We’re looking for an experienced Senior Supervisor (Mechanical) to join our team on a landmark water infrastructure program in Canberra.
This is a rare opportunity to be part of a long-term, collaborative delivery partnership focused on upgrading and expanding critical wastewater infrastructure to support the region’s future growth and sustainability.
Seymour Whyte, together with Vinci Grande Projects and Beca, has been chosen by ICON Water to deliver the Design and Construct upgrade of the Lower Molonglo Water Quality Control Centre - the ACT’s main wastewater treatment facility and the largest of its kind in inland Australia. This four-year project will modernise the plant’s waste handling systems, support future growth, and prepare for potential changes to air emission standards. Located near central Canberra, the upgrade will strengthen and future-proof critical infrastructure for the region.
As a Senior Supervisor you’ll play a key role in delivering complex mechanical installations and ensuring works are executed safely, efficiently and to a high standard.
You’ll be responsible for leading crews and subcontractors across mechanical scopes such as treatment systems, pumps, pipelines, processing equipment and associated infrastructure.
