We’re reimagining the minerals supply chain by combining deep industry expertise with advanced software, automation, and data-driven decision-making.

### Sr. Construction Project Manager

### Role Overview

As a Sr. Construction Project Manager, you will play a central role in managing new facility construction, capacity expansions, and major infrastructure projects. You'll oversee contractors and project teams, manage budgets and timelines, and lead both in-field and office-based initiatives to deliver strategic capital projects. Your expertise will be vital to scaling operations safely, efficiently, and on budget.

### What You'll Do

**Project Ownership & Delivery:**

-   Take end-to-end ownership of assigned construction projects, ensuring stakeholder satisfaction and identifying cost efficiencies.
    
-   Direct project delivery from scope development and contractor procurement to construction, commissioning, and project close-out.
    
-   Lead project startup activities including forecasting, budgeting, and job cost tracking.
    
-   Manage major purchase orders with thorough pricing and scope reviews.
    
-   Ensure project compliance with Mariana Minerals standards and company policies.
    

**Procurement & Commercial Management:**

-   Evaluate bids, manage procurement, and negotiate for optimal project outcomes.
    
-   Review plans and technical diagrams to verify all required material and hardware are accounted for.
    
-   Handle change orders and claims, seeking favorable commercial resolution.
    
-   Prepare regular project reports on cost, schedule, risks, and overall quality.
    

**Contractor & Stakeholder Management:**

-   Maintain open communication with cross-functional teams (QC, QA, commissioning, facilities, operations).
    
-   Oversee contractor performance to ensure achievement of KPIs and deliverables.
    
-   Liaise with regulatory, permitting, and community stakeholders as needed.
    

**Systems & Automation:**

-   Collaborate with software engineering to advance project management tools and support ongoing automation.
    
-   Mentor junior team members and foster a culture of growth and efficiency.
    

**Health, Safety & Environment:**

-   Lead a "zero-harm" safety culture, conducting regular safety reviews and toolbox talks.
    
-   Ensure alignment with all HSE plans and regulatory requirements.
    
-   Monitor and manage environmental controls (dust, water, waste) during construction.
    

### What You'll Bring

-   Bachelor’s degree in Construction Management, Engineering, or related field; or equivalent experience.
    
-   8+ years in construction project management in industrial/mining/processing plants.
    
-   Demonstrated success delivering capital projects of $20M+ on schedule and within budget.
    
-   Skilled in Primavera P6, Microsoft Project, Office Suite, accounting, and estimating tools.
    
-   Proficient at reading and interpreting contracts, engineering documentation, and specifications.
    
-   Strong knowledge of construction practices, industry codes, procurement, electrical fundamentals, and accounting.
    
-   Excellent communication, judgment, and decision-making abilities in dynamic environments.
    
-   Willingness to travel up to 50% to project sites or offices.
    
-   Experience with EPC/EPCM delivery models highly desirable.
    

### **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!**
