Shape the Future of Water – Opportunities for Senior Water Network Engineer/Modellers

The UK water sector is on the brink of its most significant transformation in decades. With the Independent Water Commission (IWC) review and unprecedented investment, this is a once‑in‑a‑generation opportunity to redefine how water and wastewater infrastructure serves communities for the future.

You will play a pivotal role in shaping this future—driving innovation, sustainability, and resilience across the sector. From feasibility and planning to cutting‑edge design, construction management, and long‑term operations, you will help deliver solutions that matter.

Partnering with industry leaders including United Utilities, Anglian Water Water, Thames Water, Severn Trent Water, and Anglian Water, you will take the lead on projects that safeguard essential resources, support communities, and elevate performance standards across the sector.

To support our expanding UK portfolio and future growth ambitions, we are looking for Senior Water Networks Engineers/Modellers to join our team. This hybrid role can be based from any of our UK offices, working as part of our diverse, collaborative, and forward‑thinking UK team.

Our Water Networks teams operate nationwide, delivering expertise across the full spectrum of water and non‑infrastructure projects—from feasibility assessments and optioneering to operational support, optimisation, systems integration, and the development of smart network solutions.

You will have the opportunity to lead a diverse range of projects, including water trading, capital design, water quality modelling, network design, zonal studies, leakage optimisation, and model maintenance. You will apply industry‑leading solutions and be encouraged to introduce innovative approaches. In addition, you will support and mentor local teams while contributing to the continued growth of our UK water business.

This is your chance to influence the future of water. Join us and be part of the transformation. Together, we will make it happen.
