## About the role

### 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 Sr. 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 four principles:

**Everyone Gets Home Safe. **We never put speed or cost ahead of people.

**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!**
