About the role

We are looking for a Project Integration Manager to support a major first-of-a-kind UK Small Modular Reactor programme, in the Nuclear sector. Working within an integrated client environment, you will help coordinate delivery across functions, contracts and workstreams, bringing structure and momentum to cross-boundary matters.

Supporting the Project Integration Lead and Senior Project Integration Manager, you will manage assigned integration workstreams and turn interfaces, dependencies, assumptions, actions and decisions into clear, tracked priorities. You will bring stakeholders together, maintain visibility of integration matters and support timely escalation when issues require senior attention.

Key responsibilities

• Support the operation and continuous improvement of the project integration capability.

• Manage assigned integration workstreams, interfaces and dependencies across internal teams, enabling functions, Tier 1 contractors and strategic workstreams.

• Identify and progress cross-boundary interfaces, dependencies, assumptions, actions and decisions, ensuring ownership is clear and progress is tracked.

• Coordinate the closure of cross-cutting actions and decisions, confirming accountabilities and escalating blockers where required.

• Maintain clear records of integration issues, risks, opportunities, dependencies, assumptions, actions and decision points.

• Prepare concise integration updates for reporting, governance forums and senior decision-making.

• Support the development and consistent use of integration tools, registers, reporting processes, ways of working and escalation routes.

• Work with Project Controls so that integration inputs, dependencies, assumptions and interface matters are visible in schedules, contractor programme reviews and the Integrated Master Schedule.

• Support gateway reviews, assurance activity and action close-out by coordinating inputs and maintaining visibility of progress.

• Help clarify the scope, ownership, milestones, dependencies, assumptions and decisions required for strategic and enabling workstreams.

• Coordinate stakeholder engagement across project management, risk, commercial, procurement, design management, systems engineering, technical assurance, communications and supplier teams.

• Provide task direction and support to Integration Analysts or Coordinators on assigned activities.

• Promote consistent cross-functional ways of working, lessons learned and continuous improvement.
