The posting

ABOUT MARIANA MINERALS

Mariana Minerals is a software-first, vertically integrated minerals company on a mission to supply the critical minerals powering modern energy, AI, and defense technologies. We’re reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.

Through its Copper One platform, Mariana Minerals owns and operates Lisbon Valley Mining Company, a producing open-pit copper mine in southeastern Utah running 24/7.

As a Process Maintenance Technician, you'll maintain and repair everything that's "nailed to the ground": pumps, compressors, boilers, piping, valves, and the buildings that keep the operation running. The ideal candidate is strong in at least one area, such as pumps, welding, or troubleshooting, and is ready to cross-train in the rest.

RESPONSIBILITIES

- Diagnose, install, and repair fixed plant equipment, including pumps, compressors, boilers, fans, motors, gearboxes, piping, valves, and automated valves, identifying root causes.

- Maintain site buildings and infrastructure, including truck shops, admin buildings, and plumbing systems, along with portable equipment such as mobile air compressors and pumps.

- Perform welding and fabrication for pipe, frames, handrails, grating, and structural repairs.

- Perform equipment rebuilds, component replacements, lubrication, inspections, oil sampling, and other preventive and condition-based maintenance.

- Perform basic electrical troubleshooting and repair on motors, starters, and controls, and work alongside electricians to rack out, unwire, install, and troubleshoot process equipment.

- Safely operate forklifts, overhead cranes, boom trucks, and other material-handling equipment.

- Document inspections, repairs, and parts in work orders and the CMMS.

- Follow MSHA regulations, lockout/tagout procedures, PPE requirements, and company SOPs.

QUALIFICATIONS

- Maintenance experience in fixed plant, mining, industrial, or heavy manufacturing environments.

- Strong hands-on skills in at least one area: pumps, welding and fabrication (MIG, stick, cutting), or mechanical troubleshooting.

- Working knowledge of pumps, motors, gearboxes, piping systems, and mechanical drive systems.

- Basic electrical knowledge, including reading wiring diagrams, using a multimeter, and troubleshooting motors and controls. Industrial electrical experience is a plus.

- Ability to read and interpret service manuals, parts manuals, schematics, and technical documentation.

- Ability to work safely in an active mine environment and perform physically demanding tasks.

- Experience using computerized maintenance management systems (CMMS).

- Strong communication skills and ability to work effectively with operators, electricians, and support teams.

WORKING ENVIRONMENT AND SCHEDULE

- Schedule: 7 days on / 7 days off, 12-hour shifts.

- Housing & Relocation: Housing and relocation assistance options are available.

- Able to walk rough terrain, climb, and lift 50+ lbs in all weather conditions.

- Exposure to dust, fumes, and chemicals (including sulfuric acid); full PPE required.

OUR CULTURE IS BUILT ON FOUR PRINCIPLES:

Everyone Gets Home Safe. We never put speed or cost ahead of people.

Extreme Ownership. We take full responsibility for outcomes, relentlessly driving toward solutions.

Engineer Out Requirements, then Automate. We simplify, optimize, and then automate for scale.

Share Your Legos. We collaborate openly, share knowledge, and empower each other to build bigger, better solutions.

Join us as we build the future of responsible mineral sourcing and supply!

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
