Job description

We are looking to strengthen our Engineering team in the @one Alliance with an Infrastructure Engineer based in Peterborough, with hybrid working options available.

Join our team as an Infrastructure Engineer and play a key role in shaping sustainable and efficient water and wastewater solutions. You'll be part of a collaborative Design and Build environment, working closely with internal teams and external partners from feasibility through to detailed design. This is a chance to contribute innovative, cost-effective engineering solutions that make a real impact—while growing your expertise in a supportive and forward-thinking setting.

What you’ll be doing:

• Apply engineering knowledge in potable and wastewater design, including pipeline design, and relevant British/Eurocode standards.
• Develop designs from feasibility and optioneering through to detailed design, ensuring technical quality and compliance.
• Understand and incorporate various pipeline construction methods, ancillary components, and GIS tools where applicable.
• Produce and interpret technical drawings and design sketches; contribute to specifications, proposals, and schedules.
• Implement health and safety principles in design, including Design Risk Assessments and Pre-Construction Information (PCI) files.
• Support project delivery by reviewing technical work, maintaining documentation standards, and addressing contractor queries.
• Collaborate closely with internal teams and stakeholders to ensure seamless project interfaces and promote technical innovation.
• Communicate effectively across all levels to uphold design integrity, manage risks, and ensure successful project outcomes.

Experience working on capital projects within the water sector is highly desirable. A degree in Civil Engineering (BEng or MEng/MSc, minimum 2:1) from a recognised university is preferred, though not essential. Strong understanding and practical experience in infrastructure design calculations, including pipework, thrust blocks, manholes, shaft tanks, and attenuation structures, using British Standards, Eurocodes, and industry guidance (e.g., CIRIA, BRE). Familiarity with Design & Build project environments is an advantage. Actively working towards Chartered Engineer status (e.g., CEng MICE) with a relevant professional institution is desirable.
