More about this role
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 a core commissioning team of talented, versatile engineers who know how to take a plant from mechanical completion to running. As a Commissioning Engineer, you’ll own electrical and mechanical commissioning scopes: energizing power systems, bringing up equipment and utilities, and getting new systems online safely.
You’ll work alongside local commissioning teams, own your commissioning assignments, and make sure we’re building and using our systems throughout commissioning.
Your first year will likely be focused on Copper One, our operating copper mine and refinery in Utah, or Lithium One, our new lithium facility in Texas. After that, you’ll go wherever we’re bringing new capacity online, anywhere in the world. Between commissioning pushes, you’ll support design teams and projects at other sites. There’s always something being built.
