Position Summary

We are hiring a Maintenance Mechanic for our new project team at our Moab site, formerly Lisbon Mines, to assemble and install equipment for new projects.

The ideal candidate is motivated by change and wants to be part of a growing company. The work varies week to week, from setting up equipment and supporting construction builds to helping controls projects come together. As one of the first members of a new project team, you'll often own a job from start to finish and build new skills along the way.

Responsibilities

• Assemble, install, and set up equipment for new and ongoing projects

• Support construction-type projects, from small builds to equipment installs

• Work with mechanical, hydraulic, and pneumatic systems as projects require

• Plan and carry out small projects independently, from materials to completion

• Partner with the project electrician and project engineer to bring projects online

• Troubleshoot and solve problems on the fly when things don't go to plan

• Keep work areas safe, organized, and compliant with site safety standards

Qualifications

• Mid-level experience as a maintenance mechanic, millwright, industrial mechanic, or similar

• Strong mechanical aptitude and a proven ability to assemble and install equipment

• Working knowledge across multiple areas, such as hydraulics, pneumatics, fabrication, or light electrical

• Comfort working independently on small projects with minimal supervision

• Ability to read mechanical drawings and schematics

• A willingness to take on work outside your comfort zone

• Mining or construction experience is welcome but not required; manufacturing and other industrial backgrounds are a great fit

Schedule

• Monday-Friday days

Working Environment & Physical Requirements

• Lift at least 50 lbs, with exposure to dust, noise, vibration and diesel

• Wear all required PPE (hard hat, steel toes, safety glasses, hi-vis, hearing protection, and a respirator when 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!
