About The Position

We are hiring a Drill & Blast Engineer to design, execute, and optimize drilling and blasting operations at our surface copper site in La Sal, UT. In this role, you will lead blast design, oversee drilling programs, and partner closely with mine operations to deliver safe, efficient, and cost effective fragmentation that supports high performance heap leach and excavation workflows. You’ll work hands on at the mine site, integrating advanced design tools, data-driven reconciliation, and continuous improvement to push the boundaries of modern blasting performance—while upholding the highest standards of safety and regulatory compliance.

Requirements

  • Bachelor’s degree in Mining Engineering or a related field.
  • 5+ years of experience in surface mine drill & blast engineering.
  • Proficiency in blast design software (e.g., ShotPlus, JKSblast).
  • Strong understanding of MSHA and ATF regulations.
  • Experience with bulk ANFO and emulsion delivery systems.
  • Excellent communication skills and ability to work cross‑functionally with operators, engineers, and contractors.

Nice To Haves

  • Background in copper or heap leach operations (preferred).

Responsibilities

  • Develop and refine blast patterns and charge designs tailored to specific geotechnical domains across ore and waste.
  • Utilize ANFO, emulsions, bulk delivery systems, and timing systems (Nonel/electronic) to achieve optimal fragmentation and vibration control.
  • Apply advanced blast modeling tools for fragmentation, timing, and vibration analysis.
  • Lead KPI reconciliation, including powder factor, cost/ton, fragmentation outcomes, dilution, and elevation control, to improve blast performance over time.
  • Plan and coordinate drilling patterns and schedules aligned with short and long term mine plans.
  • Oversee drill contractors to ensure compliance with safety standards, hole specifications, production rates, and QA/QC.
  • Maintain rigorous focus on pit wall stability through careful design and geotechnical collaboration.
  • Champion a safety-first culture in all blasting and explosives-handling activities.
  • Ensure all operations exceed MSHA, ATF, and state regulatory requirements.
  • Maintain accurate explosives inventory, blast logs, and compliance documentation.
  • Conduct pre blast assessments and post blast evaluations to verify safety and performance.
  • Partner with blasting crews to ensure designs are executed accurately in the field.
  • Analyze explosive consumption, initiation systems, and operational parameters to optimize total blasting cost.
  • Identify, evaluate, and implement new technologies or methodologies that enhance efficiency and reduce operating cost.
