• Experience with Azure and Google Cloud Platform (GCP)
• Familiarity with Infrastructure as Code tools such as Terraform or ARM templates
• Experience with Ansible for configuration management and patching automation
• Familiarity with SRE concepts, including SLIs, SLOs, error budgets, toil reduction, and reliability engineering practices
• Exposure to VMware vSphere, ESXi, and vCenter administration
• Exposure to GitLab CI/CD or similar pipelines for infrastructure automation workflows
• Experience with monitoring and observability technologies such as Datadog, OpenTelemetry, Signoz, or equivalent platforms
• Strong written and verbal communication skills, with the ability to create clear technical documentation and operational runbooks
• Relevant certifications such as AZ-104 (Azure Administrator), Google Cloud Associate, VMware VCP, or Ansible equivalent are a plus

Requirements

• Administer and support Windows Server environments across colocation and cloud infrastructure, including provisioning, configuration, upgrades, patching, and day-to-day operational support
• Manage virtual machine lifecycles, including provisioning, resource management, right-sizing, operational health, and decommissioning across on-premises and cloud environments
• Support and maintain infrastructure across colocation facilities and cloud environments, including Azure and GCP
