We are Rolls‑Royce SMR and we’re doing something that’s never been done before. We’re revolutionising an industry. That’s a once‑in‑a‑career opportunity for those excited by such a challenge. This is more than just a job; this is a legacy.
The Layout and Installation Assemblies team is responsible for the design and delivery of Mechanical, Electrical and Plumbing (MEP) modules and installation assemblies across the Reactor Island. These solutions are fundamental to our modular delivery strategy and play a critical role in ensuring safe, efficient and constructible plant design.
As a Senior Engineer - Layout and Installation Assemblies, you will be responsible for the design and delivery of Mechanical, Electrical and Plumbing (MEP) modules and installation assemblies within the Reactor Island Layout design.
You will develop an understanding of the full technical requirements and lifecycle of the modules, creating arrangements and layouts while helping determine manufacturing, installation and commissioning strategies. The role requires a strong understanding of how fluid and waste management systems interface with plant structures, equipment, supporting systems and operational activities across the facility lifecycle.
You will ensure that plant and system arrangements support safe, efficient and practical operation, inspection, testing, maintenance, replacement and eventual decommissioning. Working within a core Layout and Installation Assemblies team, you will have responsibility for the development of a defined cluster of modules within a critical area of the Reactor Island design.
Getting the layout, modularisation and installation design right is absolutely critical to achieving the overall business objective and is a key part of our innovative SMR approach.
