Job Description:

Azure Landing Zone & Governance

• Design and evolve Azure landing zones aligned with the Microsoft Cloud Adoption Framework and Azure Well-Architected Framework.
• Own subscription, management group, resource group, naming, tagging, RBAC, and governance standards.
• Establish Azure Policy, Defender for Cloud, Sentinel, Log Analytics, and diagnostic standards.
• Review current cloud architecture and produce prioritized remediation plans
• Design highly available, secure, multi-region, and zone-redundant architectures for AI platform.
• Architect and deploy scalable Azure PaaS—including managed kubernetes and databases to meet enterprise performance, data integration and security requirements
• Design and manage enterprise Azure API Management (APIM) instances to securely expose, govern, and scale microservices and PaaS endpoints.

Azure Kubernetes Service (AKS)

• Design and operate production-grade AKS clusters, including node pool strategies, autoscaling, and node image upgrade pipelines.
• Configure AKS networking: Azure CNI or Overlay/Cilium, private cluster endpoints, egress controls via Azure Firewall, and ingress via AGIC or NGINX with WAF.
• Implement AKS security hardening: Entra workload identity federation, Azure RBAC for Kubernetes, admission controllers (Azure Policy / Gatekeeper), and Key Vault secrets injection via CSI driver.
• Establish GitOps-based cluster configuration management using Flux CD or Argo CD; define cluster upgrade and patching cadence.
• Set up AKS observability: Container Insights, Prometheus/Grafana, and distributed tracing via Application Insights or OpenTelemetry.
• Define AKS backup and disaster recovery using Velero, and integrate AKS cost governance into overall cloud cost management practices.

Networking & Connectivity

• Design secure Azure networking: hub-spoke topology, private endpoints, private DNS zones, ingress, and egress controls.
• Define peering, ExpressRoute, and VPN patterns for hybrid and multi-region connectivity.
• Govern DNS resolution for AKS private clusters, including CoreDNS customization and Azure Private DNS integration.
• Implement robust Azure load balancing solutions using Traffic Manager, Application Gateway, and Azure Load Balancer to optimize traffic distribution, performance, and high availability.

Identity, Security & Compliance

• Partner with security and engineering teams to strengthen identity, access, secrets management, monitoring, and compliance controls.
• Design Entra ID integration, RBAC, managed identities, service principals, workload identity federation, and privileged access patterns.
• Co-implement high-priority security, reliability, and governance improvements.

Infrastructure as Code & CI/CD

• Develop and maintain Terraform / OpenTofu IaC modules for AKS clusters, node pools, networking, RBAC, and add-on configuration.
• Establish GitOps workflows for Kubernetes manifests and Helm chart promotion across environments.
• Integrate cluster provisioning and application deployment into GitHub Actions or Azure DevOps pipelines.

Reliability, DR & Operations

• Define backup, disaster recovery, RTO/RPO, and restore validation practices for AKS and supporting infrastructure.
• Establish and validate enterprise-grade backup, disaster recovery, and data retention policies to guarantee business continuity and strict RPO/RTO compliance.
• Implement chaos engineering and failure injection practices to validate cluster resilience.
• Build documentation, architecture diagrams, runbooks, and operational standards.
• Mentor DevOps, platform, and engineering teams on Azure and AKS best practices.

In the first engagement phase, this person will:

• Review the current Azure environment, AKS footprint, and deployment approach.
• Identify security, reliability, governance, and operational gaps — including AKS cluster configuration, node security, and workload identity posture.
• Design a target-state Azure landing zone with AKS as a first-class platform component.
• Establish IaC standards for AKS cluster lifecycle, node pool management, and add-on configuration.
• Implement or guide deployment of foundational AKS and Azure networking infrastructure.
• Create documentation and knowledge-transfer materials for internal teams.

• 8+ years of experience in cloud infrastructure, platform engineering, DevOps, or security architecture.
• 5+ years of hands-on Microsoft Azure experience.
• 3+ years of production AKS experience — cluster networking, security, GitOps, and workload operations.
• Strong experience designing Azure landing zones or enterprise Azure environments.
• Hands-on experience with Terraform, OpenTofu, Bicep, or similar IaC tooling.
• Strong knowledge of Azure networking, private connectivity, DNS, routing, and ingress patterns.
• Experience with Entra workload identity, managed identities, Azure RBAC for Kubernetes, and admission control.
• Experience with Azure Policy, Defender for Cloud (including Defender for Containers), Sentinel, and Log Analytics.
• Experience designing backup, restore, resiliency, and disaster recovery practices.
• Ability to create clear technical documentation, diagrams, standards, and runbooks.
• Strong communication skills across engineering, security, and leadership teams.

• Azure Solutions Architect Expert certification.
• Azure Security Engineer or Cybersecurity Architect certification.
• Certified Kubernetes Administrator (CKA) or equivalent hands-on AKS experience.
• Terraform Associate or equivalent IaC experience.
• Experience with GitHub Enterprise, GitHub Actions, or Azure DevOps for CI/CD pipelines.
• Experience in regulated, SaaS, multi-tenant, or enterprise production environments.
• Familiarity with CIS Azure Benchmarks, CIS Kubernetes Benchmark, Microsoft Cloud Security Benchmark, and Zero Trust principles.
• Experience mentoring platform or DevOps engineers on Azure and Kubernetes best practices.
