The posting

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 Mariana is hiring a Commercial Manager, Energy & Utilities to own electricity, water, and natural gas agreements across our operating sites and sites in development. This is a commercial role — you will take load requirements and operating plans from engineering and operations and translate them into negotiated service agreements, benchmarked rates, and contract structures that work for Mariana over the long term.

You will cover both traditional utility contracting and alternative energy options including on-site generation, storage, and renewable supply. You will assess providers on credit and reliability, work with local governments and utilities on permitting and incentives, and maintain a clear picture of utilities spend and supply risk across the portfolio.

What You'll Do

- Develop utilities contracting strategy for each site, from initial connection through steady-state operations

- Negotiate power, water, and natural gas agreements covering rates, terms, and renewal structures; benchmark pricing against market and comparable facilities

- Assess utility and service providers on credit, financial stability, and delivery reliability

- Convert site load forecasts and operating plan changes provided by engineering and operations into utility capacity and contract requirements

- Evaluate renewable energy options including on-site generation (including solar and geothermal energy), battery storage, and power purchase agreements, covering cost, reliability, and operational impact

- In coordination with our Government Affairs function, work with utilities, local governments, and relevant community stakeholders to advance utility access and generation strategies for sites, including economic incentives, permitting, and related regulatory pathways

- Track utilities contracts across the portfolio, monitoring expiration dates, renewal windows, and supply risk; report on utilities spend and contract status to leadership

Desired Qualifications

- 5+ years negotiating utility, energy, or industrial infrastructure service contracts, ideally from the customer side

- Working knowledge of power markets, rate structures, and interconnection processes

- Strong credit and counterparty risk judgment

- Proven ability to make and defend commercial decisions independently, with limited day-to-day direction

- Hands-on experience with at least one renewable procurement structure such as a PPA or green tariff, and a working understanding of the others

- Familiarity with on-site generation and battery storage (solar, microgrids), including project economics and incentives

- Ability to work with engineers to assess technical feasibility, reliability tradeoffs, and payback

- Experience with international utility and energy contracting is 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!

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
