Start here. Grow here.

You will lead mechanical engineering work packages for underground copper and gold hard-rock mining projects. The role covers studies, trade-off assessment, detailed design, procurement, construction support, commissioning and operational readiness.

You will take ownership of complex materials-handling and fixed-plant scopes, including crushing, conveying, transfer systems, pumping, dewatering, dust management, ventilation interfaces and associated underground infrastructure.

Here is what you will do:

• Lead the development and delivery of mechanical engineering design packages for underground mining and materials handling projects in accordance with Australian Standards, client specifications, and applicable mining legislation;
• Perform conveyor system design and analysis using Sidewinderand Belt Analyst Conveyor Design Software, including conveyor sizing, power calculations, dynamic analysis, transferchutedesign coordination, and design optimisation;
• Apply formal bulk solids handling and flow principles to the design of bins, chutes, feeders, transfer stations, and ore handling systems to ensure reliable operability and maintainability;
• Develop engineering calculations, equipment specifications, datasheets, scopes of work, technical evaluations, and design reports for mechanical systems and equipment;
• Lead the design and integration of crushing, screening, conveying, pumping, dewatering, dust management, and ventilation systems associated with underground and surface mining operations;
• Develop practical solutions for dust suppression, dust extraction, and material containment in abrasive and high-throughput ore handling environments;
• Contribute to mine ventilation and ventilation-on-demand (VOD) infrastructure design, including coordination with ventilation specialists and integration of mechanical services within underground environments;
• Coordinate multidisciplinary interfaces including civil, structural, electrical, process, and geotechnical requirements to deliver integrated engineering outcomes;
• Conduct technical reviews, risk assessments, HAZOPs, constructability reviews, and design verification activities;
• Provide technical leadership, mentorship, and guidance to graduate and intermediate engineers and designers;
• Liaise directly with clients, vendors, project managers, and site personnel to manage technical deliverables, resolve engineering queries, and support project execution;
• Support procurement, tender evaluations, construction activities, commissioning, and operational readiness as required.

Here’s what we’re looking for:

• Strong first-principles engineering capability across materials handling, bulk-solids flow, rotating equipment, fluid…
