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. Join us as we build the future of mining and minerals refining.

Mariana is hiring a Lead Project Engineer to join our team in Moab, UT. In this pivotal role, you will engineer and deploy first of a kind mining and refining technologies and work across Mariana’s process development, software, plant engineering, project execution, and operations teams to drive the planning, execution, and delivery of complex, cross-functional projects that are central to our mission.

This role is not for the faint of heart, so do not apply unless you are excited about extreme ownership of ambiguous, cross-disciplinary problems, passionate about solving the looming critical minerals crisis, and want to work insanely hard.
