Senior DevOps Engineer – Kubernetes

Key Responsibilities • Deploy, configure, maintain, and troubleshoot Kubernetes clusters across enterprise and on-premise infrastructure environments. • Perform hands-on Kubernetes cluster installations, including configuring control-plane nodes, worker nodes, cluster networking, and essential infrastructure components. • Support Kubernetes deployments, migrations, upgrades, reconfigurations, and production infrastructure changes. • Troubleshoot Kubernetes cluster issues involving nodes, pods, services, networking, storage, and application availability. • Work directly at client data centers across the UAE to perform infrastructure deployment, configuration, maintenance, and troubleshooting activities. • Support on-premise Kubernetes environments, including bare-metal servers, virtual machines, and private data-center infrastructure. • Diagnose and resolve Kubernetes-related issues using kubectl, Linux command-line tools, logs, and monitoring platforms. • Support Kubernetes cluster provisioning using kubeadm, RKE2, K3s, Rancher, OpenShift, or equivalent Kubernetes deployment technologies, depending on the client environment. • Troubleshoot Kubernetes control-plane and worker-node issues, including cluster connectivity, service availability, scheduling, and resource utilization. • Support Linux server administration, including configuration, patching, troubleshooting, system performance monitoring, and operational maintenance. • Diagnose infrastructure and networking issues involving DNS, NTP, firewall rules, routing, ports, load balancing, and connectivity. • Write, maintain, and troubleshoot Bash/Shell scripts for infrastructure automation, deployment activities, and operational tasks. • Support containerized application deployments using Docker, Kubernetes, Helm, and container registries. • Assist with Kubernetes certificate management, TLS/SSL configuration, and secure cluster connectivity. • Support database infrastructure and containerized services, including PostgreSQL, where applicable. • Monitor Kubernetes clusters and infrastructure using Prometheus, Grafana, ELK, Loki, or equivalent observability tools. • Investigate production incidents, identify root causes, implement fixes, and recommend preventive actions. • Perform infrastructure deployment validation, testing, and troubleshooting before production go-live. • Work with internal engineering teams and customer infrastructure teams to coordinate deployments, migrations, maintenance, and incident resolution. • Support Kubernetes infrastructure within restricted-access or security-sensitive client environments, where applicable. • Communicate deployment progress, technical issues, troubleshooting findings, and remediation plans clearly to client stakeholders. • Prepare and maintain technical documentation, deployment procedures, troubleshooting guides, operational runbooks, and incident reports. • Ensure infrastructure deployments and operational changes follow established security, reliability, and production standards. • Travel to customer data centers and client locations across the UAE as required. Required Experience • Approximately 4–5 years of relevant experience across DevOps, Site Reliability Engineering, Kubernetes, Linux infrastructure, or platform engineering. • Proven hands-on experience deploying and configuring Kubernetes clusters, rather than solely managing application deployments within existing clusters. • Practical understanding of Kubernetes architecture, including control-plane components, worker nodes, pods, services, networking, scheduling, and storage. • Experience performing Kubernetes cluster installation, configuration, maintenance, troubleshooting, or upgrades. • Hands-on exposure to on-premise Kubernetes or self-managed Kubernetes infrastructure, preferably within physical or private data-center environments. • Experience with Kubernetes deployment and management tools such as kubeadm, RKE2, K3s, Rancher, OpenShift, or equivalent technologies. • Strong Linux administration and troubleshooting skills, including experience working extensively through the Linux command line. • Working knowledge of Bash/Shell scripting for infrastructure administration, troubleshooting, and automation. • Understanding of containerization technologies, particularly Docker and Kubernetes. • Practical knowledge of Linux networking, including DNS, firewalls, routing, ports, network connectivity, and load balancing. • Experience troubleshooting Kubernetes infrastructure and production issues involving cluster health, node availability, networking, resource utilization, and application connectivity. • Familiarity with Kubernetes deployment tools such as kubectl, Helm, and container registries. • Experience with production monitoring, logging, and observability tools such as Prometheus, Grafana, ELK, Loki, or equivalent platforms. • Ability to investigate technical issues, analyze logs, identify root causes, and implement corrective actions. • Experience supporting production environments and performing infrastructure changes, deployments, or migrations. • Ability to work independently and take ownership of hands-on infrastructure deployment and troubleshooting tasks. • Strong technical communication skills and ability to coordinate directly with client infrastructure, security, and engineering teams. • Comfortable working fully onsite within the UAE, including customer data centers and other client locations. • Willingness to work within security-sensitive or restricted-access environments where required. Preferred Experience • Experience deploying and operating highly available on-premise Kubernetes clusters, including multi-control-plane and multi-worker-node environments. • Hands-on experience with kubeadm-based Kubernetes cluster bootstrapping. • Understanding of etcd, including cluster health, quorum, peer membership, backup, recovery, and troubleshooting. • Experience with Kubernetes certificates, PKI, SAN configuration, certificate renewal, and CA rotation. • Previous experience deploying Kubernetes within air-gapped, offline, restricted-access, or high-security data-center environments. • Experience supporting infrastructure migrations from cloud environments to on-premise or self-managed Kubernetes. • Knowledge of PostgreSQL administration, primary/replica replication, high availability, and database troubleshooting. • Experience managing private container registries, including Docker Distribution, Harbor, JFrog Artifactory, Nexus, or equivalent technologies. • Exposure to distributed storage technologies such as Ceph, MinIO, SeaweedFS, or equivalent platforms. • Experience with infrastructure automation tools such as Terraform, Ansible, Python, or similar technologies. • Familiarity with Kubernetes networking technologies such as CNI plugins, Ingress Controllers, HAProxy, MetalLB, NGINX, or equivalent s
