- Nuclear’s first step was to start the technology selection process for Small Modular Reactors (SMRs) in 2023. SMRs can potentially be quicker to deploy and less expensive to build than traditional nuclear power plants because they are smaller, have factory based modular manufacturing and more flexible deployment options. In June 2025, Great British Energy
- Nuclear announced that Rolls-Royce SMR had been selected as the preferred bidder to build the UK’s first SMRs, following a technology selection process that began in 2023.

The Project Integration Manager will support the Project Integration Lead in operating the Project Integration capability for the Gwyndod Project, helping the project to coordinate delivery activity across functions, contracts and work streams.

The role is responsible for managing defined integration work streams and turning cross-boundary interfaces, dependencies, assumptions, actions and decisions into clear, tracked and actively progressed priorities.

Working across internal teams, enabling functions, Tier 1 contractors and strategic work streams, the Project Integration Manager will coordinate stakeholders, maintain visibility of integration matters and support timely escalation where issues require senior attention.

The Project Integration Manager will typically be responsible for integration work streams or cross-functional matters that are less high profile or significant than those led by the Senior Project Integration Manager, while still requiring strong delivery focus, stakeholder coordination and attention to dependency, action and decision management.

This role will work closely with the Project Integration Lead, Senior Project Integration Manager and wider project teams to embed consistent integration ways of working, support project governance and help ensure cross-cutting matters are progressed to resolution.

You will be joining a major first-of-a-kind UK SMR Project at a formative stage. This is a fast-paced role requiring strong delivery capability, confidence…
