FP&A Lead

Overview

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.

We are hiring a FP&A Lead to build and own the financial planning, forecasting, and performance intelligence that powers day-to-day and long-term decision-making across Mariana. This is a hands-on, builder role
. You will work directly with business and asset leaders to track spend, analyze performance versus plan, explain variances, and help teams course-correct in real time. A key part of this role is helping design and build systems—within Mariana

OS and related data pipelines—that deliver near–real-time financial insight rather than relying solely on month-end closes.

This role is ideal for someone who is comfortable rolling up their sleeves: building models in Excel, working with APIs and data tools, visiting assets, and solving messy problems firsthand.

• Own company-wide FP&A across assets and the parent company
• Build and maintain budgets, forecasts, and long-range financial models
• Track purchase order commitments and actual spend vs. budget
• Analyze and explain variances with business and budget owners
• Partner with leaders to plan corrective actions and optimize spend
• Develop dashboards and tools that provide near–real-time financial visibility
• Work closely with Accounting to reconcile operational data with financials
• Support long-term planning and capital-raising efforts with clear financial insight
• Translate complex financial data into actionable business intelligence

• 5-10 years of experience in FP&A, finance, investment banking, consulting, or a closely related role
• Strong hands-on modeling skills (Excel required)
• Experience working directly with operators or asset-level leaders
• Background in natural resources, energy, infrastructure, or other capital-intensive businesses preferred
• Comfort building scrappy tools (models, lightweight apps, data pipelines) to solve problems
• Ability to operate independently without a large team or support structure
• Strong business judgment and communication skills
• Willingness to be in the office most days and visit assets as needed to work with day-to-day teams

At Mariana Minerals, you’ll be part of a mission-driven team reshaping the way critical minerals are sourced and supplied globally. You’ll have the autonomy to make big decisions, the tools to innovate, and a culture that values ownership, smart automation, and collaboration.

Extreme Ownership — We take full responsibility for outcomes, relentlessly driving toward solutions.

Join us as we build the future of responsible mineral sourcing and supply.
