About our Team 

At AECOM, our Nuclear Team provide multi-disciplinary consultancy to the nuclear industry in both the nuclear new build and decommissioning sectors. In the new build sector, we are providing engineering support to the developers of the UK’s fleet of new nuclear power stations.

The Nuclear Team are currently engaged on a highly complex nationally significant project for a MoD client. AECOM have been engaged from RIBA 1 through to the current RIBA 3 phase.  The project requires AECOM to provide multidisciplinary design and engineering expertise to collaboratively deliver the project. On this project, the mechanical team are working closely working with the overall project process team and other engineering disciplines, to deliver the required mechanical handling diagrams and mechanical flow diagrams. These diagrams are being produced from models and design calculations and are assisting the overall project to outline the facilities main throughput requirements.

With an interesting and expanding pipeline of both international and UK based projects, as a Graduate Mechanical Building Services Engineer, you will be required to both manage and report on your packages of work with support from Senior Mechanical Engineers in the team, who will support in your continued development.
