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.
Role Overview
Mariana Minerals is looking for a hands-on, commercially strong Procurement Specialist to support capital project delivery across construction 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 construction packages
• 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, and construction work orders
• 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 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
What You'll Bring
• 5–7+ years of procurement experience in heavy industry, capital construction, infrastructure, or industrial projects
• Experience leading competitive sourcing processes for construction
• Strong contract negotiation skills
• Clear understanding of commercial risk allocation
• Proficient with ERP/procurement systems and structured documentation
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.
