Job Description
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.
The Role
We are looking for a hands-on, commercially strong Procurement Specialist to support capital project delivery across equipment, construction, and industrial services.
This role is not transactional purchasing. You will own defined procurement scopes end-to-end, from strategy through contract award and execution, and directly impact project schedule and capital efficiency.
What You’ll Do
Own Capital Procurement Workstreams
• Lead pre-award, award, and post-award contracting activities for capital equipment, construction packages, and industrial services.
• Develop and execute procurement strategies aligned with project schedules and critical path activities.
• Drive commercial negotiations focused on total cost, risk allocation, and delivery certainty.
• 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.
Desired Qualifications
• 2-5+ years of procurement experience in:
• Equipment purchasing,
• Heavy industry
• Capital construction
• Infrastructure or industrial projects
• Experience leading competitive sourcing processes for capital equipment or construction.
• Strong contract negotiation skills.
• Clear understanding of commercial risk allocation.
• Proficient with ERP/procurement systems and structured documentation.
Why Join Us?
At Mariana Minerals, you’ll be part of a mission-driven team reshaping the way critical minerals are sourced and supplied globally. You’ll have the autonomy to make big decisions, the tools to innovate, and a culture that values ownership, smart automation, and collaboration.
Our culture is built on three principles:
Extreme Ownership – We take full responsibility for outcomes, relentlessly driving toward solutions.
Engineer Out Requirements, then Automate – We simplify, optimize, and then automate for scale.
Share Your Legos – We collaborate openly, share knowledge, and empower each other to build bigger, better solutions.
Join us as we build the future of responsible mineral sourcing and supply.
