• Performance Operations: Monitor OS-level performance, troubleshoot deep system bottlenecks, manage enterprise logging via Log Analytics, and configure alerts through Azure Monitor.

Requirements

• Experience: 5+ years of systems engineering experience, with at least 3+ years architecting and supporting enterprise systems workflows in Microsoft Azure.
• Core Technical Skills: Deep, production-grade knowledge of core server operating systems (Windows Server, Red Hat, Ubuntu) and advanced troubleshooting methodologies.

• Platform Proficiencies: Proven track record deploying core Azure IaaS components (Virtual Machines, Managed Disks, Virtual Networks, Key Vault, and Blob Storage).
• Certifications: Active Microsoft Certified: Azure Administrator Associate or Microsoft Certified: Azure Solutions Architect Expert designations are highly desirable.
• Modernized, reliable server infrastructure operating with 99.99% uptime across both cloud and hybrid environments.
