Job description

The Opportunity

Climate change is reshaping how we think about water. Flood risk is growing, infrastructure is under pressure, and the need for skilled hydrologists and hydraulic modellers who can translate complex data into real-world solutions has never been more pressing.

About the Role

You will join a friendly, collaborative group of over 90 Hydrologists, Hydrogeologists, Water Resources Planners, and Water Quality Scientists, with flexibility to be based from our Edinburgh, Glasgow, Manchester, Leeds, Newcastle, Bristol or Cardiff offices.

Your work will span a wide range of hydraulic modelling projects across the water sector, including 1D-2D flood risk modelling, public water supply resilience studies and support for Local Flood Authorities. Typical projects include modelling new infrastructure in floodplains, eel screen installation assessments, reservoir decommissioning studies and river restoration work, predominantly using Flood Modeller‑TUFLOW packages. Some of this work contributes to nationally significant long‑term water supply resilience programmes across the UK.

You will also have the opportunity to broaden your expertise across hydrology, SuDS design, flood risk appraisal and development planning, with the support of an experienced team around you and the chance to develop junior colleagues as your own skills grow.

Your core technical experience will include 1D/2D hydraulic modelling using Flood Modeller, TUFLOW, or InfoWorks ICM across fluvial, pluvial, or tidal settings; GIS analysis using ArcGIS Pro or QGIS; preparation of Flood Risk Assessments in line with national planning policy; and the production of high‑quality technical reports for a range of audiences.

Beyond the essentials, experience in any of the following would be welcome: hydrological methods such as FEH, ReFH2 and WINFAP; surface water drainage strategies and SuDS design; LLFA studies; natural flood management; or contributions to Environmental Impact Assessments.

Your Impact

The work you do here will help communities become more resilient to flooding, protect public water supplies and support the restoration of rivers and natural systems that have been under pressure for decades. These are not abstract outcomes. They are felt by real people in real places, and your modelling sits at the heart of making them happen.

As you grow in the role, you will also have the opportunity to support and develop junior colleagues, passing on the technical knowledge that makes the difference between good work and great work.

About You

You hold a degree in Civil Engineering, Geography, Environmental Science or a related subject, and you are working towards Chartership with CIWEM, ICE or a similar professional body. You have solid experience delivering hydraulic modelling projects, and you bring good communication skills alongside your technical ability.

You are comfortable working across multiple projects in a collaborative team environment, and you are motivated by the opportunity to keep developing your skills in a supportive setting that genuinely invests in its people.
