Senior Infrastructure Engineer - Azure

Job Title: Senior Cloud Engineer - Azure
Location: London (hybrid, regular office attendance)
Salary: Competitive

Why Apply?
Join a global professional services organisation as its Senior Cloud Engineer, the technical owner of a global Microsoft Azure platform and the Cloudflare edge in front of it.

This is a hands-on senior role: building new services in code, setting the engineering standards others work to, and making a UK-hosted platform genuinely global. You'll shape the platform behind new AI, data and member-facing services, work alongside a managed-service provider that runs the day-to-day estate, and help move everything towards fully automated, Terraform-defined infrastructure.

Key Responsibilities

• Design and engineer new services on Azure (landing zones, governance and policy, containers and AKS, and platform services), delivered as code in Terraform using AI-assisted engineering.
• Take existing infrastructure into code, building automated, repeatable environments through CI/CD pipelines.
• Own Azure networking and connectivity: hub-and-spoke, private endpoints and DNS, firewalling, segmentation and hybrid connectivity.
• Grow the Cloudflare edge from global DNS into WAF, Tunnel, Zero Trust access, Workers and AI Gateway.
• Provide secure hosting and environments for agentic AI platforms, member portals, Microsoft Fabric, Azure SQL and ring-fenced AI environments.
• Design backup and disaster recovery, and run regular, evidenced failover tests with the managed-service provider.
• Keep the platform secure and cost-effective: patching, vulnerability management, Defender for Cloud, hardened configuration and right-sizing.
• Set the technical standards the managed-service provider works to, and review its changes and Terraform against them.
• Advise on new cloud technologies and take part in change management.

Key Requirements

• Substantial production experience engineering Microsoft Azure: compute (including VMs and AKS), networking, storage, platform services and governance.
• Strong knowledge of Azure landing zones and the Cloud Adoption Framework, with the judgement to set standards.
• Hands-on Terraform, written from scratch and delivered through CI/CD pipelines, plus strong PowerShell.
• Deep Azure networking skills, plus experience with public DNS and edge security (ideally Cloudflare, or the appetite to learn).
• Backup and DR design and testing (e.g. Azure Backup, Azure Site Recovery), and patch and vulnerability management.
• A solid grasp of cloud security and Azure identity: Defender for Cloud, Entra ID, managed identities, RBAC and privileged access.
• Strong problem-solving, communication and stakeholder management skills.

Desirable

• Experience supporting Azure data services (Microsoft Fabric, Azure SQL, Synapse).
• Using AI coding assistants for Terraform and automation.
• Experience working with managed-service providers and suppliers.
• Familiarity with SharePoint and Power Platform administration.
• Certifications such as AZ-104, AZ-305, AZ-700, AZ-500 or HashiCorp Terraform Associate.

What's in it for me?

• Competitve Salary.
• Hybrid working in a global organisation operating in 120 countries.
• Genuine technical ownership of a global Azure and Cloudflare platform.
• Greenfield work in container strategy, global scaling, DR, Cloudflare Zero Trust and AI hosting.
• Real influence over engineering standards and cloud strategy.
• Professional development, certification and training support.
