Job description

Job Description

We’re looking for a Principal or Associate to join our growing Water team. You’ll play a senior technical role, leading teams to deliver real‑time flood forecasting projects, while helping to expand our services with the Environment Agency and beyond.

Although your primary focus will be on flood forecasting, you’ll also have opportunities to work on wider hydrology and non‑real‑time modelling projects.

What you’ll do

• Produce and review Flood Forecasting Inception Stage Reports, including assessing the quality of existing models and hydrometric data.
• Develop, calibrate, and check flood forecasting models (e.g. PDM, Flood Modeller).
• Carry out non‑real‑time modelling and hydrological analysis using tools such as Flood Modeller, ICM, HEC‑RAS, MIKE 11, and FEH hydrological methods.
• Produce and review high‑quality technical reports, documenting model build and associated uncertainties.
• Lead and contribute to tenders for key clients.
• Mentor and support team members in their professional development.
• Build strong relationships with clients and colleagues across disciplines.
• Stay up to date with legislation and guidelines relevant to our services.
• Use AECOM’s project management systems to deliver high‑quality outputs on time and within budget.

Why Join Us

• Be part of a dynamic team that tackles challenging and impactful water projects.
• Work alongside industry‑leading professionals and thought leaders.
• Engage in a collaborative and inclusive work environment.
• Access to continuous learning and development opportunities.
• Competitive salary and comprehensive benefits package.
• Enjoy the flexibility to work in a way that fits your lifestyle while supporting a healthy work–life balance.

Qualifications

Significant experience in flood forecasting modelling (Flood Modeller). Strong knowledge of Environment Agency requirements, including preparing flood forecasting models compatible with their Incident Management Forecasting Systems. Proven ability in applying and calibrating hydrological models in flood forecasting (e.g. Muskingum‑Cunge, Probability Distribution Model). Excellent analytical skills, with experience in processing and analysing hydrometric data, including gauge rating reviews. A Bachelor’s degree (or equivalent) in Civil Engineering or another relevant discipline. Strong GIS skills (QGIS, ArcGIS and/or MapInfo). Practical knowledge of scripting (Python, Anaconda, Ruby, or similar) would be an advantage. You will also be self‑motivated with an ability to work both autonomously where required, with a strong sense of commitment, a willingness to learn and a desire to work in a dynamic deadline‑driven team environment.
