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.

Support PO conversion, approvals, and procurement system execution.
Manage Contracts & Commercial Risk
Draft, review, and negotiate NDAs, MSAs, construction work orders, and equipment purchases.
Manage change orders and commercial amendments in coordination with project teams.
Ensure documentation is structured, defensible, and audit-ready.
Drive Cost & Value
Analyze spend and identify savings or value-creation opportunities.
Support competition in the supplier market.
Conduct commercial risk assessments to reduce schedule and supply chain exposure.
Build Better Systems
Help design scalable procurement processes as the company grows.
Improve cycle times and reduce friction in sourcing and approvals.
Contribute to building a disciplined, data-driven procurement function from the ground up.
