Senior Hydrologist | Flood Hydraulic Modeller

Senior Hydrologist | Flood Hydraulic Modeller

Stantec is seeking a Senior Hydrologist – Flood Hydraulic Modeller to join our growing Hydrology and Flood Risk discipline within the Water Environment team. You can be based in one of our Edinburgh, Glasgow, Manchester, Leeds, Newcastle, Bristol, or Cardiff offices, working alongside over 90 Hydrologists, Hydrogeologists, Water Resources Planners, and Water Quality Scientists.

This role offers the opportunity to work on a wide range of hydraulic modelling projects, including 1D–2D flood risk modelling and Strategic Resource Options (SRO) assessments. Typical project work includes modelling new infrastructure in floodplains, eel screen installation assessments, reservoir decommissioning studies, and river restoration – predominantly using Flood Modeller‑TUFLOW packages. Some programmes involve nationally significant SRO work, contributing to long‑term water supply resilience and security across the UK.

You will play a key role in delivering sustainable, climate‑resilient flood risk and drainage solutions, with opportunities to also work across hydrology, Sustainable Drainage Systems (SuDS) design, flood risk appraisal, and development planning support.

As a senior team member, you will help shape our capability – mentoring junior colleagues, sharing technical expertise, and driving continuous improvement across project delivery and quality assurance.

You will hold a degree in Civil Engineering, Geography, Environmental Science or a related subject, and be Chartered or working towards Chartership with CIWEM, ICE or a similar body.

You’ll bring a strong track record in delivering and managing hydraulic modelling projects, combining technical expertise with leadership, communication skills, and the ability to foster trusted client relationships. You’ll be comfortable managing multiple complex projects, supporting business development, and helping steer the future of our flood risk and water environment services.
