The Team

We are a global, independent, multidisciplinary consultancy delivering sustainable engineering and design solutions across the built environment. With over 1,200 engineers and designers across 29 locations, we apply our expertise to local market conditions to deliver resilient, low-carbon engineering solutions. We are 100% partner-owned and are proud to have been named Building Magazine’s Engineering Consultant of the Year in 2024, 2022 and 2021.

As part of this role, you will join our dedicated data centre team. Established in 2006, we have delivered over 2,000 MW of capacity for our clients worldwide. In 2025, we were named Data Centre Consultancy of the Year by Data Centre Review and were ranked in the top 10 by Data Centre Magazine in 2023.

The Role

This is an excellent opportunity for an experienced and client-focused mechanical engineer to join our Critical Systems team and play a leading role in ensuring the successful delivery of innovative mechanical design solutions for some of the most exciting and high-profile projects in the data centre and critical systems fields, both in the UK and internationally.

The role will include leading and supporting mechanical engineers in the delivery of designs, while managing fees, programmes and design quality. You will communicate clearly with project teams, clients and other disciplines, and remain actively involved in the design process, producing deliverables where required.

You will help maintain and build strong client relationships, supporting repeat business through trusted delivery, clear communication and a strong understanding of client needs. You will also contribute to work-winning activity, helping to identify opportunities and support proposals where appropriate.

You will be a Chartered Engineer, educated to degree level in Mechanical Engineering or Building Services Engineering (MEng, BEng or equivalent), with experience in a mechanical engineering role within a data centre, critical systems or building services context.

Given the client-facing nature of this role, you must also have proven experience of client engagement.

You will have experience in the data centre field, including a strong understanding of the principles of data centre design and delivery across a range of projects. In your most recent position, you will have consistently demonstrated your ability to manage multiple large-scale projects and less experienced engineers to deliver to client expectations.
