Job description

Are you a technically strong Infrastructure Engineer ready to take the next step into IT management? Or perhaps you're already managing infrastructure and looking for greater ownership, autonomy and influence?

We're working with an established, multi-site UK business to recruit a Senior Infrastructure Engineer / Infrastructure Manager to take ownership of its IT infrastructure, manage key technology suppliers and support an exciting programme of business transformation.

This is an excellent opportunity for someone who enjoys combining hands‑on technical expertise with operational management, stakeholder engagement and project delivery.

The Opportunity

Reporting into the senior IT leadership team, you'll take responsibility for the day-to-day management and continual improvement of a fully cloud‑based Microsoft environment. You'll oversee external technology partners, ensuring infrastructure services, end‑user support and device management operate effectively across a geographically dispersed business. Beyond BAU, you'll contribute to projects spanning AI, automation, cybersecurity, systems integration and new office infrastructure.

What You'll Be Doing

• Managing and improving Microsoft Azure, Microsoft 365 and Intune environments.
• Overseeing third‑party IT suppliers, service delivery, escalations and performance.
• Taking ownership of infrastructure operations, device lifecycle management, licensing and procurement.
• Supporting networking infrastructure, including Meraki, and regional office setups and relocations.
• Working closely with senior stakeholders, translating technical challenges into practical business solutions.
• Contributing to technology projects involving AI, automation, cybersecurity and digital transformation.
• Identifying opportunities to improve IT services, processes and operational efficiency.

What We're Looking For

• Strong technical background in IT infrastructure, ideally progressing through 2nd/3rd line support into senior engineering or management.
• Hands‑on experience with Microsoft Azure, Microsoft 365 and Intune.
• Good networking knowledge, ideally including Cisco Meraki.
• Experience managing external IT suppliers, service providers and escalations.
• Confidence engaging with senior stakeholders and communicating technical concepts clearly.
• A proactive, commercially aware approach with the ability to work autonomously and take ownership.
• An interest in developing broader management and strategic IT responsibilities.

Why Consider This Role

This isn't simply another infrastructure support position. You'll have genuine ownership of a significant part of the IT operation, the freedom to make improvements and the opportunity to work alongside an experienced IT leader who encourages autonomy and professional development. For an ambitious Senior Engineer, there's an opportunity to develop towards infrastructure management and potentially broader IT leadership responsibilities as the business evolves.
