Marine Water Quality Lead Advisor

We’re looking for a marine water quality specialist who brings strong technical expertise and a solid understanding of the policies and legislation that shape this field. In this role, you’ll provide high quality advice across a diverse range of marine water quality issues—from nutrients, contaminants and ecotoxicology, to suspended sediments and, ideally, modelling.

This is a chance to help shape the strategic direction of NRW’s work on marine and estuarine water quality, particularly within our network of Marine Protected Areas. You’ll ensure our advice (e.g. on management actions, regulation and policy) is grounded in robust evidence, while actively seeking opportunities to strengthen that evidence base through targeted projects. You’ll also play a key role in developing clear, practical guidance for colleagues and developers, working closely with experts across both marine and water quality teams.

You’ll be at the heart of work that includes:

• Identifying and delivering evidence needs for marine water quality, including commissioning research and collaborating with academic partners.
• Developing guidance for colleagues advising on marine developments—from power stations to tidal range energy schemes.
• Providing specialist scientific advice on nutrient management in coastal and marine environments.
• Advising on water quality elements of condition assessments and contributing to effective management actions in Marine Protected Areas.
• Offering strategic, high-level input on water quality to influence major plans and projects led by external organisations.

As an organisation we support flexible working. You will be contracted to the nearest NRW office to your home and a suitable hybrid working pattern will be agreed on appointment. Any regular face to face meetings or training will be planned in advance.

Interviews will take place week commencing 27 April 2026 through Microsoft Teams. Successful applicants will be subject to a satisfactory Disclosure and Barring Service Check (DBS) check. Appointments are normally made within 4 to 8 weeks of the closing date.
