Staff Site Reliability Engineer

We are seeking a highly skilled Staff Site Reliability Engineer with deep technical expertise across VMware, Linux, and automation frameworks, to join our global Infrastructure & Operations team.

The ideal candidate will have extensive experience operating in enterprise datacenter environments, a strong foundation in Microsoft Active Directory and Windows Server, and a proven ability to build—not just run—automation workflows that improve reliability, scalability, and efficiency.

You will work closely with other engineering teams (Network, Security, SRE, and DevOps) to ensure the stability and performance of our global platform and drive continuous improvement through automation and infrastructure modernization.

Key Responsibilities

• Architect, deploy, and maintain VMware-based private cloud infrastructure across multiple global datacenters.
• Automate infrastructure operations using PowerCLI, Ansible, Python, or other automation tools to streamline provisioning, configuration, and compliance tasks.
• Administer and optimize Linux (RHEL/CentOS/Ubuntu) and Windows Server operating systems supporting enterprise workloads.
• Integrate and maintain Active Directory for authentication, policy, and service account management across hybrid environments.
• Collaborate with network and security teams to manage and troubleshoot firewall rules, VPNs, load balancers, and routing dependencies.
• Support and maintain F5 BIG-IP and AVI (NSX Advanced Load Balancer) for application delivery and traffic management.
• Ensure system availability, performance, and security to meet SLAs and compliance requirements (CIS, NIST, ISO).
• Participate in on-call rotations and change control processes for infrastructure incidents and maintenance.
• Document architecture, procedures, and automations for cross-team knowledge sharing and operational continuity.
• Mentor junior engineers and contribute to long-term technical strategy for infrastructure automation and modernization.

Required Experience/Skills

• 10+ years of experience in systems engineering or infrastructure roles, with at least 5 years at a senior or staff level.
• Expert proficiency in VMware vSphere (6.x/7.x/8.x) – including ESXi, vCenter, DRS, HA, vMotion, and distributed switches.
• Advanced Linux administration skills (RHEL/CentOS/Ubuntu), including performance tuning, system hardening, and troubleshooting.
• Strong understanding of Windows Server and Active Directory, including Group Policy, DNS, and authentication integrations.
• Demonstrated experience building automation frameworks using PowerShell, PowerCLI, Ansible, Python, or similar tools.
• Hands-on experience in enterprise datacenter environments, including storage (SAN/NAS), networking, and monitoring systems.
• Solid understanding of TCP/IP networking, email infrastructure, DNS, VPNs, and firewall concepts.
• Experience working with F5 BIG-IP, AVI / NSX Advanced Load Balancer, or similar ADC platforms.
• Familiarity with configuration management, version control (Git), and CI/CD pipelines.
• Strong problem-solving and analytical skills with a focus on reliability and scalability.

Nice to Have

• Knowledge of Pure Storage, Cisco UCS, or similar datacenter technologies.
• Experience with Terraform, Jenkins, or Azure DevOps for infrastructure automation.
• Exposure to security hardening and compliance frameworks (CIS, NIST, ISO 27001).
• Experience in SaaS or highly available enterprise environments.
