Job description

This is a hands-on senior engineering position with plenty of scope to influence technical direction, improve engineering standards and help shape the way cloud infrastructure is designed and delivered. You'll work closely with development, infrastructure and security teams, acting as a technical escalation point and helping drive best practice across the wider engineering function.

What You'll Be Doing

• Design, build and maintain scalable Azure infrastructure using Terraform and Infrastructure as Code.
• Develop and manage production Kubernetes/AKS environments, including upgrades, security, networking and optimisation.
• Establish and improve GitOps and CI/CD practices, using tools such as GitHub Actions, Azure DevOps and ArgoCD.
• Build reusable Terraform modules, deployment templates and automation to improve consistency across environments.
• Design and maintain Azure networking, including VNets, hub-and-spoke architectures, DNS, NSGs and firewall solutions.
• Implement cloud security practices across identity, access management, container security and infrastructure.
• Develop and maintain Helm charts and standardised deployment processes for application teams.

• Strong production experience with Kubernetes, ideally AKS.
• Good understanding of Azure networking and cloud architecture.
• Experience building and maintaining CI/CD pipelines.
• Experience with GitOps, ideally using ArgoCD or a similar platform.
• Strong knowledge of Docker and containerised environments.
• Experience with Helm and Kubernetes application deployment.
• Good understanding of cloud security, IAM, RBAC and secure CI/CD practices.
• Strong Linux administration and troubleshooting skills.
• Proficiency with Python, Bash or similar scripting languages.
• Experience contributing to technical architecture, design documentation and engineering standards.
• Comfortable communicating technical concepts to both technical and non-technical stakeholders.
• Experience mentoring engineers or acting as a senior technical point of contact.
• Istio or Cilium
• KEDA or Karpenter
• Falco or Kyverno
• Entra ID and PIM
• Observability platforms such as Grafana, Loki or OpenTelemetry
• Experience working within regulated or compliance-focused environments
