Senior / Lead Mechanical Engineer - Underground Hard Rock Mining

• Lead mechanical engineering design packages for underground mining, materials handling and fixed-plant projects. • Undertake conveyor design and analysis using recognised software such as Sidewinder or Belt Analyst, including sizing, power calculations, dynamic assessment and design optimisation. Apply bulk-solids handling principles to bins, chutes, feeders, transfer stations and ore-handling systems to support reliable operation and maintainability. • Prepare calculations, equipment specifications, datasheets, scopes of work, technical evaluations and design reports. Lead the design and integration of crushing, screening, conveying, pumping, dewatering, dust-management and ventilation-related systems. • Develop practical dust-suppression, extraction and containment solutions for abrasive, high-throughput materials-handling environments. Coordinate civil, structural, electrical, process, controls, ventilation and geotechnical interfaces. • Lead or contribute to technical reviews, risk assessments, HAZOPs, constructability reviews and design verification. Support procurement, vendor engagement, tender evaluation, construction, commissioning and operational-readiness activities. • Mentor engineers and designers and contribute to consistent technical standards and lessons learned.
