About the role

Staff Mining Engineer with 10+ years of hard-rock open pit mining experience, leading mine planning, field execution, and continuous improvement to translate designs into safe, practical, and efficient mining operations.

Responsibilities

  • Lead safety and uphold standards. Demonstrate visible safety leadership in the field. Incorporate operational risks, geotechnical requirements, and applicable standards into mine designs, schedules, and execution practices.
  • Develop mine plans and schedules. Prepare and maintain shift, daily, weekly, monthly, and rolling medium-term plans aligned with longer-term mine objectives, production targets, and available resources.
  • Turn plans into executable operations. Translate designs and schedules into clear work instructions, priorities, and field deliverables. Confirm access, working areas, equipment, blast readiness, and material destinations with operations teams.
  • Design practical mining layouts. Develop and update pit, bench, ramp, haul-road, stockpile, and waste-dump designs that meet safety requirements and support efficient equipment movement and mining sequences.
  • Plan ore and waste movement. Coordinate ore extraction, waste stripping, stockpiling, and material routing. Work with geology and processing teams to manage feed requirements, dilution, ore loss, and material tracking.
  • Optimize drilling and blasting. Improve blast designs and sequencing to achieve safe blasting, suitable fragmentation, efficient loading and hauling, and competitive costs. Coordinate drill-and-blast readiness with the production schedule.
  • Improve equipment productivity. Evaluate equipment capabilities, loader-truck matching, haul cycles, availability, utilization, and delays. Use realistic production assumptions and work with operations and maintenance to address constraints.
  • Monitor execution and reconcile performance. Compare actual production with the plan, investigate variances, identify root causes, and develop practical recovery plans. Feed operating results back into planning assumptions and schedules.
  • Optimize mining performance. Evaluate alternative designs, sequences, and operating approaches to improve productivity, reduce costs, and maintain ore supply. Use operational data and support improvements in digital planning and automation.
  • Collaborate and develop others. Work closely with operations, maintenance, geology, survey, geotechnical, processing, and software teams. Communicate priorities clearly, share knowledge, and mentor engineers.

Qualifications

  • Bachelor's degree in Mining Engineering
  • 10+ years of experience in the mining industry, including substantial hands-on experience in hard-rock open pit mining operations
  • Expert proficiency in Deswik for mine design, mine planning, and production scheduling
  • Strong experience in short- and medium-term planning, operational mine design, production scheduling, and mine plan execution
  • Demonstrated experience in drill-and-blast optimization and ore and waste planning
  • Strong practical understanding of mining equipment, production rates, haulage, operational delays, and the interaction between planning, operations, and maintenance
  • Proven safety leadership and commitment to high mining industry standards and sound engineering practice
  • Strong analytical, problem-solving, and communication skills, with the ability to work effectively with field crews and multidisciplinary teams
