- Lead E&I crews, electricians, instrumentation technicians, contractors, and other field personnel.
- Plan and coordinate work assignments based on production requirements, maintenance priorities, and available resources.
- Ensure all work is performed safely and in compliance with applicable mine safety regulations, electrical codes, company policies, and site procedures.
- Conduct and participate in pre-shift meetings, toolbox talks, job hazard analyses, and safety inspections.
- Ensure proper lockout/tagout, isolation, grounding, and electrical safe-work practices are followed.
- Troubleshoot, diagnose, and oversee repairs to underground electrical distribution systems, motors, controls, PLCs, instrumentation, communication systems, and related equipment.
- Supervise installation, commissioning, testing, and maintenance of electrical and instrumentation systems.
- Support installation and maintenance of underground power distribution, substations, transformers, switchgear, MCCs, motor starters, VFDs, lighting, pumps, ventilation systems, and other mine infrastructure.
- Oversee instrumentation and control systems, including sensors, transmitters, process controls, monitoring systems, and PLC-based equipment.
- Review electrical drawings, schematics, one-lines, control diagrams, and equipment documentation to support field activities.
- Coordinate with engineering and maintenance personnel on equipment modifications, system upgrades, and capital projects.
- Monitor work quality and verify installations and repairs meet design specifications and applicable standards.
- Manage contractors and subcontractors performing E&I work underground.
- Maintain accurate maintenance records, inspection reports, work orders, and documentation.
- Assist with planning manpower, materials, tools, equipment, and spare parts required for scheduled and unscheduled work.
- Identify recurring equipment failures and recommend improvements to increase reliability and reduce downtime.
- Participate in root-cause analysis and continuous-improvement initiatives.
- Ensure personnel are properly trained, qualified, and authorized to perform assigned electrical and instrumentation work.
- Coach, mentor, and develop E&I personnel while promoting a strong safety and accountability culture.
- Respond to underground electrical and instrumentation emergencies and production-critical equipment failures as required.
- Perform other duties as assigned by the Maintenance Manager, Maintenance Superintendent, or Mine Operations leadership.
The above responsibilities are representative and may not include all assigned duties.
Education and Experience- High school diploma or GED required.
- Technical diploma, associate degree, or other post-secondary education in Electrical Technology, Instrumentation & Controls, Industrial Electrical, Electronics, or a related discipline preferred.
- Journeyman Electrician license or equivalent recognized electrical qualification strongly preferred; requirements may vary based on jurisdiction.
- 5+ years of progressive electrical and/or instrumentation experience, preferably in an underground mining, heavy industrial, or mineral processing environment.
- 2+ years of supervisory or lead experience overseeing electrical, instrumentation, or maintenance crews preferred.
- Demonstrated experience working with underground mining electrical systems and equipment.
- Strong working knowledge of industrial electrical systems, motor controls, MCCs, VFDs, transformers, switchgear, PLCs, instrumentation, and control systems.
- Experience troubleshooting electrical and control-system faults using electrical drawings, schematics, test equipment, and diagnostic tools.
- Working knowledge of applicable electrical codes, mining regulations, and safe electrical work practices.
- Experience with preventive and predictive maintenance programs is preferred.
- Experience with computerized maintenance management systems (CMMS) preferred.
- Ability to read and interpret electrical one-lines, wiring diagrams, control schematics, instrumentation drawings, and equipment manuals.
- Demonstrated ability to lead crews in a demanding underground work environment.
