Play a leading role in the delivery of mechanical engineering design packages for underground copper and gold hard rock mining projects. Operating with a high degree of autonomy, you will apply deep technical expertise across the full project lifecycle; from concept through to detailed design and construction support with minimal supervision. You will be a key technical contributor within a multidisciplinary consulting team, taking ownership of complex mechanical design scope including surface and underground material handling, ventilation systems, fixed plant, and associated infrastructure typical of hard rock metalliferous mining environments. Produce and lead the delivery of detailed mechanical designs, equipment layouts, and engineering drawings using AutoCAD, and Advance Steel, ensuring compliance with Australian Standards, client specifications, and applicable mining regulations; Develop and manage 3D plant models and coordinate discipline clash detection using Navisworks or equivalent federated modelling tools; Apply a thorough understanding of underground hard rock mining systems including ore handling (crushers, conveyor systems, ore passes, winders/hoists), dewatering, ventilation on demand (VOD) systems, workshops and fixed plant; Independently interpret geotechnical, civil, and structural interfaces to produce fully coordinated mechanical designs appropriate for underground environments; Manage and control drawing registers, model deliverables, and document workflows; Conduct and lead internal design reviews, checking your own and junior staff work for technical accuracy, constructability, and compliance prior to issue; Provide technical mentorship and guidance to cadet and intermediate designers within the team; Liaise directly with project engineers, project managers, and client representatives to manage design deliverables, resolve technical queries, and ensure on-time delivery; Develop and maintain equipment libraries for underground mechanical equipment. The qualities that help you thrive: Demonstrated ability to work autonomously on complex mechanical design tasks with minimal direction from senior engineers Strong understanding of first-principles mechanical design including plant layout, MHS set out, structural loads, fluid systems, rotating equipment, and materials selection in corrosive or abrasive underground environments Deep familiarity with underground hard rock mining operations, equipment, and the practical constraints of designing for confined, remote, and hazardous environments High proficiency in 3D modelling and 2D drawing extraction with a consistent record of low error rates and thorough self-checking Collaborative and communicative, with the confidence to challenge design assumptions and raise technical concerns constructively Minimum 8–12 years of mechanical drafting and design experience in a CAD environment, with at least 5 years focused on hard rock underground mining (copper/gold preferred) Advanced proficiency in AutoCAD, Advance Steel, and Navisworks experience is essential.
