Job description

We are looking to strengthen our engineering team with a Project Design Manager at our @One Alliance, Peterborough office, with hybrid working available.

As a Project Design Manager, you’ll take technical ownership of major infrastructure projects from initial feasibility through to detailed design and handover. You’ll coordinate design delivery across multi-disciplinary teams, ensuring designs are practical, sustainable, and aligned with cost, time, and quality expectations.

You’ll act as a key point of contact across the project lifecycle, working closely with project leaders, engineers, construction teams, and external stakeholders to ensure seamless delivery. It’s a hands-on, highly collaborative role that puts you at the centre of some of the most important infrastructure work happening in the region.

Your key responsibilities will include:

• Leading the design process on major capital projects, from early concept through to detailed technical development and design assurance.

• Ensuring design outputs are fully integrated, meeting operational, commercial, and environmental objectives of the wider project.

• Acting as Principal Designer under CDM regulations, managing design risk and ensuring safety considerations at every stage.

• Driving digital design excellence, supporting BIM and 3D modelling to enhance coordination, data integration, and project outcomes.

• Challenging and improving technical standards, encouraging innovation, low-carbon solutions, and cost-effectiveness.

• Liaising with project leaders and delivery teams to plan and allocate design resources effectively, keeping all technical aspects on track.

• Building strong relationships with internal and external stakeholders to ensure designs meet operator, contractor, regulator, and community needs.

• Championing best practices in quality, health and safety, and performance within your team and the wider Alliance.

• Mentoring junior engineers and designers, fostering a positive learning environment and skill development.

• Promoting cross-disciplinary collaboration to maximize value at each design stage.
