About The Role

We are looking to strengthen our engineering team with a Product Design Manger 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 the operational, commercial, and environmental objectives of the wider project.

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

  • Driving digital design excellence, supporting the use of BIM and 3D modelling to improve coordination, data integration, and project outcomes.

  • Challenging and improving technical standards, encouraging innovation and the use of repeatable, low-carbon, and cost-effective solutions.

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

  • Building strong working relationships with internal and external stakeholders, ensuring that designs reflect the needs of operators, contractors, regulators, and the community.

  • Championing best practice across quality, health and safety, and performance – both within your own team and the wider Alliance.

  • Mentoring junior engineers and designers, creating a positive learning culture and helping others grow their skills and confidence.

  • Driving collaboration across disciplines, promoting a one-team mindset and helping to unlock value at every stage of the design process.

About You

  • A degree, HNC or HND in civil engineering or a related discipline.

  • Proven experience in a design or engineering leadership role within complex infrastructure or water-related projects.

  • A working knowledge of CDM 2015 regulations, with prior experience acting as Principal Designer or managing design risk.

  • A strong understanding of project delivery in a multi-disciplinary environment, ideally within an alliance or joint venture.

  • Experience with digital design tools, BIM workflows, and integrated design processes.

  • Excellent communication and stakeholder engagement skills – able to influence, lead, and work collaboratively at all levels.

  • A proactive, solution-focused mindset with a commitment to quality and continuous improvement.
