Senior OpenShift Platform Engineer - WebSphere Modernization

Client is undertaking a strategic Modernization 3.0 initiative to migrate legacy WebSphere Application Server workloads onto a modern OpenShift Container Platform. We are seeking a Senior OpenShift Platform Engineer with deep Red Hat platform engineering expertise and a strong DevOps/SRE background to lead containerization and migration efforts in a mission-critical government tax environment. The ideal candidate brings hands-on experience building and operating enterprise-grade OpenShift clusters, automating infrastructure delivery with Terraform and GitOps tooling, and guiding application teams through container-native transformation. This is a high-impact engagement where your platform engineering skills will directly enable them deliver faster, more resilient processing capabilities.

• Lead the design, build, and operationalizing of Red Hat OpenShift clusters to host modernized WebSphere workloads, ensuring high availability, security, and compliance with government standards.
• Drive the containerization and migration of legacy WebSphere Application Server (WAS) applications to OpenShift-native deployments, leveraging tools such as IBM Transformation Advisor where applicable.
• Define and implement GitOps-based deployment pipelines using ArgoCD and GitHub Actions to automate application delivery across Our Client development, staging, and production environments.
• Author and maintain reusable Infrastructure-as-Code (IaC) modules using Terraform and Ansible to provision and manage OpenShift platform components and supporting cloud infrastructure.
• Perform SRE-aligned platform operations including performance tuning, capacity planning, incident response, and software lifecycle management for OpenShift environments.
• Engage Client application and architecture teams to define container migration strategies, establish deployment standards, and support onboarding of WebSphere-based services to the OpenShift platform.
• Implement and manage observability stacks (Prometheus, Grafana, Thanos, Datadog) to provide end-to-end monitoring, alerting, and SLO/SLA visibility across modernized Our Client tax system components.
• Establish and enforce OpenShift platform security posture including RBAC, network policies, image scanning, and secrets management in alignment with Our Client and government compliance requirements.
• Collaborate with IBM delivery leads and Client stakeholders to track modernization progress, manage risks, and communicate platform health and migration milestones.
• Contribute to internal capability building by mentoring junior engineers, documenting platform run books, and sharing Red Hat OpenShift best practices within the Our Client engagement team.

Requirements

• Red Hat OpenShift Container Platform - cluster deployment, configuration, upgrades, and day-2 operations in enterprise environments
• Kubernetes administration with CKA-level proficiency, including workload management, Helm/Kustomize packaging, and namespace governance
• CI/CD pipeline engineering using GitOps patterns with ArgoCD, GitHub Actions, Jenkins, or equivalent tooling
• Infrastructure-as-Code delivery using Terraform and Ansible across cloud or on-premise environments
• Containerization of enterprise Java applications, with an understanding of WebSphere or equivalent application server migration pathways
• Observability and monitoring platform management using Prometheus, Grafana, Thanos, or Datadog in production SRE contexts
• Cloud platform experience across at least one of IBM Cloud, AWS, or Azure including networking, storage, and identity fundamentals
• Stakeholder engagement and technical consulting skills, with experience working in regulated or government sector environments

• Hands-on experience with IBM WebSphere Application Server modernization tools such as IBM Transformation Advisor or WebSphere Liberty migration
• Exposure to IBM Cloud Paks and OpenShift-based middleware deployments in financial services or government contexts
• Experience with Kafka or event-driven architecture patterns supporting microservices decomposition from monolithic Java applications
• Familiarity with Our Client, South African government IT governance frameworks, or equivalent public sector compliance and procurement standards
• Scripting and automation proficiency in Python or Java to support tooling integration and platform customization
• Knowledge of VMware vSphere or on-premise virtualization platforms relevant to hybrid cloud and lift-and-shift migration scenarios
