The role emphasizes automation, operational excellence, and collaboration across engineering, IT support, and operations.

Qualifications

• Bachelor's degree in Engineering, Computer Science, or a related field, or equivalent practical experience.
• 3-6 years of experience in systems administration, infrastructure operations, or cloud operations.
• Strong hands-on experience administering Windows Server environments, including production patching, upgrades, and troubleshooting.
• Experience managing virtual machine infrastructure across on-premises and cloud platforms.
• Experience with a modern monitoring and observability platform; Datadog preferred.
• Proficiency in at least one scripting language such as PowerShell, Python, or Bash.
• Experience operating hybrid infrastructure across colocation or on-premises data centers and public cloud environments.
• Experience with patch management tooling such as Ansible, PatchMyPC, SCCM, or WSUS in a production environment.
• Strong troubleshooting and problem-solving skills across infrastructure, operating systems, and cloud environments.
• 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, SLIs/SLOs, and reliability engineering practices.

Responsibilities

• 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.
• Manage cloud resources including virtual machines, storage, networking, and core platform services.
• Perform system upgrades, patching, and backup operations across cloud and on-premises environments.
• Execute and maintain patch management processes across Windows Server environments, including maintenance windows, patching cadences, and pre- and post-patch validation.
• Respond to security vulnerability findings by triaging, scheduling, and remediating identified exposures in partnership with security teams.
• Monitor system performance, availability, and capacity across cloud and on-premises environments using monitoring and observability platforms.
• Build, tune, and maintain monitors, alerts, and dashboards to improve signal quality, reduce noise, and identify issues before they become incidents.
• Respond to infrastructure alerts and incidents, perform root cause analysis, and implement corrective actions.
• Identify recurring operational issues and use automation or permanent fixes to improve system reliability.
• Build and maintain automation for recurring operational processes such as patching, VM provisioning, health checks, remediation, and reporting.
• Develop scripts and automated solutions using PowerShell, Python, Ansible, or similar technologies to eliminate repetitive operational tasks.
• Integrate automation with monitoring and observability platforms to support automated responses, proactive checks, and self-healing workflows.
• Support Infrastructure as Code practices for repeatable and consistent environment provisioning.
• Create and maintain technical documentation, operational runbooks, and procedural guides.
• Collaborate with development, cloud engineering, IT support, and operations teams to support system integration and service delivery.
• Communicate clearly regarding system status, incident updates, and project progress.
