About the role

Water quality has been established as an area of APEM expertise for many years, but as our team expands we are looking to enhance our modelling capacity. You will work within a dynamic team of aquatic environmental scientists with cross-cutting expertise in ecology, hydrology, geomorphology, water quality, fisheries and natural and social capital, to deliver a range of projects for the UK water and energy industries, and their environmental regulators. The purpose of the role will be to enhance our ability to provide modelling approaches and outputs, as required in particular by the water and construction industries. The role will require the application of modelling packages (river, lake and/or coastal), in particular those recognised and used by regulatory authorities, and contributing to the identification of new modelling approaches. You will also work on water quality monitoring and environmental assessment projects, such as Drought Plan environmental assessments,

Key features of the Senior Consultant role will be managing a range of projects to ensure the delivery of high-quality outputs within budget. This role will also require contributing to or leading the production of competitive tenders and marketing our modelling capabilities to current and potential future clients.
