    Job Details

    The Senior Mining Engineer is responsible for developing and managing short-, mid-, and long-range mine plans at an open-pit copper operation processing approximately 60,000 tons per day (tpd) of leach material. This role ensures optimized mining sequences, haulage, and leach cycle placements, cost-effective operations, safe working conditions, and efficient leach pad utilization, while mentoring junior staff and coordinating with operational and technical teams.

    Key Responsibilities:

    + Develop and manage daily and weekly mine plans for material extraction, including designing, drill & blast sequence, haulage, and leach pad placements.

    + Monitor and reconcile operational performance against short-range plans; implement corrective actions as needed.

    + Coordinate closely with operational teams (mining, drilling/blasting, pad stacking, metallurgy) to ensure smooth execution of daily plans.

    + Prepare rolling monthly and quarterly forecasts, and annual mining budgets (tonnage, grade, stripping ratios, equipment utilization, and reagent usage).

    + Optimize pit sequencing, leach pad lift designs, haulage routes, and waste management strategies.

    + Identify and recommend operational improvements to increase productivity and cost efficiency.

    + Collaborate with Geotechnical Engineering on slope and dump stability

    + Model and steward site water/acid inventories and solution‑management infrastructure

    + Generate and regularly update life-of-mine plans based on evolving pit designs, geologic models, and economic parameters.

    + Conduct pit optimization studies using industry-standard software.

    + Provide technical analysis for strategic projects, expansions, and regulatory filings

    + Initiate Kaizen/LEAN projects that deliver quantified $/t mined savings

    + Mentor and support junior mine planning engineers, facilitating their professional growth.

    + Interface effectively with cross-functional teams, including geology, metallurgy, Mine Operations, environmental, and safety.

    + Promote and enforce high standards of safety and environmental responsibility across mine planning activities.

    + Education & Certification: Bachelor's degree in Mining Engineering

    + Minimum 5 years' experience in open-pit mining engineering with direct experience or responsibility for short-, mid-, and long-range mine planning.

    + Specific experience in large-scale copper operations utilizing heap or dump leach processes is highly desirable.

    + Proficiency in mine planning software: MineSight/Hexagon, including Planner, MPSO and pit optimization tools.

    + Proficiency with fleet‑management/dispatch systems and data analytics tools (SQL, Python, Power BI)

    + Strong knowledge of haulage modeling software

    + Excellent analytical and problem-solving abilities with expertise in mine scheduling and cost optimization.

    + Strong interpersonal, leadership, and communication skills; capable of clearly presenting technical data to various stakeholders.
