Mariana Minerals is a software-first, vertically integrated minerals company supplying critical minerals for modern energy, AI, and defense technologies. The company is reimagining the minerals supply chain through deep industry expertise combined with advanced software, automation, and data-driven decision-making.
As Commercial Manager, Energy & Utilities, you will own electricity, water, and natural gas agreements across operating sites and sites in development. This is a commercial role where you translate load requirements and operating plans from engineering and operations into negotiated service agreements, benchmarked rates, and contract structures that serve Mariana's long-term interests.
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 visibility of utilities spend and supply risk across the portfolio.
Key responsibilities include:
- Developing utilities contracting strategy for each site from initial connection through steady-state operations
- Negotiating power, water, and natural gas agreements covering rates, terms, and renewal structures; benchmarking pricing against market and comparable facilities
- Assessing utility and service providers on credit, financial stability, and delivery reliability
- Converting site load forecasts and operating plan changes from engineering and operations into utility capacity and contract requirements
- Evaluating renewable energy options including on-site generation (solar, geothermal), battery storage, and power purchase agreements for cost, reliability, and operational impact
- Coordinating with Government Affairs to work with utilities, local governments, and community stakeholders on utility access and generation strategies, including economic incentives, permitting, and regulatory pathways
- Tracking utilities contracts across the portfolio, monitoring expiration dates, renewal windows, and supply risk; reporting on utilities spend and contract status to leadership
Requirements:
- 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 working understanding of 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
- International utility and energy contracting experience is a plus
