardening, and advanced troubleshooting. Solid experience with Windows Server and Active Directory (Group Policy, DNS, authentication and access integrations). Proven track record building and maintaining automation using PowerShell/PowerCLI, Ansible, Python, or similar tools, plus familiarity with Git or other version control. Good understanding of storage (SAN/NAS), TCP/IP networking, DNS, VPNs, firewalls, and production monitoring/alerting. A collaborative, problem‑solving mindset with the ability to lead complex incidents, communicate clearly, and operate in an on‑call, high‑availability environment. It would be great if you had these too, but we’ll support you if you don’t Experience with enterprise storage and compute platforms such as Pure Storage or Cisco UCS. Familiarity with Terraform, Jenkins, Azure DevOps, or similar tools for infrastructure as code and CI/CD automation. Exposure to security hardening and compliance frameworks such as CIS benchmarks, NIST, or ISO 27001.
