- Review, assess, and recommend improvements to maintenance and operational practices, and support component lifecycle management and breakdown response coordination
- Identify and develop aftermarket sales opportunities through regular customer engagement and fleet analysis, referring qualified opportunities to the Mining Support Manager to support business growth

- Sound commercial acumen, with the ability to identify and clearly communicate sales and aftermarket opportunities to the Mining Support Manager
- Robust understanding of whole-of-life cost, Fleet Production Cost (FPC) and equipment application, with familiarity with CAT systems (DBS, SIS, ET, SIMSi, TMI) an advantage
- Demonstrated high-level customer relationship management and advanced communication skills
- Proven ability to troubleshoot equipment faults, analyse data and compile reports to drive performance improvement
