About The Position

The Short-Range Mining Engineer plays a key role in producing and updating operational mine plans covering timelines from the upcoming month out to one year. This position ensures that short-term designs are practical, geotechnically sound, and aligned with production targets for an open-pit copper operation processing sulfide ore. Working under the direction of the Chief Mining Engineer, the engineer collaborates extensively with Geology, Survey, Processing, and Operations to convert medium-range strategies into actionable bench-level guidance. The role involves preparing dig-ready designs, sequencing pit progression, managing material routing, and supporting daily production execution. Cross-functional development within the broader mine planning group is expected.

Requirements

Bachelor’s degree in Mining Engineering or a closely aligned discipline.
At least 2 years of professional experience in open-pit mine engineering or mine operations.
Proficiency with Hexagon MinePlan software, including MinePlan 3D, Activity Scheduler, haulage/scheduling tools, MPSO, and related short-term design applications.
Strong technical understanding of open-pit mining practices, including drilling and blasting, ore control processes, pit sequencing, and material handling.
Ability to work effectively in a dynamic production environment and communicate clearly with both field personnel and technical teams.
Strong analytical abilities coupled with solid communication, organization, and problem-solving skills.

Responsibilities

Produce, update, and communicate rolling short-term mine plans (1–12 months), ensuring they reflect production priorities, operational conditions, and the mid-range strategic plan.
Create pit advancement designs such as bench configurations, dig polygons, ore boundaries, and drilling layouts that comply with geotechnical, safety, and operational guidelines.
Partner closely with Drill & Blast engineers to develop spacing, burden, timing, and initiation parameters that promote optimal fragmentation, minimize dilution, and support practical field execution.
Coordinate with Mine Geology to integrate grade control interpretations, ore/waste delineation, and material classifications into daily and weekly dig plans.
Build detailed material movement and routing plans, including directing sulfide ore to the appropriate crushers and stockpile locations while meeting blending and processing specifications.
Prepare operational guidance including haulage instructions, shovel-ready maps, blast clearance diagrams, and related documentation for use by Production and Control Room teams.
Track adherence to the short-range plan by comparing design intent against survey pickups, adjusting schedules and designs to account for ground conditions, equipment utilization, or shifting production needs.
Apply Hexagon MinePlan 3D and related short-term planning tools (e.g., Activity Scheduler, haulage modules) to design, model, visualize, and monitor short-term mining performance.
Participate in routine operational meetings to present progress updates, compliance metrics, and corrective actions for the planning horizon.
Provide inputs to monthly forecasts, budgeting cycles, and reconciliations, ensuring that short-term assumptions and outcomes are accurately captured.
Work alongside Medium-Range and Long-Range Planning teams to support integrated mine scheduling, share feedback on execution, and support cross-training initiatives.
Maintain traceable documentation of assumptions, design changes, schedules, and planning decisions to support transparency, operational learning, and continuous improvement.
