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.
