Process Engineer - Water Sector

Ready to move beyond your graduate programme and lead the next wave of sustainable water solutions?

You’ve built a strong foundation in process engineering. Now, it’s time to accelerate your career and apply your expertise to the world’s most urgent water challenges. At Stantec, we’re not just designing treatment plants; we’re crafting a resilient future, from source to tap and drain to river.

The Stantec Story: Progress, Impact, and Opportunity

This is your opportunity to join a top-tier global team consistently recognised for its commitment to sustainability and culture. We’re seeking Ambitious Process Engineers – whether your passion lies in cleanwater resilience or wastewater recovery and environmental protection – who are ready to take on more responsibilities and drive innovation. The role will be based from our offices in Southampton & Brighton.

The Role: Process Engineer

You will join our integrated, national team, working on high-impact projects that span the entire water cycle across the UK & Ireland. We’re looking for engineers who are ready to transition from foundational roles to project leadership and technical specialisation.

• The Cleanwater Journey: Help secure long-term water supply through strategic resource options (SROs), design state-of-the-art treatment facilities, and pioneer source-to-tap solutions for emerging contaminants like PFAS.
• The Wastewater Journey: Focus on achieving ambitious environmental goals, designing advanced treatment for nutrient removal, optimising asset performance, and implementing schemes that champion resource recovery (energy, heat, and materials).

Your progression won’t be linear-it will be bespoke. We see this role as a clear pathway to becoming a Chartered Engineer, a recognised technical specialist, or a future projectleader. You’ll be mentored by industry leaders and given the autonomy to take ownership of challenging work.

Your Day-to-Day Impact

You will be involved in the full project lifecycle, operating as a key technical contributor:

• Technical Excellence: Lead process design development, perform hydraulic analysis, develop mass balance models, and prepare technical reports and specifications.
• On-Site Experience: Conduct site investigations, lead asset optimisation studies, and perform essential on-site test work (e.g., jar testing, pilot plant trials).
• Client Collaboration: Work directly with UK water utility clients, helping to shape business plans and translate strategic needs into viable engineering solutions.
• Global Networking: Engage with our “one team” global community, sharing knowledge and applying international best practices to local challenges.

About You

• Demonstrable process engineering experience gained through a formal graduate programme (or equivalent relevant experience) in the water sector, with exposure to either cleanwater or wastewater specialisms.
• A collaborative spirit and a passion for working as part of an integrated, supportive team.
• A drive to apply innovation and industry best practice to deliver high-value, sustainable outcomes.
