Infrastructure Operations Specialist
Azure & Microsoft 365
Help shape reliable, secure and continually improving cloud services at the heart of a major engineering and construction business.
Laing O'Rourke's IT function has renewed its strategy to support the company's ambition to transform the construction industry, making it more sustainable, more productive, and fit for the future.
Technology has a critical role to play in achieving this ambition. Our focus is on applying digital capability in ways that genuinely matter, shaping how complex projects are delivered, how decisions are made, and how innovation improves outcomes for people, communities, and the environment.
Our mission is clear: to create a modern and resilient technology environment where trusted data informs every decision, AI enhances every process, and digital capability enables the organisation to operate with greater scale and productivity.
To deliver this, we are building a different kind of IT function, one that is trusted by the business, forward looking in its thinking, and deeply connected to operational outcomes. We are looking for individuals who are curious, thoughtful, and motivated by contributing to work that has real industry impact.
The role
As an Infrastructure Operations Specialist, you will provide second- and third-line operational support across our cloud environment. Your primary focus will be Microsoft Azure, complemented by support for Microsoft 365 services.
You will help maintain the availability, security, performance and capacity of our services while resolving complex incidents, delivering controlled changes and identifying opportunities to automate and improve how the environment is supported.
Working collaboratively with colleagues across Operations, Engineering, Security, Service Management and the Service Desk, you will provide practical technical guidance and contribute to infrastructure projects, migrations and service improvements.
Key responsibilities
- Operate, monitor and continually improve Microsoft Azure and Microsoft 365 services.
- Provide second- and third-line support, taking complex incidents and problems through investigation, resolution and root cause analysis.
- Administer Azure infrastructure and platform services, including virtual machines, storage, networking, load balancing and private endpoints.
- Support Azure networking and connectivity across VNets, subnets, routing, DNS, Network Security Groups, Azure Firewall and hybrid environments.
- Manage identity and access services using Active Directory and Microsoft Entra ID, including RBAC, privileged access, managed identities, application registrations, enterprise applications and single sign-on.
- Monitor availability, performance and capacity using Azure Monitor, Log Analytics, alerts, dashboards and Service Health.
- Maintain cloud security controls through Microsoft Defender for Cloud, Azure Policy, secure configuration standards and vulnerability-remediation plans.
- Support backup, recovery, resilience and disaster-recovery arrangements, including restoration and continuity testing.
- Monitor Azure consumption and cost, investigate unusual activity and recommend practical configuration, reservation or licensing improvements.
- Automate repeatable activities using PowerShell, Azure CLI and infrastructure-as-code tools such as Bicep or ARM templates.
- Support Exchange Online, Microsoft Teams, SharePoint Online, OneDrive and Intune, including tenant configuration, access, licensing, provisioning, mail flow and endpoint management.
- Contribute to Microsoft 365 governance, data retention, data loss prevention, information protection and eDiscovery controls.
- Plan, document, test and deliver changes with careful consideration of customer impact and operational risk.
- Maintain clear procedures, configuration records, support runbooks and knowledge articles.

- Scripting or automation experience using PowerShell, Azure CLI or comparable tools.
- Familiarity with ITIL-aligned service-management and change-control processes.
- A bachelor's degree in Computer Science, Information Systems or a related subject, or equivalent practical experience.
- A collaborative and customer-focused approach, with the ability to explain technical issues clearly and consider their wider business impact.
Desirable requirements
- Experience with one or more of the following would be beneficial:
- Infrastructure as code using Bicep or ARM templates.
- Windows Server and Linux workloads hosted in Azure.
