Responsibilities

• Corporate Development raises the capital and closes the transactions that take Mariana's projects from development to operation. The team sits at the intersection of corporate finance, project finance, and M&A, and works directly with the CEO, CFO, and commercial leadership.
• equity raises, project-level equity, project finance debt, export credit agency and government-backed financing, venture and corporate debt.
• offtake agreements, prepayments, working capital and inventory financing with strategics and commodity trading houses.
• acquisitions, joint ventures, and strategic partnerships across lithium, copper, and adjacent minerals.
• materials, process management, and ongoing engagement with existing and prospective investors and lenders.
• We are hiring an Associate and a Manager. Both roles report to the Director of Corporate Development, are based in Houston, and will help build how the function itself runs on MarianaOS.

Associate, Corporate Development

• The Associate is the analytical engine of the team: building the models, materials, and diligence work that underpin every financing and transaction. You will have direct exposure to senior management and counterparties from day one, on live deals.
• Build and maintain financial models: project-level DCFs, life-of-mine models, financing structures, returns and sensitivity analysis, and corporate funding plans.
• Prepare investor presentations, lender materials, board materials, and internal decision memos.
• Run diligence workstreams: manage data rooms, coordinate third-party advisors (technical, legal, environmental, market), and track and respond to diligence requests.
• Analyze and benchmark transaction terms, including offtake, prepayment, and debt term sheets, and support the team in negotiations.
• Track comparable transactions and peer companies to inform valuation and strategy.
• Help build the function's tooling on MarianaOS: models, data pipelines, and workflows that make the team faster.

Requirements

• 2–4+ years in investment banking, private equity, or corporate development.
• Strong financial modeling from a blank page; comfortable building and auditing complex, integrated models.
• Clear, concise written communication and polished presentation materials.
• High ownership and attention to detail; able to run multiple workstreams in parallel.
• Bachelor's degree in finance, economics, engineering, or a related field.

Preferred

• Exposure to project finance, natural resources, or infrastructure transactions.
• Familiarity with mining concepts (reserves and resources, technical reports, commodity pricing).
• Comfort with Python, SQL, or other tools beyond Excel.
