Azure Landing Zone engineering - build, enhance, and automate enterprise landing zones

Azure governance & controls - develop Azure Policies, RBAC, blueprints, and compliance guardrails

Infrastructure as Code delivery - author and maintain IaC using Bicep or Terraform

DevOps engineering - implement CI/CD pipelines, Git workflows, and automated deployments

Cloud platform reliability - ensure availability, performance, and operational excellence

Cross‑team collaboration - work with multi‑cloud engineering teams to drive standards and best practices

Azure expertise across policies, governance, networking, compute, identity, and platform services

IaC development using Bicep or Terraform (must be able to write code, not just run templates)

CI/CD pipelines using Azure DevOps or GitHub Actions

Git repositories - strong understanding of branching, PRs, code reviews

DevOps mindset - automation‑first, iterative delivery, shift‑left engineering

Strong scripting or development capability (PowerShell, Python, or similar)

Experience working in distributed teams (UK + offshore)
