The opportunity
A drawing can tell you what needs to be built. Experience tells you how to actually build it.
We're looking for a
Mechanical Construction Supervisor
who can bring both.
Working across water and wastewater construction projects, you'll take charge of mechanical work fronts, coordinate crews and subcontractors and make sure the right people, plant and materials are lined up before they're needed.
You'll own the two-week lookahead, stay close to what's happening in the field and work alongside Engineers and the Superintendent when technical or delivery challenges arise.
For an experienced Mechanical Fitter who has made the move into supervision, this is a chance to put that trade knowledge to good use while taking on greater ownership of project delivery.
What you'll do
Run mechanical construction activities across water and wastewater projects
Lead crews and subcontractors through the day-to-day delivery of works
Own the two-week lookahead, spot potential delays and deal with them early
Coordinate labour, plant, equipment and materials so work fronts are ready to go
Work with Project Engineers to resolve design and constructability issues
Complete field quality inspections and support ITPs, ITRs and commissioning activities
Keep site records, diaries, photos and reporting accurate and up to date
Lead pre-starts and make sure SWMS, risk controls and protected work practices hold up in the field
What we offer
Permanent opportunity working across essential water infrastructure




A role where your mechanical and construction experience carries real weight
Variety across construction, quality, commissioning and project delivery
Suite of Downer benefits, including health and wellness initiatives
Opportunity to continue building your career beyond frontline supervision
What we're looking for
Minimum 5 years' supervisory experience within water and wastewater
Mechanical Fitter trade qualification highly regarded
Wastewater treatment plant experience will be highly regarded
Strong construction background with experience planning, setting up and executing works
Confidence managing subcontractors and site-based crews
Experience with construction programming, quality control and design issue resolution
Frontline Management qualification or equivalent
Someone who notices the problem
before
it becomes tomorrow's delay
