• Deliver flood risk assessments, drainage studies, and catchment investigations
• Evaluate flood alleviation options, nature-based solutions, and resilience measures
• Work across river, surface water, sewer, and integrated catchment systems
• Integrate modelling outputs with GIS, asset data, monitoring information, and wider spatial datasets
• Support major programmes focused on flood risk management, drainage strategy, wastewater resilience, and climate adaptation
• Translate complex modelling results into clear recommendations for clients and stakeholders
• Provide technical guidance and mentorship to junior team members
• Contribute to innovative approaches including digital twins, automation, real-time data, and emerging analytical techniques
• Support bids, business development, and client engagement

• Digital twins, automation, scripting, or data analytics
• Integrating modelling with monitoring, remote sensing, or geospatial data
• Chartered status or working towards Chartership
• Nature-based solutions and catchment-scale flood resilience
• Move beyond traditional flood modelling and work at the forefront of flood risk intelligence and catchment resilience
• Work on high-impact projects for water companies, local authorities, infrastructure clients, and regulators
• Combine technical modelling with GIS, digital innovation, and strategic decision-making
• Opportunity to influence how major organisations understand and manage flood risk
• Join a growing team where innovation and new ideas are actively encouraged
