ASARCO Ray Mine is seeking an enthusiastic Geotechnical Engineer – Slope Stability, to be part of a dedicated team focused on supporting safe, reliable copper production at a world‑class porphyry deposit. The Geotechnical Engineer plays a critical role in enabling safe and efficient ore extraction by providing continuous highwall monitoring (e.g., radar, prisms, piezometers), rockfall hazard assessment and control, and practical slope design input at an autonomous‑haulage, high‑tonnage open‑pit copper mine processing both sulfide and oxide ores. Reporting to the Chief Engineer, this position ensures operating decisions are informed by real‑time monitoring data, geotechnical models, and field validation, and that TARPs, stand‑offs, and depressurization strategies are implemented and aligned with mine plans. The Geotechnical Engineer is instrumental in linking and integrating geotechnics with operations, mine planning, dewatering, and tailings - conducting routine TSF inspections and communicating clear, actionable geotechnical guidance - to drive site‑wide risk reduction and value generation.
Responsibilities:
- Deployment, QA/QC, and oversight of slope‑monitoring systems (prisms/total stations, slope radar, LiDAR/UAV photogrammetry, vibrating‑wire piezometers, automated TDR, extensometers) and interpretation of monitoring data.
- Establishment and maintenance of trigger levels and a Trigger‑Action‑Response Plan (TARP); provide on‑call geotechnical support and direct operating controls (stand‑offs, barricades, traffic re‑routes) during movement events.
- Rockfall and bench‑scale stability analyses (kinematic, limit‑equilibrium, and discontinuum as needed); design of catch berms, and attenuator systems; stewardship of the Rockfall Management Plan.
- Reporting and interpretation of geotechnical data and field observations; maintain a single source of truth in the site geotechnical database; produce concise daily/weekly/monthly and event reports.
- Assist with and/or oversee the geotechnical design of pit slopes, pushbacks, and geotechnical projects; integrate recommendations with short‑ and medium‑term mine plans.
- Collaborate with dewatering/hydrogeology on pore‑pressure management; plan, track, and interpret VWP and pumping data for depressurization.
- Conduct routine TSF inspections and data validation in coordination with the Engineer of Record/RPTE; support compliance with GISTM guidance and dam safety reviews.
- Scope, budget, and supervise geotechnical drilling, logging/sampling, laboratory testing, instrumentation installation, and ground‑support trials; manage contractors and service agreements for monitoring systems.
- Maintain and archive project records, drawings, and change‑management documentation.
Recommend operating and capital budgets; track spend and asset condition.
- Provide training and mentoring to operators and junior engineers; deliver toolbox talks and participate in continuous improvement and technology trials.
Other duties as assigned.
