Water isn’t just a resource; it’s the lifeblood of our communities. As we navigate the ambitious demands of the AMP8 regulatory cycle, the choices we make today will define the environmental resilience of Wales and the South West for generations. At Stantec, our water sector teams across Cardiff, Bristol, Taunton, and Exeter are growing rapidly. We are moving beyond standard engineering to deliver narrative-led, sustainable solutions for the region's major utility frameworks. To achieve this, we are looking for passionate Mechanical Engineers to join our collaborative, award‑winning team. If you want to design with community in mind and tackle the realities of climate change and water scarcity head‑on, your next chapter starts here.
About the Role
This is an invitation to bring your expertise to a team that influences the entire project lifecycle. Whether you are based in Wales or across the South West, you won’t just be sitting behind a desk; you will be an integral part of transforming ideas into reality. Your work will span from early‑stage feasibility and innovative optioneering right through to detailed design, collaborative 3D modeling, and on‑site construction support. You will act as a pivotal technical bridge—collaborating closely with Project Managers, clients, supply chain partners, and multidisciplinary design teams to deliver high‑quality, resilient water and wastewater infrastructure.
Your Impact
- Engineering Excellence: Designing and sizing complex pumping and aeration systems, producing robust technical specifications, and shaping Piping & Instrumentation Diagrams (P&IDs) and General Arrangement drawings.
- Collaborative Innovation: Bringing designs to life by actively contributing to technical workshops, collaborative planning sessions, and critical safety reviews (including HAZOPs and ALMs).
- Mentorship & Growth: For our more senior engineers, your impact will multiply as you provide technical leadership, guiding and inspiring the next generation of junior engineers within the team.
- Community Resilience: Assessing existing site infrastructure to unlock capacity, improve water quality, and help our clients meet their environmental commitments.
