Our mission
Our mission is to deliver clean, affordable energy for all. Our Small Modular Reactor (SMR) provides a British solution to a global energy challenge. We are in pole position to become a global leader in SMRs and the UK’s premier green export technology.
The team
The Layout & Installation Assemblies team plays a central role in turning engineered concepts into deployable reality. Focused on modularisation, constructability and integration, the team ensures that complex systems are translated into efficient, buildable assemblies that support safe, repeatable and scalable deployment.
The role
In this context, we are looking for a Layout and Installation Assemblies Engineer - Site Specific, reporting to the Manager - Site Specific Layout. Operating within a focused Layout and Installations team, you will take ownership of a defined area within a site-specific Reactor Island Layout, driving integration of Structures, Systems and Components in order to meet the applicable Safety, Cost and Schedule targets.
This is a hands-on engineering role at the heart of our modular build philosophy. You will develop site-specific layouts for mechanical, electrical and plumbing (MEP) systems, define how modules are manufactured, installed and commissioned, and ensure designs are aligned to safety, quality and programme objectives. Working across disciplines, you will play a key role in delivering a robust, buildable and optimised plant design. You will play a role in interfacing with the customer and the site-specific project teams in order to translate the RR SMR generic design into a site-specific application.
