As the Lead Underground Paste Backfill Engineer you will be responsible for the overall technical leadership, management, and successful delivery of the underground paste backfill scope. The role serves as the primary interface between the surface paste plant, underground mining operations, engineering disciplines, construction, commissioning, and the Owner's team. The position provides both engineering management and subject matter expertise for underground paste reticulation systems, ensuring safe, reliable, and cost-effective project execution. 

Your Impact

Engineering Leadership & Management

• Lead the planning, execution, and delivery of all underground paste backfill engineering activities.
• Manage multidisciplinary engineering teams, consultants, and specialist resources.
• Monitor engineering progress, budgets, forecasts, schedules, and deliverables.
• Coordinate interfaces between mining, process, mechanical, piping, electrical, controls, geotechnical, civil, and construction teams.
• Support project controls, risk management, change management, and reporting activities.

Underground Paste Backfill Technical Leadership

• Serve as the technical authority for underground paste backfill systems, including distribution piping, boreholes, valves, pumping systems, barricades, and stope delivery infrastructure.
• Establish and maintain design criteria, operating philosophies, and technical standards.
• Lead design reviews, constructability reviews, HAZOPs, and risk assessments.
• Ensure integration between the surface paste plant and underground distribution network.

Construction & Field Engineering Support
