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.

We’re 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.
