Join our team as an Infrastructure Engineer and play a key role in shaping sustainable and efficient water and wastewater solutions. You'll be part of a collaborative Design and Build environment, working closely with internal teams and external partners from feasibility through to detailed design. This is a chance to contribute innovative, cost-effective engineering solutions that make a real impact—while growing your expertise in a supportive and forward-thinking setting.

What you’ll be doing:
