Process Engineer - Water Sector

Clean, safe water is something most people rarely think about, yet behind every treatment works is a team of engineers solving some of the UK's biggest environmental and infrastructure challenges. At Stantec, our Process Engineers are helping water companies deliver cleaner rivers, more resilient water supplies and sustainable treatment solutions that will serve communities for generations to come.

We're looking for a Process Engineer to join our growing Water team based in High Wycombe or Reading.

In this role, you'll contribute to the delivery of projects across the full project lifecycle, from feasibility and optioneering through to detailed design, commissioning and operational support. You'll work closely with multidisciplinary teams, clients and contractors to develop practical, sustainable process solutions that improve treatment performance and deliver long-term value.

• Undertaking site visits, investigations and process performance assessments.
• Working collaboratively with multidisciplinary design teams to deliver integrated engineering solutions.
• Supporting client engagement by translating operational challenges into effective engineering solutions.

As part of Stantec's integrated Water business, you'll contribute to projects that reduce environmental impact, improve river water quality and strengthen the resilience of critical infrastructure. You'll also have the opportunity to develop your technical expertise, work towards Chartership and help shape innovative solutions that support the future of the water industry.
