Underground Construction Technician

Underground Construction Technician

Join a safety-led, people-first team that invests in your growth, values your ideas, and creates real pathways for long-term career progression. Gain multi-trade, hands-on experience across mechanical, piping, structural, and civil construction in a technically advanced underground environment. Be part of a once-in-a-generation underground project that will help shape the future of U.S. copper production right here near Superior, Arizona.

About the role

Build your career underground with one of Arizona's most advanced mining projects. As an Underground Construction Technician, you will play a hands-on role installing the critical infrastructure that keeps operations moving safely and efficiently. This is an opportunity to expand your skills across mechanical, piping, structural, and civil work, all while working alongside experienced professionals who are invested in your development and long-term growth in the Copper Triangle.

A strong shift starts with clear direction and well-coordinated crews. Materials are staged and ready, communication across teams is aligned, and installations move forward without delays. You and your team install piping and ventilation systems efficiently, complete equipment alignment and testing with confidence, and close out the shift knowing your work met quality standards and supports safe, reliable operations.

Not every shift goes to plan. At times, you may encounter incomplete deliveries, tight underground conditions, or discrepancies between drawings and field reality. You adapt by coordinating closely with engineering, re-sequencing tasks, and maintaining a strong focus on safety. Even when progress requires extra effort, your ability to communicate, solve problems and stay flexible ensures the work continues moving forward without compromising standards.

You will be guided by an experienced Underground Operations Supervisor and supported by a collaborative team of construction, maintenance, engineering, and contractor partners who work together to help you succeed and grow, including in the following responsibilities:

Construction & Installation

• Prioritize safety every shift by following underground safety standards, completing pre-start checks, and actively identifying and addressing hazards

• Assemble and install ventilation systems including fans, ducting, and regulators
• Build and install structural steel, platforms, and equipment supports to specification
• Support concrete, civil, and grouting activities including formwork and equipment setting
• Perform testing and commissioning activities such as hydrotesting, flushing, and functional verification
• Safely operate tools, rigging systems, and light equipment while supporting underground material movement

Project Support

• Support a safe and coordinated work environment by collaborating daily with engineering, maintenance, and contractor teams
• Read and interpret engineering drawings, P&IDs, fabrication drawings, and isometrics with confidence
• Verify field conditions and communicate discrepancies to maintain construction accuracy
• Coordinate underground material staging and deliveries to keep work progressing efficiently
• Track daily progress and provide clear updates to supervisors and team members
• Maintain accurate construction documentation including redlines and as-built markups
• Contribute to project planning, sequencing, and scheduling discussions
• Work collaboratively across teams to meet project timelines and quality expectations
