Job description

We are seeking a highly skilled Senior Azure Systems Engineer to be responsible for building, operating, and maintaining enterprise-grade system infrastructure natively on Microsoft Azure, as well as managing complex hybrid-cloud environments. This role acts as a bridge between traditional systems administration and modern cloud operations, focus areas including operating system management (Linux/Windows), hybrid connectivity, virtualization, and identity systems within the cloud ecosystem.

Key Responsibilities

• Hybrid Systems Infrastructure: Build and manage scalable architectures linking on-premises systems, legacy datacenters, and edge networks directly to Microsoft Azure using technologies like Azure Arc and ExpressRoute.
• OS & Workload Engineering: Supervise the deployment, configuration, licensing, and security patching of enterprise virtualised infrastructure, including Windows Server and Enterprise Linux distributions running inside Azure compute layers.
• Identity & Directory Services: Manage enterprise identity management fabrics, including Microsoft Entra ID (formerly Azure AD), Entra Domain Services, active directory sync topologies, and role-based access management (RBAC).
• Systems Automation: Eliminate manual administrative tasks by writing robust automation scripts using PowerShell, Azure CLI, and deployment frameworks like ARM templates or Azure Bicep.
• Business Continuity: Architect, routinely test, and maintain enterprise backup topologies and disaster recovery strategies using Azure Backup and Azure Site Recovery (ASR).
• 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.
• Comprehensive understanding of foundational networking concepts (DNS, DHCP, TCP/IP, routing, load balancers, and firewalls).
• Practical expertise scriptwriting in PowerShell or Python to automate repetitive system tasks.
• 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.
• Highly structured system environments where configurations are entirely automated, auditable, and compliant with corporate governance baselines.
• Proactive infrastructure monitoring that traps system anomalies and performance drops before they can impact production workflows.
