Senior Hydraulic Modeller

Senior Hydraulic Modeller

Calibre Search are working in partnership with a well-established, multidisciplinary Environmental and Engineering Consultancy specialising in flood risk, hydrology, geomorphology and climate resilience. The organisation has built an excellent reputation for delivering technically robust and innovative solutions that help clients and communities better understand and manage environmental risk in a changing climate.

Operating as part of a wider group of Environmental, Engineering and Risk Management businesses, the consultancy combines scientific expertise with advanced technology to provide forward-thinking approaches to flood and environmental risk management. Their teams work collaboratively across environmental planning, engineering design, water management and data science to deliver projects that support sustainable development and long-term climate resilience.

With a strong and growing pipeline of work across the UK, they are now looking to appoint an experienced Hydraulic Modeller to join their expanding team. This opportunity is well suited to someone already established within flood risk and hydraulic modelling who is looking to play a more senior technical role within complex and nationally significant projects.

The successful candidate will join a collaborative and highly technical team delivering a wide variety of modelling studies. Projects range from detailed site-based flood risk assessments through to catchment-scale modelling, strategic flood risk management plans and climate resilience programmes supporting government agencies, infrastructure providers and local authorities.

Working closely with engineers, environmental scientists and data specialists, you will play a key role in developing robust modelling evidence that informs flood management strategies, infrastructure design and climate adaptation solutions.

The role will involve:

• Building, calibrating and running hydraulic models for flood risk and water management projects
• Producing high-quality modelling outputs and technical analysis
• Interpreting model results and supporting the development of practical engineering and environmental solutions
• Collaborating with multidisciplinary teams including engineers, environmental specialists and planners
• Supporting project managers with the delivery of modelling workstreams
• Providing guidance and mentoring to junior modellers within the team
• Contributing to the development of modelling tools, processes and innovation across the business
• Working with specialist data and digital teams exploring new approaches such as automation, AI and machine learning within environmental modelling

Candidates will typically demonstrate the following:

• A degree in Environmental Science, Geography, Civil Engineering, Mathematics or a related discipline
• Strong experience working within flood risk and hydraulic modelling environments
• Proficiency using industry-standard modelling software such as Flood Modeller, HEC-RAS, InfoWorks ICM, MIKE+ or TUFLOW
• Experience applying 1D, 2D and integrated 1D/2D hydraulic modelling techniques across a variety of rural and urban catchments
• Strong GIS capability using tools such as ArcGIS or QGIS, alongside experience working with terrain and geospatial datasets
• A solid understanding of UK flood risk policy, modelling guidance and regulatory frameworks

The following experience would be advantageous but is not essential:

• Knowledge of hydrological assessment methods, including FEH approaches
• Experience using Python, R or other coding tools for modelling or data analysis
• Exposure to advanced modelling techniques, including Computational Fluid Dynamics (CFD)
• Experience mentoring junior modellers or engineers
• Experience managing technical work packages or supporting client-facing project delivery

The consultancy places a strong emphasis on professional development and supporting long-term career progression. Staff benefit from structured training programmes, access to generous development funding and support toward professional qualifications including chartership. They also promote a positive and supportive working culture with a strong focus on wellbeing, flexible working and maintaining a healthy work-life balance. This represents an excellent opportunity for an experienced Hydraulic Modeller looking to join a respected consultancy working on impactful projects that directly support flood resilience, environmental protection and sustainable infrastructure.
