Job Description: 

Mott MacDonald is a unique company to work for, combining heritage, vision and values into an ethos that encourages innovative thinking and career progression in technical, management or commercial/client-facing directions, or a combination thereof. Our employee-owned structure enables us to shape our own future and pursue social outcomes in everything we do. It also puts our people, their development, and their wellbeing at the heart of our business. With us, you will have control of your own career path, which we will support through mentoring and training, but above all by giving you the opportunities to face new challenges and take more responsibilities.  

We have a strong record in tackling the challenges affecting the water environment, including river catchments, from the source to the sea and water on the surface and underground. Within the current climate emergency, we are experts in understanding the impact of climate change on water availability and work with major UK water companies and international clients to ensure future demand for water is met and renewable energy schemes are feasible while preserving the environment. We contribute to improving the ecology of our rivers, aquifers and coastal areas by establishing the impact of abstractions and discharges and by defining sustainable ways of reducing pollution using nature-based solutions. We are also supporting the Environment Agency, local authorities and major infrastructure developers to quantify the risk of flooding and to design the most effective flood protection measures including natural flood management. 

Flood Risk Specialist  

Protect Communities. Shape Resilience. Drive Change. 

Join a team where your work helps safeguard lives, protect ecosystems, and build climate-resilient futures. As a Graduate Flood Risk Specialist, you’ll be at the forefront of tackling one of the most pressing global challenges—flood risk—through innovative, data-driven, and nature-based solutions. 

Our Water Consultancy Division is a hub of technical excellence, offering diverse opportunities to work on river, surface water, and coastal flood risk projects. You’ll receive full training in industry-standard hydraulic modelling and hydrology, and contribute to projects that support environmental regulators, local authorities, and infrastructure developers. 

What You’ll Be Doing 

• Model with impact: Use 1D-2D hydraulic modelling tools to simulate flood scenarios and develop actionable insights. 
• Analyse and verify: Build and validate models, and use GIS tools to manipulate and analyse hydrological and flood risk data. 
• Assess and advise: Contribute to Flood Risk and Consequence Assessments, helping shape planning and mitigation strategies. 
• Design solutions: Support the development of flood risk management strategies, including pioneering Natural Flood Management (NFM) approaches. 
• Collaborate and learn: Work on fluvial and coastal risk projects, attend site visits, and engage in team and client meetings. 
• Grow with purpose: Be part of our Early Careers Professionals Network, gaining exposure to technical, commercial, and client-facing aspects of project delivery. 

Environmental Hydrologist  

Restore Rivers. Protect Ecosystems. Empower Communities. 

Join a team where your work helps safeguard the health of our water environment and supports nature-positive solutions for a sustainable future. As a Graduate Environmental Hydrologist, you’ll be part of a legacy of catchment management excellence—tackling challenges like nutrient pollution, pesticides, and habitat degradation through data-driven insights and collaborative innovation. 

Our Water Consultancy Division leads the way in environmental hydrology, supporting regulators, authorities, and infrastructure developers with impactful solutions. From traditional engineering to pioneering nature-based approaches, your contributions will help shape resilient ecosystems and healthier communities. 

What You’ll Be Doing 

• Analyse and assess: Conduct water quality impact assessments of abstractions and discharges, and evaluate solutions to improve water quality. 
• Design with nature: Appraise traditional and nature-based solutions (NbS), including river restoration options for heavily modified water bodies. 
• Model and manage: Support hydrological assessments, water quality modelling, and catchment management planning. 
• Visualise and communicate: Use GIS tools for data manipulation and visualisation, and contribute to stakeholder engagement. 
• Explore and learn: Participate in geomorphological studies, NbS screening, and options appraisal, gaining exposure to a wide range of environmental challenges.
