About the Role Client is undertaking a strategic Modernisation 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.   Key Responsibilities Lead the design, build, and operationalisation of Red Hat OpenShift clusters to host modernised 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 modernised 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 company delivery leads and Client stakeholders to track modernisation progress, manage risks, and communicate platform health and migration milestones.
