## 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 Corporate Development team**
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.
The team's work spans:
• **Corporate and project financing:** equity raises, project-level equity, project finance debt, export credit agency and government-backed financing, venture and corporate debt.
• **Structured commercial transactions:** offtake agreements, prepayments, working capital and inventory financing with strategics and commodity trading houses.
• **M&A and partnerships:** acquisitions, joint ventures, and strategic partnerships across lithium, copper, and adjacent minerals.
• **Investor relations:** 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.
**Manager, Corporate Development**
The Manager leads transaction workstreams end to end: owning the process, the counterparties, and the analysis behind them. You will negotiate directly, manage advisors, and help shape how Mariana finances its projects and pursues growth.
**What you'll do**
• Lead individual financing and M&A workstreams from origination through close, including process design, timeline, and counterparty management.
• Negotiate commercial and financing terms directly with investors, lenders, strategics, and trading houses, working alongside legal and commercial teams.
• Own the financial models and investment cases behind each transaction, and review and direct Associate's work.
• Structure transactions across the capital stack: project equity, project finance debt, ECA and government-backed financing, prepayments, and offtake-linked structures.
• Manage third-party diligence and advisors, and synthesize findings into clear recommendations for management and the board.
• Build and maintain relationships with investors, lenders, and strategic partners.
• Help design and build the corp dev function on MarianaOS, and mentor junior team members.
**What we're looking for**
• 4–7+ years in investment banking, private equity, or corporate development, with experience leading workstreams on closed transactions.
• Expert financial modeling and the judgment to know which assumptions drive value.
• Demonstrated ability to manage counterparties and negotiate terms.
• Executive presence and clear written and verbal communication with senior stakeholders.
• Comfort with ambiguity and building process where none exists.
• Bachelor's degree required; MBA or CFA a plus.
**Nice to have**
• Project finance experience in mining, energy, power, or infrastructure.
• Exposure to commodity offtake, prepayment, or trade finance structures.
• Experience working with export credit agencies, development finance institutions, or government loan programs.
**Preferred Location:** Houston, TX (in office). **Alternative Location:** San Francisco, CA (in office). **Target start:** early 2027.
