Principal Process Engineer - Clean Water

The south of England is one of the most water-stressed regions in the country, and the strategic decisions being made now will determine how communities access clean, safe water for decades to come. As a Senior Principal, the technical judgements you make and the solutions you champion will carry real weight - influencing investment decisions, informing utility business plans, and helping to future-proof treatment systems against emerging threats. This is engineering leadership where the stakes are high and the outcomes are visible.

You're a Chartered process engineer with deep, demonstrable expertise in clean water, whether your background is rooted in design, science or operations. You bring a strong track record of leading complex projects and the credibility to act as a trusted technical authority with clients, partners and colleagues alike.

You're curious about innovation and genuinely motivated by applying best practice to difficult problems - whether that's improving existing asset performance through on-site testing or developing long-term strategic solutions to resource scarcity. You thrive in a collaborative environment and you understand that at Senior Principal level, your impact on the people and culture around you is just as important as your technical contribution.

Experience across water catchment, resource planning, treatment design or emerging pollutant challenges would all be relevant here. Most importantly, you're someone who wants to help shape the future of clean water in the south of England -- and beyond.
