Senior Project Manager – Connect Plus Services | M25 Network (Leatherhead / South Mimms / Dartford)

About the Role

At Connect Plus Services, we keep one of the UK’s busiest and most critical road networks moving. As the operational partner responsible for maintaining and improving the M25 and its associated infrastructure, our work impacts millions of journeys every day. From complex structures and major renewals to innovative asset management, our teams deliver projects that keep the network safe, reliable, and ready for the future.

We are now looking for a Senior Project Manager to join our Asset Delivery team, leading the successful delivery of complex highways and structures schemes across the M25 network.

In this role, you will take ownership of projects throughout their full lifecycle, overseeing schemes ranging from £20k to £4m+. Working closely with the Portfolio Manager and wider delivery teams, you will ensure projects are delivered safely, on time, and within budget, while maintaining the highest standards of quality and compliance. You will also provide leadership to Project Managers, Assistant Project Managers and early‑career colleagues, helping to develop capability across the team and drive performance.

The role requires close collaboration with internal teams, supply chain partners and key external stakeholders, including Connect Plus, National Highways and local authorities. You will oversee programme planning and cost forecasting across your portfolio, manage project risks and changes, and chair regular project reviews to ensure performance remains on track. When required, you will also support the Portfolio Manager by stepping into their responsibilities to ensure continuity across the wider programme of works.

What You’ll Be Doing

• Leading the successful delivery of a portfolio of highways and structures projects across the M25 network, ensuring schemes are delivered safely, efficiently and in line with programme and budget expectations.
• Building strong collaborative relationships with the Portfolio Manager and key stakeholders, providing clear reporting on project performance and driving solutions when challenges arise.
• Overseeing portfolio‑level programme management and financial forecasting, reviewing inputs from Project Managers and ensuring the accuracy of cost and income profiles.
• Chairing regular project reviews to ensure risks, priorities and programme milestones remain current and actively managed.
• Managing project change control processes, reviewing compliance with the DBFO contract, and ensuring that risks, issues and dependencies are identified early and addressed effectively.
• Liaising with clients and stakeholders at both project and portfolio level to maintain alignment on delivery objectives.
• Allocating projects to the project management team based on capability, experience and workload, while supporting the development and performance of team members.

Who We’re Looking For

We are seeking an experienced project leader with a strong background in delivering highways construction or maintenance projects, or someone with comparable transferable infrastructure experience. Ideally, you will hold a recognised project management qualification such as PRINCE2 or APM, and a qualification in civil engineering or a related construction discipline would be an advantage.

You should have a solid understanding of CDM regulations, health and safety legislation and environmental considerations associated with highway works. Experience coordinating design teams and managing multiple project interfaces will also be important.

Strong leadership, communication and stakeholder‑management skills are essential, along with the ability to manage budgets, drive performance and build trusted relationships with internal and external partners. You will be proactive in solving problems, confident in presenting information and influencing decisions, and comfortable working in a fast‑paced operational environment.

This role offers flexible working, based from Leatherhead, South Mimms or Dartford, with travel required across the M25 network. Occasional site visits, including night‑time health and safety audits, may also be necessary. A full UK driving licence is required.
