FULL DESCRIPTION

Platform Engineer

Join our Engineering Acceleration Team within the Technology & Innovation Group and play a critical role in enhancing our cloud-native infrastructure and developer platform capability. We are looking for a Platform Engineer to join the team to empower software and engineering teams to deliver high-performance, scalable, and secure systems by improving the way we build, deploy, and run applications across Kubernetes and hybrid cloud environments.

Responsibilities:

  • Deploy and operate Kubernetes clusters (AKS/EKS/on-prem) across hybrid-cloud and virtualised environments.
  • Define and implement best practices around scaling, security, high availability, and tenancy.
  • Enable application delivery through GitOps workflows and Helm-based deployments.

Cloud Infrastructure & Automation

  • Use Terraform and Helm to automate provisioning and configuration of infrastructure.
  • Build reusable modules and automation for developer and infrastructure teams.
  • Contribute to shared pipelines, templates, and documentation to enable self-service.
  • Develop and maintain Cloud Operators for managing application lifecycles and platform services.
  • Support secure and compliant provisioning of services and resources across multiple environments.

CI/CD and Software Delivery Enablement

  • Extend and manage CI/CD pipelines using Bitbucket Pipeline or Azure DevOps.
  • Support build, packaging, deployment, and lifecycle management processes.
  • Help teams adopt modern delivery practices through tooling and coaching.
  • Join wider Application Development squads to accelerate delivery of key projects.

Observability, Site Reliability

  • Operate production workloads with an SRE mindset: measure reliability, define SLOs, and reduce toil through automation.
  • Contribute to on-call readiness, incident response processes, and root cause analysis. As well as being available for escalated out of hours calls where needed.
  • Define and improve availability, performance, and scalability through platform-level metrics and service reviews.
  • Apply security best practices for Kubernetes (RBAC, network policies, secrets).
  • Work with internal teams to ensure audit, compliance, and cost controls are met.
  • Support secure identity, access, and secrets management integrations.

Skills and experience required:

  • Degree in Computer Science, Systems Engineering, or a related field.
  • Collaborative and adaptable with a platform mindset.
  • Strong interest in enabling engineering teams through infrastructure and automation.
  • Confident communicator who can explain infrastructure decisions to developers and non-specialists.
  • Ability to work well across teams and disciplines, especially in high-performance environments.
  • Self-motivated and pragmatic with a continuous improvement approach.

Experience with:

  • Kubernetes provisioning and lifecycle management (AKS, EKS, on-prem)
  • Infrastructure as Code (Terraform, Helm)
  • Containerisation and orchestration (Docker, Helm, Operators)
  • Cloud platforms (Azure, AWS)
  • CI/CD pipelines (Azure DevOps, Bitbucket Pipelines, GitHub Actions)
  • GitOps (e.g., ArgoCD, FluxCD)
  • Monitoring, logging, and alerting (Prometheus, Grafana, Loki)
  • Scripting and automation (Python, Bash, etc.)
