Laboratory Technician - Asphalt | Hope Valley & Gosnells, WA
Bring your lab experience to Downer and play a key role in the quality of the asphalt behind WA's major infrastructure. This is a hands-on materials testing role that splits your time between our NATA-accredited labs and live project sites, where you'll core and sample the work as it goes down.

We're looking for Laboratory Technicians to join our teams at Hope Valley and Gosnells. The role runs across both the lab and the field: testing asphalt, bitumen and aggregates to make sure every mix meets specification, and getting out on site regularly to core and sample on active projects.
What the job looks like
Test asphalt, bitumen, aggregates and related road construction materials to Australian Standards, MRWA specifications and WA Test Methods
Prepare samples, run tests, record results and maintain accurate records under our NATA / ISO ***** quality system
Head out to site regularly to core and sample on live projects, working alongside paving crews
Monitor asphalt product quality and support quality control across production and paving
Keep lab equipment calibrated, maintained and operated safely
Assist with investigations into product performance and test results as required
Take part in toolbox talks, safety initiatives and continuous improvement
Work collaboratively with production, paving and operational teams
