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.
Mariana Minerals is building modern mining and processing operations, and we’re looking for people who want to keep them running and grow with us. This is open to students who have finished a technical program or are about to, and to people with industrial or mechanical experience who are new to mining.
Maintenance techs are the backbone of any mine site. It’s hands-on work with real equipment, new problems to solve every day, and skills that stay in demand across industries. Join early and you’ll learn from experienced techs, see how a modern operation comes together, and build a career with a company that’s just getting started.
Program details are still coming together, but we’re connecting early with people who want to help build this team.
What You Could Learn
Mechanical maintenance: pumps, conveyors, crushers, hydraulics, and heavy equipment
Electrical maintenance: motors, controls, VFDs, and instrumentation
How technicians support a mine and processing plant from start to finish, through both preventive maintenance and real-time troubleshooting when equipment goes down
Mine site safety, including MSHA training, lockout/tagout, arc flash (NFPA 70E), rigging, confined space, and working at heights
Who Should Apply
Students in electrical, mechanical, or industrial maintenance programs, and recent trade school or technical program grads
Already working as a welder, fabricator, heavy equipment operator, driller, or facilities tech? If you have a stable work history and want to build your maintenance skills, this is a great next step.
Experienced mechanics, electricians, or military-trained techs looking to move into mining
Reliable, safety-minded team players who are coachable and ready to learn
Hands-on problem solvers who like figuring out why things break and how to fix them
Comfortable with hand and power tools (experience helps, but isn’t required for students)
Working Environment & Physical Requirements
This is a mine site, and safety comes first every day. You’ll work outdoors and in industrial settings with exposure to dust, loud noise, and all kinds of weather, from summer heat to winter cold. Required PPE includes a hard hat, steel-toe boots, safety glasses, high-visibility clothing, and hearing protection, with respirators and fall protection when the job calls for it. All apprentices complete MSHA safety training and are expected to follow site safety rules at all times. The work can include lifting up to 50 lbs, climbing, working at heights, and entering confined spaces.
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!
