Job summary

Gunnison Copper is seeking a Geotechnical Engineer to join the Johnson Camp Mine team in southeastern Arizona. This hands-on, site-based role focuses on monitoring slopes, highwalls, heap-leach facilities, and other geotechnically sensitive areas, with close collaboration with operations, engineering, geology, and safety.

You will manage the geotechnical surveillance program, review monitoring data, and administer TARPs while contributing to rockfall control and risk management.

Qualifications

• Bachelor's degree in Geological Engineering, Geotechnical Engineering, Mining Engineering, Civil Eng with a geotechnical emphasis, or closely related discipline.
• Approximately 3+ years of relevant engineering experience.
• Working knowledge of slope stability, rock mechanics, ground control, and geotechnical risk management.
• Experience collecting, reviewing, and interpreting geotechnical field or instrumentation data.
• Strong analytical and problem-solving capabilities.
• Ability to recognize developing field hazards and exercise sound technical judgment.
• Strong written and verbal communication skills.
• Ability to communicate technical issues with engineers, supervisors, operators, contractors, and mine leadership.
• Willingness to work in an active open-pit mining environment and outdoor field conditions.
• Ability to complete MSHA training and comply with site safety requirements.

Responsibilities

• Manage and execute the site’s geotechnical monitoring and surveillance program.
• Conduct routine inspections of pit walls, highwalls, catch benches, heap-leach facilities, slopes, crests, toes, and other geotechnically sensitive areas.
• Identify and evaluate potential ground-control concerns including cracking, rockfall, raveling, bulging, sloughing, erosion, seepage, ponding, settlement, and unusual deformation.
• Review and interpret geotechnical monitoring data from prism, piezometer, inclinometer, InSAR, LiDAR, and GPS/survey systems.
• Evaluate movement, deformation, and pore-pressure trends against trigger levels.
• Administer Trigger Action Response Plans (TARPs) and escalate conditions requiring action.
• Perform event-driven inspections after rainfall, seismic activity, unusual deformation, seepage, or alarms.
• Evaluate highwall and catch-bench conditions and assist in improving rockfall and ground-control practices.
• Collaborate with Mine Engineering to assess geotechnical effects of blasting, excavation, sequencing, and changing conditions.
• Provide geotechnical support to heap-leach operations, including seepage, slope conditions, water management.
• Assist with planning and installation of additional geotechnical instrumentation.
• Coordinate with external Design Engineer and geotechnical consultants.
• Support geotechnical drilling, investigations, instrumentation installation, and studies.
• Track recommendations and corrective actions through to completion.
• Maintain inspection, monitoring, photographic, and technical records.
• Prepare clear geotechnical reports and performance metrics for mine leadership.
• Participate in Management of Change reviews where operational changes may affect geotechnical conditions.
