About the Role
Join AECOM’s dynamic Water team as a Principal or Associate Flood Forecasting Modeller and play a senior technical role shaping the future of the Water Industry. You will lead teams delivering real-time flood forecasting projects and help expand services with the Environment Agency and other clients. While your primary focus will be flood forecasting, you will also have opportunities to work on wider hydrology and non-real-time modelling projects.

Your responsibilities will include producing and reviewing Flood Forecasting Inception Stage Reports, assessing model quality and hydrometric data, developing and calibrating flood forecasting models such as PDM and Flood Modeller, and conducting hydrological analysis using tools like Flood Modeller, ICM, HEC-RAS, MIKE 11, and FEH methods. You will produce high-quality technical reports documenting model builds and uncertainties, lead and contribute to tenders, mentor team members, build strong client relationships, and stay current with relevant legislation and guidelines.

Become part of a team of around 700 water experts across the UK and Ireland, collaborating on projects from concept to completion. AECOM offers an inclusive and forward-thinking environment with career development opportunities, technical practice networks, AECOM University, volunteering days, and a flexible hybrid working model to support work-life balance. Part-time and flexible working arrangements are also considered.

Experience
- Significant experience in flood forecasting modelling, particularly with Flood Modeller
- Strong knowledge of Environment Agency requirements and preparing models compatible with their Incident Management Forecasting Systems
- Proven ability in applying and calibrating hydrological models such as Muskingum-Cunge and Probability Distribution Model
- Excellent analytical skills with experience processing and analysing hydrometric data including gauge rating reviews

About you
- Self-motivated with the ability to work autonomously and as part of a dynamic, deadline-driven team
- Strong commitment, willingness to learn, and passion for innovation
- Excellent communication and mentoring skills to support team development
- Ability to build strong relationships with clients and colleagues across disciplines

Qualifications
- Bachelor’s degree or equivalent in Civil Engineering or a relevant discipline
- Strong GIS skills (QGIS, ArcGIS and/or MapInfo)
- Practical knowledge of scripting languages such as Python, Anaconda, Ruby, or similar is advantageous
