• Own the review and interpretation of metallurgical test work programs (bench, pilot, and plant-scale), guiding test work strategy and ensuring outcomes translate into robust design criteria
• Act as the senior technical point of contact with OEMs and equipment suppliers on flotation cell selection, sizing, and performance guarantees
• Lead optimisation initiatives for operating plants, including circuit troubleshooting, debottlenecking, and performance improvement studies
• Travel to site to conduct optimisation reviews and diagnostic work, identifying root causes of performance issues and implementing corrective actions
• Manage flotation test work programs end-to-end, including scope development, laboratory/site coordination, scheduling, budget tracking, and reporting
• Deliver site-based training to operations and technical teams on flotation fundamentals, best practice, and troubleshooting
• Apply deep operational experience to ensure designs are practical, maintainable, and aligned with real-world plant performance
• Take ownership of mass balances, equipment sizing calculations, and process design criteria for flotation circuits, signing off on deliverables
• Lead due diligence reviews, technical audits, and studies for clients, presenting findings and recommendations directly
• Represent Ausenco in client-facing discussions, workshops, and technical presentations
• Collaborate with and provide technical input to multidisciplinary project teams (mechanical, controls, piping) to ensure integrated design outcomes
• Contribute to business development, including technical input on proposals and scopes of work
• Support recruitment, technical training programs, and continuous improvement of internal flotation design standards and tools
