## 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 commercially strong, hands-on Procurement Manager, Construction to lead procurement of construction and installation contracts for our capital projects, including site work, civil, structural, mechanical, piping, and E&I packages.

This is a senior individual contributor role. You will own your category end-to-end, from strategy and bid packages through award, execution, and closeout, leading cross-functional teams without direct reports. Your decisions will directly shape project schedule, capital efficiency, and commercial risk.

  

**What You’ll Do**

**Lead Construction Procurement**

-   Develop contracting strategies for construction packages, selecting contract type (lump sum, unit price, T&M, cost reimbursable) and package splits based on scope maturity, schedule, and risk.
    

-   Prepare and run competitive bid packages, including contractor prequalification, pre-bid meetings, and site walks.
    

-   Lead bid leveling, clarifications, and negotiations, and make award recommendations through the company’s approval thresholds.
    

-   Set up MSAs and work orders for repeat and phased construction work.
    

**Lead Cross-Functional Teams**

-   Lead package teams of construction management, engineering, project controls, HSE, finance, and legal to align on scope, schedule, and commercial strategy.
    

-   Run technical and commercial evaluations with stakeholders and drive the group to a clear, defensible award decision.
    

-   Mentor project teams and procurement colleagues on negotiation, commercial risk allocation, and contract administration.
    

**Own Contracts & Change Management**

-   Negotiate construction terms, including risk allocation, insurance and bonding, retention, liquidated damages, payment terms, and warranty.
    

-   Manage change orders, claims, and disputes with field and project controls teams, verifying pricing against contract rates and markups.
    

-   Oversee progress billing, lien waivers, and closeout documentation so records are complete, defensible, and audit-ready.
    

**Drive Cost & Value**

-   Build and maintain a qualified contractor base in our project regions, assessing safety performance, capacity, and financial strength.
    

-   Benchmark labor rates, unit prices, and markups, and use historical data to inform estimates and negotiations.
    

-   Identify and mitigate labor availability, schedule, and counterparty risk across the project portfolio.
    

-   Track and report savings, cycle times, and contractor performance to leadership.
    

**Build Better Systems**

-   Own the design and continuous improvement of construction contracting templates, processes, and approval workflows.
    

-   Partner with software teams to automate sourcing, bid leveling, and contract administration.
    

-   Establish the metrics, controls, and reporting that make procurement a disciplined, data-driven function.
    

  

**Desired Qualifications**

-   10+ years of procurement or contracts experience in:
    

-   Construction contracting for industrial, mining, or process facilities
    

-   Civil, structural, mechanical, piping, or E&I packages
    

-   Capital projects in owner, EPC, or EPCM environments
    

-   Proven ability to lead cross-functional teams without direct authority, including serving as the procurement lead on major capital projects.
    

-   Track record leading competitive bids and negotiations for multimillion-dollar construction contracts.
    

-   Deep understanding of construction contract types and terms, including insurance, bonding, retention, and liquidated damages.
    

-   Hands-on experience with field change management, progress billing, and contract closeout.
    

-   Proficient with ERP/procurement systems and structured documentation; comfortable with data and eager to automate.
    

-   Strong communicator with executives, project leaders, and suppliers.
    

-   Bachelor’s degree in construction management, engineering, business, or a related field; CPSM, CPM, or similar certification a plus.
    

### **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!**
