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.

At @one Alliance, you’ll be part of a dynamic, forward‑thinking team that is shaping the future of the UK’s water infrastructure. We offer a collaborative and innovative working environment, where your expertise will be valued and your ideas will drive meaningful change.
