• Acting as a technical point of contact for clients and stakeholders, supporting design decisions and contributing to effective project delivery.
• Working collaboratively with hydraulic modellers, surveyors, geotechnical engineers, and other disciplines to develop integrated and buildable solutions.
• Playing an active role in initiatives to reduce Combined Sewer Overflow (CSO) spills, supporting wider business objectives across Cities & Development and Transportation markets.
• Providing technical oversight, mentoring, and support to less experienced engineers, helping to grow capability within the team.
• Leveraging digital tools and data to improve design quality, efficiency, and decision‑making, supporting innovation across the water and infrastructure sectors.

About you:

• A degree in Civil Engineering or a closely related discipline.
• Chartered status with ICE or CIWEM.
• Strong experience in the design and delivery of wastewater and/or surface water infrastructure, ideally within regulated water or infrastructure frameworks.
• Sound knowledge of current UK codes, standards, and best practice, with the confidence to apply professional judgement.
• Experience working within multi‑disciplinary teams and contributing to technically complex projects.
• Proficiency in relevant digital and analysis tools, such as MicroDrainage, InfoDrainage, InfoWorks ICM, Civil 3D, and GIS platforms, with an interest in developing efficient design workflows.
