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 already have strong team of engineers, product managers and end users; what we don't have is someone whose full-time job is to sit with complexity and simplify it. We're hiring our first dedicated design hire to help bring MarianaOS to the next level. You'll work across teams to ensure that MarianaOS is intuitive, and human-centered on the surface while managing a tremendous amount of complexity underneath. This is not primarily a pixel-polish role; it's a role for someone who can take genuinely complicated, data-heavy workflows and make them feel obvious.

• Grow and own our design system, including coded components and not just Figma files, which
