Kubernetes Engineer

JobDescription KubernetesEngineer Summary Thisrole is ideal for a Kubernetes expert passionate about container platformtransformation, with strong experience in Rancher environments and AKS, and theability to drive large-scale container migration programs while implementingrobust, scalable, and secure cloud-native architectures. Overview We areseeking a highly experienced Kubernetes Engineer with strong expertise inRancher-managed Kubernetes environments and migration to Azure KubernetesService (AKS). The ideal candidate will lead and execute large-scale containerplatform migrations, enabling seamless transition from on-prem/containerplatforms to Azure managed Kubernetes, while ensuring high availability,scalability, and secure CI/CD-driven deployments. Thisrole requires deep hands-on experience with containerization, Kubernetesoperations, ingress/gateway architectures (HAProxy, NGINX), andenterprise-scale lift-and-shift container migration. KeyResponsibilities 1.Kubernetes Platform Migration (Rancher to AKS) • Leadmigration of Kubernetes workloads from Rancher-managed clusters (on-prem orIaaS) to Azure Kubernetes Service (AKS). •Assess existing cluster configurations, namespaces, workloads, anddependencies. •Define and execute migration strategies (lift-and-shift, re-platform, phasedmigration). •Ensure minimal downtime and zero data loss during migration. 2.Container Workload Migration •Migrate containerized applications to AKS at scale. •Refactor container images and manifests where necessary for AKS compatibility. • Optimizeresource allocation, scaling policies, and pod distribution. 3.Kubernetes Architecture & Design •Design production-grade AKS architectures with: ◦ Highavailability (multi-node pools, zones) ◦Auto-scaling (HPA, cluster autoscaler) ◦Secure networking (VNet integration, private clusters) •Implement best practices for multi-tenant and namespace isolation. 4.CI/CD Integration for Kubernetes •Integrate Kubernetes deployments into CI/CD pipelines using: ◦Azure DevOps / GitHub Actions / GitLab CI •Implement GitOps practices (ArgoCD/Flux) where applicable. •Automate build, test, and deployment of containerized applications. 5.Ingress & Gateway Architecture •Design and implement ingress and gateway solutions using: ◦NGINX Ingress Controller ◦HAProxy-based gateways/load balancers •Configure routing, SSL termination, rate limiting, and security policies. •Ensure high availability and fault tolerance of ingress layer. 6.Networking & Security • ConfigureKubernetes networking (CNI, network policies). •Implement secure communication using TLS, secrets, and RBAC. •Integrate with Azure services such as Azure AD, Key Vault, and PrivateEndpoints. 7.Observability & Monitoring •Implement monitoring and logging using: ◦Azure Monitor for Containers ◦Prometheus & Grafana ◦ LogAnalytics •Define SLIs/SLOs and alerting strategies. 8.Performance Optimization •Optimize cluster performance, pod scheduling, and resource utilization. •Conduct load testing and capacity planning for large-scale workloads. 9.Automation & Infrastructure as Code •Provision and manage infrastructure using: ◦Terraform ◦ ARM/ Bicep •Automate cluster setup, upgrades, and scaling. 10.Collaboration & Leadership • Workclosely with DevOps, application, and cloud architecture teams. •Provide guidance on container best practices and Kubernetes usage. •Support enterprise migration programs and troubleshooting. RequiredSkills & Experience Kubernetes& Containerization •Strong hands-on experience with: ◦ Kubernetes (cluster setup, operations,troubleshooting) ◦ Rancher (multi-cluster management) ◦ Docker/container runtime technologies • Deepunderstanding of Kubernetes components (API server, etcd, scheduler, kubelet). AzureKubernetes Service (AKS) •Experience designing and operating AKS clusters. •Knowledge of AKS features such as node pools, scaling, and upgrades. MigrationExpertise •Proven experience in Rancher to AKS migration. •Experience in large-scale container workload migration. •Hands-on experience in lift-and-shift container migrations. Ingress& Gateway Technologies •Strong experience with: ◦ NGINX Ingress Controller ◦ HAProxy load balancing and gatewayconfigurations CI/CD& DevOps •Experience integrating Kubernetes with CI/CD tools: ◦ Azure DevOps, GitLab CI/CD, GitHub Actions •Familiarity with GitOps tools (ArgoCD, Flux). Networking& Security •Understanding of Kubernetes networking (CNI plugins, service mesh optional). •Experience with RBAC, secrets management, and TLS. Scripting& Automation •Proficiency in Bash, Python, or PowerShell. PreferredQualifications •Azure certifications (e.g., Azure Administrator / Azure DevOps Engineer /Kubernetes certifications (CKA/CKAD)). •Experience with service mesh (Istio, Linkerd). •Familiarity with container security tools (Aqua, Twistlock, Trivy). SoftSkills •Strong analytical and troubleshooting abilities. •Excellent communication and collaboration skills. •Ability to work in fast-paced migration programs. Education •Bachelor’s or Master’s degree in Computer Science, Engineering, or relatedfield. ExperienceLevel •6–10+ years of IT experience. • 3–5+years of hands-on Kubernetes experience. •Proven track record in enterprise-scale container migration projects. KeyCompetencies •Kubernetes Platform Engineering •Rancher to AKS Migration •Container Workload Modernization •Ingress & Gateway Architecture (NGINX, HAProxy) •CI/CD & GitOps for Kubernetes
