Join our Canberra Water team and play a hands-on role in the delivery of one of the ACT's largest and most significant water infrastructure projects.

We're looking for a Site Engineer (Mechanical) to join the team delivering the Lower Molonglo Water Quality Control Centre Upgrade. Working alongside experienced engineers and construction professionals, you'll be involved in the installation and commissioning of critical mechanical systems, coordinate site activities, and help deliver infrastructure that will support Canberra's growing population for decades to come.

This is a fantastic opportunity to gain exposure to a complex wastewater treatment project, work with a collaborative and supportive team, and build your career on a project that will leave a lasting legacy for the Canberra community. Recent graduates with a Mechanical Engineering degree and a strong interest in water infrastructure are also encouraged to apply.

The Project: Lower Molonglo Water Quality Control Centre

The Lower Molonglo Water Quality Control Centre (LMWQCC) Upgrade is a major wastewater infrastructure project in Canberra, ACT, being delivered for Icon Water under its Major Projects Delivery Program. The project is being undertaken through a joint venture between Seymour Whyte and VINCI Construction Grands Projets, alongside design partner Beca HunterH2O, bringing together expertise in large-scale water and civil infrastructure delivery.

The project involves upgrading and expanding the existing wastewater treatment facility to improve treatment efficiency, increase plant capacity, and support Canberra’s growing population. Key works include the construction of a new membrane bioreactor capable of treating up to 97 megalitres of wastewater per day, along with upgrades to critical treatment systems across the plant. Sustainability is also a key focus, with initiatives including renewable energy use, recycled water during construction, and the reuse of on-site materials where possible.
