Principal Mechanical Engineer - Water Sector

Step into a pivotal role at Stantec where your technical mastery meets the front lines of the challenges facing the water industry today. As a Principal Mechanical Engineer within our South of England Water team, you will be leading the design of mechanical systems that ensure water security and environmental resilience for water companies across the UK and Ireland. Whether you choose to base yourself in Brighton, Ashford, Kings Hill, or Southampton, you are joining a consultancy at the peak of its growth, offering you a high-visibility platform to sharpen your expertise and lead complex, multi-million-pound frameworks.

This position is designed for a technical specialist who thrives on the intricate details of the entire asset lifecycle. You will own the process from initial feasibility studies and rigorous optioneering through to the precision of detailed design and on-site construction support. Your day-to-day will involve conducting deep-dive site surveys and investigations to ensure our engineering solutions are both innovative and robust. You will find yourself at the heart of cutting-edge mechanical design, solving unique efficiency challenges that directly impact our local communities.

Beyond the technical drafting and specification, this role serves as a cornerstone for professional development and mentorship. You will act as the primary technical conduit between project managers, supply chain partners, and contractors, ensuring that sophisticated mechanical requirements are translated into successful, real-world outcomes. As you guide less experienced engineers through the nuances of the water business, you will find a clear and supported path for your own career progression. At Stantec, your growth is fuelled by a collaborative culture and the opportunity to leave a tangible, sustainable legacy across the UK’s water infrastructure.
