    • Integrate LDAP authentication with Kubernetes and CI/CD tooling
    • Support identity federation patterns across enterprise platforms
    • Design and maintain high availability and replication strategies
    • Diagnose and resolve directory performance, latency, and synchronisation issues
  • CI/CD Engineering (Jenkins)
    • Develop and maintain Jenkins pipelines using Groovy (pipeline-as-code)
    • Build and manage shared libraries and governance frameworks
    • Integrate Jenkins with Kubernetes-based build agents
    • Implement secure credential and secrets management practices
    • Integrate automated testing into CI/CD workflows
    • Support release orchestration and deployment automation

Supporting Skills

  • Strong Working Knowledge: Docker (multi-stage builds, image optimisation, secure base images), Python (automation, Scripting, infrastructure tooling)
  • Working Knowledge: AWS (IAM, networking concepts, container services), Terraform (infrastructure-as-code principles and module usage), Other networking technologies relevant to secure infrastructure environments

Leadership & Governance Responsibilities

  • Act as a technical point of contact for DevOps-related queries
  • Support technical design authority decisions for incoming work
  • Oversee governance and assurance of production releases
  • Provide mentoring, coaching, and performance feedback to engineers
