Are you ready to help us shape the future of the water industry

Join our dynamic and multidisciplinary Water Environment team as a Senior Water Scientist or Hydrologist! At AECOM we are at the forefront of innovation delivering an exceptional portfolio of water programmes and projects through long‑term partnerships with key clients.

We work for clients from across the public and private sectors including the Environment Agency, Natural England, National Highways, Water Companies, NRW, River Trusts and developers, as well as overseas clients. We are involved in major ongoing projects such as the Lower Thames Crossing and we are responsible for the water environment chapters in ESs and WFD assessments.

A selection of our current and recent projects includes:

  • Developing catchment‑wide river restoration plans for water companies.
  • Delivering hydrological reviews and water balance studies for a range of purposes such as determining supply sources and ensuring a canal remains sufficiently full despite its top‑up water supply failing.
  • Design, modelling and installation of Natural Flood Management measures.
  • Developing a modelling approach and running these to inform management decisions such as water‑level dependent designated sites.
  • Delivering improvements through working on water companys Environmental Improvement Programme (WINEP).
  • Designing and helping deliver award fish passes and river restoration schemes.
  • Deriving strategies to deliver catchment water quantity and quality improvements driven by WFD and Local Nature Recovery requirements.

The majority of our work is in the fluvial environment although a significant proportion is also focused on estuaries, lakes and the marine environment.

Our Water Environment team is multidisciplinary with specialists in geomorphology, hydrology, hydro‑ecology, water quality and hydrogeology comprising 60 surface water specialists and a further 25 hydro geologists. All members of the team take an active role in client contact and commercial aspects of our projects. Health, safety and environmental considerations underpin all of our work.

And let’s not forget the perks ’ll enjoy a range of core and personalised benefits designed to support your future and well‑being, customised to fit your lifestyle. Take advantage of career development opportunities, our flexible hybrid working model to ensure a work‑life balance that suits you, technical practice networks, AECOM University and volunteering days.

Qualifications
  • Have a degree (or equivalent) in a relevant subject such as geography, physical sciences, chemistry, maths, engineering, etc.
  • Experience in hydrology (low flows and flood risk), hydromorphology, water quality and/or hydro‑ecology and a strong understanding of aquatic systems.
  • Proficiency in the application of hydrological software and environmental modelling (hydrological/ hydraulic/ water quality/ water resources).
  • Proficiency in GIS software.
  • Report writing skills and the ability to clearly present complex technical information visually and orally to a wide audience.
  • Experience in technical project delivery (from bid preparation and drafting technical proposals to project management).
