Lead Engineer Mechanical (Underground Hard Rock Mining)

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 Sidewinder and Belt Analyst Conveyor Design Software including conveyor sizing power calculations dynamic analysis transfer chute design 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. 

Heres what were looking for:

• Strong first-principles engineering capability across materials handling bulk-solids flow rotating equipment fluid systems and fixed plant.
•  Practical understanding of underground hard-rock operations and the constraints of confined remote and high-risk environments.
•  Able to identify technical risk challenge assumptions constructively and develop fit-for-purpose solutions.
•  Clear communicator with project teams vendors site personnel and clients.
•  Organised and able to manage competing priorities while maintaining quality under programme pressure.
•  Collaborative accountable and committed to mentoring and knowledge transfer.
• Experience using Discrete Element Modelling (DEM) software for bulk material flow analysis transfer chute optimisation and materials handling troubleshooting would be highly regarded;  
• Experience with engineering and modelling software including AutoCAD Navisworks Plant 3D Revit or equivalent platforms;  
• Sound working knowledge of relevant Australian Standards and mining legislation including AS 4024 AS 1418 AS 4041 AS 4100 and WHS requirements.  Equivalent international standards experience with demonstrated adaptability will also be considered.
• Experience working within multidisciplinary EPCM or consulting project environments;  
• Proficiency across Microsoft Office Suite and engineering document management systems. 

Qualifications :

• A bachelors degree in Mechanical Engineering from a recognised institution.
•  At least 9 years mechanical engineering experience including significant exposure to mining bulk materials handling or heavy industry.
• Registered Professional Engineer with a recognised professional body.
•  Demonstrated capability in conveyor systems transfer systems fixed plant and bulk-materials handling.
•  Practical experience using at least one recognised conveyor-design package including Sidewinder or Belt Analyst.
•  Experience producing coordinated deliverables across concept pre-feasibility feasibility detailed design and construction support.
•  Professional fluency in written and spoken English and confidence engaging with international stakeholders.
