• Support the integration of water system models such as Aquator, WEAP or Pywr


• Provide line management, mentoring and technical guidance to junior staff


• Ensure quality assurance and best practice on project delivery

What We’re Looking For:

• Degree in hydrology, civil engineering, geography, environmental science, or a related field


• Chartered (or working towards chartership) with a recognised professional institution


• Strong technical background in low flows, hydrological modelling, and climate resilience


• Excellent communication skills and the ability to manage multidisciplinary teams


• Strong leadership qualities and a track record of technical project delivery

Desirable:

• Experience guiding junior consultants or managing small teams


• Familiarity with UK water resources planning and regulatory processes


• Interest in digital tools and innovation in hydrology

What’s on Offer:

• Flexible grade and salary depending on experience (Principal, Associate or Senior Associate level)


• Private medical insurance and full health support


• Strong pension and life assurance package


• 33-35 days annual leave (with option to buy/sell)


• Enhanced family, parental, and carers’ leave


• Professional development, paid memberships and structured career progression


• A highly flexible, inclusive work environment with remote options available

We welcome applications from individuals with diverse backgrounds and offer support and adjustments where needed throughout the recruitment process. If you’re a technically strong hydrologist ready to lead impactful projects-and want the flexibility to shape how and where you work-we’d love to hear from you.
