Responsibilities

We are seeking an experienced Vice President of Finance to lead and scale Mariana Minerals' existing Accounting and FP&A team as we grow from two capital-intensive flagship projects today toward a broader portfolio of commercial mining and mineral-processing operations. Reporting to the Co-Founder & Chief Financial Officer, this role owns the finance organization's execution end to end — technical accounting, close, audit, and controls on one side; budgeting, forecasting, and cross-functional business partnering on the other.
The ideal candidate combines deep technical accounting expertise with strong strategic and people leadership, and has scaled a finance function before at a capital-intensive, high-growth company. As Mariana continues to grow, this role will play a key part in strengthening internal controls, building financial infrastructure, and preparing the company for its next stage of growth.
This role will work closely with the CEO, CFO, project leadership, and the board, and will lead Mariana's existing Accounting and FP&A staff across multiple operating locations.
FP&A & Strategic Finance
Lead company-wide budgeting, forecasting, and long-range planning across corporate and project-level P&Ls – particularly in the form of development and management of Mariana’s internally-developed FP&A tools and BizOs software platform.
Partner directly with the CEO, CFO, and project leadership on capital allocation, unit economics, and project-level financial modeling for Lithium One, Copper One, and future sites.
Own board and investor reporting, including monthly and quarterly board packages, investor updates, and ad hoc requests from Mariana's investor base.
Build the financial infrastructure, reporting cadence, and KPIs needed to support Mariana's plan to stand up ten commercial projects over the next decade.
Accounting & Controllership
In conjunction with Mariana’s Controller, own the monthly, quarterly, and annual close process, ensuring accurate, timely, and audit-ready financials across all entities and projects.
Serve as the primary point of contact for external auditors and tax advisors; manage the annual audit process end to end.
Set and maintain technical accounting policy, including capitalized project costs, inventory and commodity accounting, revenue recognition, and foreign currency, as operations scale.
