• 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
• Liaise directly with project engineers, project managers, and client representatives to manage design deliverables, resolve technical queries, and ensure on-time delivery

• Minimum 8–12 years of mechanical drafting and design experience, with at least 5 years focused on hard rock underground mining (copper/gold preferred)
• Diploma or Advanced Diploma in Mechanical Engineering (or equivalent), with a Bachelor of Mechanical Engineering highly regarded
• Advanced proficiency in AutoCAD, Advance Steel, and Navisworks experience is essential.  Revit and Plant 3D would be highly regarded
