Job Summary

Job Description:
Title: Azure Local (HCI) & AKS Arc Cluster - Senior Administrator

About the Role:
Looking for a hands-on infrastructure engineer to own the build, lifecycle management, and hardening of Azure Local (Azure Stack HCI) clusters running Arc-enabled Kubernetes (AKS). This role sits at the intersection of on-premises hyperconverged infrastructure and hybrid cloud management — deploying 2+ node HCI clusters, standing up AKS on top of them via Azure Arc, and ensuring the resulting platform is production-ready, monitored, and documented to enterprise standards, including Post-Implementation Review (PIR) documentation for client and internal engagements.

Key Responsibilities

Key Responsibilities

Design, build, and validate Azure Local (Azure Stack HCI) clusters (2-node and larger) including storage spaces direct (S2D), networking (SET switches, RDMA/RoCE or iWARP), and cluster witness configuration.
Deploy and manage Arc-enabled Kubernetes (AKS Arc) clusters on top of Azure Local, including node pool sizing, CNI selection, and integration with Azure Arc for centralized policy and monitoring.
Own end-to-end cluster lifecycle: initial deployment, patching/updates via Lifecycle Manager, scaling, and decommissioning.
Configure hybrid identity and access — integrating Azure Arc resources with Microsoft Entra ID (Azure AD) and applying RBAC/Azure Policy consistently across on-prem and cloud resources.
Build and maintain monitoring and alerting for HCI and AKS Arc workloads using Azure Monitor, Container Insights, and relevant Log Analytics workspaces.
Write and maintain Standard Operating Procedures (SOPs), build runbooks, and Post-Implementation Review (PIR) documentation for every cluster deployment or major change.
Automate deployment and configuration tasks using PowerShell, Azure CLI, Bicep/ARM templates, or Terraform; integrate with CI/CD pipelines (GitHub Actions) where applicable.
Troubleshoot cluster, storage, and networking issues across the HCI stack and the Kubernetes control/data plane, engaging Microsoft support where needed.
Collaborate with client-facing infrastructure and DevOps teams to translate requirements into HCI/AKS architecture and capacity plans.
Support security hardening and compliance activities — patch cadence, vulnerability remediation, and access reviews across the HCI/AKS estate.

Skill Requirements

Required Skills & Experience

4-9 years in enterprise infrastructure/systems engineering, with at least 2 years of hands-on Azure Stack HCI / Azure Local deployment and operations.
Working knowledge of Kubernetes fundamentals (pods, deployments, services, ingress, RBAC) and hands-on experience with AKS or AKS Arc specifically.
Solid grasp of Windows Server clustering technologies — Failover Clustering, Storage Spaces Direct (S2D), Hyper-V — and networking concepts (VLANs, SET switching, RDMA).
Experience with Azure Arc for hybrid resource management, policy enforcement, and monitoring.
Scripting/automation proficiency in PowerShell and/or Azure CLI; exposure to infrastructure-as-code (Bicep, ARM templates, or Terraform).
Familiarity with Microsoft Entra ID (Azure AD), including hybrid identity concepts (Azure AD Connect, conditional access) as applied to Arc-connected resources.
Demonstrated ability to write clear technical documentation — SOPs, runbooks, and PIR/post-mortem reports.
Comfortable working directly with clients to gather requirements and communicate technical tradeoffs.

Other Requirements

Microsoft certifications: AZ-800/AZ-801 (Windows Server Hybrid Administrator), AZ-500 (Security), or AZ-104 (Azure Administrator); CKA/CKAD is a plus.
Experience with GitHub Actions or Azure DevOps pipelines, including OIDC-based authentication to Azure.
Exposure to FlexLM or other license-server management in an HPC/EDA-adjacent environment.
Prior experience supporting regulated or client-facing engagements where documentation rigor (PIR, change control) is contractually required.
Familiarity with GPU/accelerator scheduling on Kubernetes, or with high-performance storage (e.g., FSx for Lustre or equivalent) is a plus, though not core to this role.
