Junior Mechanical Engineer - Water and wastewater infrastructure

Location - Brisbane or Perth

Support mechanical design for water and wastewater treatment plants, pump stations and associated pipework. Build technical capability through supervised project delivery while contributing accurate calculations, equipment documentation and coordinated design information.

Working with Binnies Australia

We deliver water engineering consultancy for utilities, government and industrial clients, including treatment upgrades, conveyance and mine water projects. You will work with multidisciplinary teams and draw on Binnies and RSK specialists, including colleagues in other offices, to support studies, design and construction delivery.

The role supports direct client commissions and contractor-led design and construct projects. Work includes coordination with suppliers, operators and delivery partners, with site visits and travel as required by the assignment.

Role Responsibilities -

- Review drawings, asset records and vendor information; assist with site surveys, equipment inventories and condition assessments, recording uncertainties for senior review.
- Undertake supervised calculations for pipework losses, pump duties and equipment sizing. Document units, assumptions and sources and seek help when results are uncertain.
- Assist with selection and specification of pumps, valves, screens, blowers, chemical dosing and sludge equipment appropriate to each project.
- Prepare equipment data sheets, valve and equipment schedules, technical specifications and drawing mark-ups; maintain alignment with process duties and project requirements.
- Assist CAD and BIM designers with layouts and pipework arrangements, considering maintenance access, equipment removal, isolation, drainage and safe operation.
- Coordinate assigned interfaces with process, civil, structural, electrical and control engineers. Record actions and resolve comments with the supervising engineer.
