Senior Infrastructure Engineer

Across government, modern infrastructure underpins the delivery of secure, resilient and scalable digital services. As organisations transition from legacy estates to cloud-first environments, the need for robust infrastructure capability—combining reliability, automation and security—has never been greater. Ofgem plays a vital role in the UK’s energy system, protecting consumers and enabling a more secure, fair and sustainable energy future, and strong infrastructure services are fundamental to delivering this mission.

Ofgem is on an ambitious transformation journey. Within the Digital, Data and Security Services (DDSS) directorate, we are modernising our core infrastructure, evolving from legacy environments to hybrid and cloud-native platforms. This includes strengthening our Azure capability, improving automation and embedding consistent standards across infrastructure delivery.

As a Senior Infrastructure Engineer, you will play a key role in delivering and maintaining Ofgem’s infrastructure services. You will work across legacy, hybrid and cloud environments, ensuring systems are reliable, secure and aligned with enterprise standards. You will combine hands-on engineering with technical leadership, supporting colleagues, influencing design decisions and driving continuous improvement across the infrastructure estate.

This is a technically focused role within a fast-paced and evolving environment, offering the opportunity to work on both operational services and transformation initiatives.

You will be responsible for:

• Delivering and supporting Azure Legacy, Azure Hybrid and Azure Cloud infrastructure environments, ensuring reliability, performance and security across services.
• Working with architects and delivery teams to translate designs into operational infrastructure solutions aligned with enterprise standards.
• Providing technical leadership and acting as an escalation point for complex infrastructure issues.
• Leading troubleshooting and root cause analysis, implementing long-term solutions to improve system stability and resilience.
• Developing automation and configuration management approaches using tools such as PowerShell, Terraform and Azure CLI.
• Supporting the adoption of modern engineering practices, including Infrastructure as Code, CI/CD and monitoring solutions.
• Managing infrastructure components across their lifecycle, including patching, backup, disaster recovery and compliance activities.
• Collaborating with vendors and third-party providers, ensuring effective delivery of infrastructure services.
• Contributing to continuous improvement initiatives across infrastructure, tooling and operational processes.

We are looking for:

A technically strong infrastructure professional who can operate effectively across both legacy and modern cloud environments. You will bring hands-on experience in Azure and hybrid infrastructure, alongside a proactive approach to problem-solving and service improvement.

You may come from an infrastructure, cloud engineering or DevOps background, but you will demonstrate:

• Strong experience managing Azure and hybrid infrastructure environments
• Experience with automation tools and scripting, such as PowerShell, Terraform or Azure CLI
• A solid understanding of infrastructure security, networking and operational best practice
• Experience troubleshooting complex systems and delivering sustainable improvements
• The ability to collaborate with technical and non-technical stakeholders across teams

A relevant certification such as Microsoft Certified: Azure Administrator Associate is expected.

Experience mentoring colleagues and contributing to capability development would be beneficial.

This is an opportunity to play a key role in modernising Ofgem’s infrastructure landscape. You will help ensure that core systems are resilient, scalable and fit for the future, supporting the organisation’s digital transformation and enabling delivery of critical services.
