• Lead or contribute to automation and scripting initiatives using Ansible, PowerShell, Bash, Python, or similar orchestration tools to improve operational efficiency and reduce manual effort.
• Ensure availability, performance, resilience, and recoverability of production environments through proactive monitoring, maintenance, and capacity planning.
• Act as a key responder for Critical and Major production incidents, driving end‑to‑end restoration, root cause analysis, remediation, and post‑incident reviews.
• Support application deployments and collaborate closely with application, database, middleware, storage, network, and security teams.
• Develop and deliver operational metrics, dashboards, and KPIs across infrastructure platforms, providing actionable insights to leadership.
• Drive platform standardization, best practices, and continuous improvement initiatives across distributed environments.
• Serve as a technical escalation point and mentor for engineers across Linux and platform operations teams.

Qualifications include:

Talents needed for success include:

• Strong hands-on experience administering enterprise-scale Windows environments, including Windows Server 2016/2019/2022, in large, regulated enterprises.
• Deep expertise in Windows OS and core platform services, including Active Directory, Group Policy, DNS, DHCP, clustering, networking, storage, and file system management.
• Proven experience supporting mission-critical, high-availability Windows platforms within regulated and highly controlled environments.
• Strong knowledge of ITIL processes, including Incident, Problem, Change, and Release Management, with demonstrated operational discipline.
• Demonstrated leadership in driving and resolving Critical and Major production incidents, coordinating across infrastructure, application, and security teams.
• Proficiency in automation and scripting using PowerShell, with experience integrating automation into operational workflows (patching, remediation, provisioning, and compliance).
• Strong understanding of virtualization technologies (VMware ESXi or equivalent) and Windows virtual infrastructure operations.
• Experience supporting cloud and hybrid environments, preferably AWS, with Windows-based workloads and integrations across on‑prem and cloud platforms.
