Job Description :

Senior OpenShift Administrator with deep expertise in Red Hat OpenShift Container Platform (OCP) and AWS-based clusters. This role will be responsible for the administration, configuration, scaling, and troubleshooting of OpenShift clusters supporting enterprise-grade applications within a cloud-native environment. The ideal candidate has a strong Linux and Red Hat background, container orchestration experience, and a solid understanding of AWS infrastructure services and networking.

Key Responsibilities

  • Design and implement cluster management strategies-worker node scaling, load balancing, auto-scaling groups, and multi-AZ architectures.
  • Manage cluster resources, namespaces, and policies for security, compliance, and governance.
  • Deploy and troubleshoot applications and operators using Helm, YAML manifests, and CI / CD pipelines.
  • Collaborate with DevOps and Cloud Engineering teams to optimize Kubernetes and OpenShift deployments for performance and cost efficiency.
  • Integrate OpenShift with AWS services (EBS, Route53, ALB / NLB, IAM, CloudWatch, etc.).
  • Automate operational tasks using Ansible, Terraform, or other infrastructure-as-code (IaC) tools.
  • Monitor and optimize cluster health, logging, and alerting through Prometheus, Grafana, and Elasticsearch stacks.
  • Ensure platform security, including RBAC configuration, certificate management, and vulnerability patching.
  • Participate in incident response and root cause analysis for cluster or containerized workloads.
  • Document procedures, SOPs, and architecture diagrams to support ongoing operations.

Required Skills & Experience

  • 8+ years of overall IT systems administration experience.
  • 3+ years dedicated to Red Hat OpenShift (v4.x preferred).
  • Strong background in Linux administration (Red Hat Enterprise Linux or CentOS).
  • Proven hands-on experience managing OpenShift clusters in AWS (EKS, EC2, S3, IAM integration).
  • Proficiency with Kubernetes concepts-pods, services, deployments, ingress, config maps, secrets, and persistent volumes.
  • Experience with CI / CD tools such as Jenkins, GitLab CI, or ArgoCD.
  • Strong scripting and automation skills (Bash, Python, Ansible, or Terraform).
  • Familiarity with networking and security concepts within AWS and OpenShift (VPC, subnets, routing, TLS, RBAC).
  • Excellent troubleshooting and performance optimization skills.
