With an ambitious £2.3 billion capital investment in AMP8, we are revolutionising infrastructure, sustainability, and digital transformation to protect the environment and support growing communities.

Location: Peterborough / Anglian Water sites

As a Site Manager, you will lead site-based delivery activities on complex infrastructure projects, ensuring construction works are delivered safely, efficiently, and to a high standard.

What You’ll Be Doing

• Manage and coordinate site activities in line with the construction programme, including subcontractor performance, resources, and materials.
• Lead by example in ensuring all safety, quality, and environmental management systems are adhered to and embedded on site.
• Support project handover and ensure all works are completed to a safe-to-operate (STO) standard at DM4.
• Maintain site compliance with assurance requirements (CSIR, CEIR, CQIR), working alongside the Delivery Assurance Manager.
• Monitor and manage budgets in coordination with the Cost Manager; approve site expenditure, timesheets, and GRNs in line with governance.
• Review and approve subcontractor RAMS, manage site requisitions, and ensure plant and materials are utilised efficiently.
• Take ownership of the rework list, ensuring timely resolution and submission for construction assurance.
• Collaborate with the Project Delivery Team to support programme, cost and quality reporting, and risk management.
• Support change management processes and accurate use of CCMS for cost control and purchasing.
• Liaise with Anglian Water operations staff to ensure seamless asset transition and operational readiness.
• Lead and motivate the site team, promoting a culture of accountability, collaboration and continuous improvement.

About You

We’re looking for an experienced and confident Site Manager with strong leadership skills and a solid background in infrastructure delivery, ideally in the water or utilities sector.

You Will Bring

• Demonstrable experience managing large-scale construction projects with a value of £20 million or more, preferably within the infrastructure or regulated utility sectors.
• A proven track record of successfully delivering complex site operations in line with time, cost and quality targets.
• Strong understanding of health, safety, environmental and quality standards in a live site environment.
• Experience managing subcontractors and supply chain partners to meet programme objectives.
• Commercial awareness and confidence in managing site budgets, cost reporting, and procurement systems.
• Familiarity with project assurance and governance processes, including change control and risk mitigation.
• The ability to lead, engage, and develop site teams, while maintaining excellent stakeholder relationships.
