About the Job As Panthalassa moves from pilot systems toward repeatable production, large-scale facilities, and commercial deployments, we need financial systems, models, and decision tools that can keep pace with unlocking planetary-scale energy. As FP&A Manager, you will help build and maintain the analytical infrastructure that connects operations, accounting, strategy, and finance. Your work will support planning, budgeting, project development, manufacturing scale-up, capital strategy, and the financial decisions that shape how we grow. This is a hands-on corporate finance role for someone who can build rigorous models from first principles, pressure-test assumptions, and turn complex analysis into clear recommendations. Responsibilities Build and maintain corporate finance, FP&A, and liquidity models that support budgeting, forecasting, scenario planning, runway analysis, and capital allocation decisions. Develop financial models for project development, manufacturing scale-up, structured financing, tax credits, asset-level economics, and capital strategy. Partner with operations, engineering, manufacturing, procurement, accounting, and strategy teams to translate build plans, vendor quotes, BOMs, headcount plans, facilities assumptions, and deployment schedules into financial forecasts. Create durable planning tools that give leadership visibility into cash needs, cost drivers, capital efficiency, and key tradeoffs across build, buy, finance, and deployment decisions. Support budgets, rolling forecasts, variance analysis, board materials, investor updates, lender materials, and capital raise processes with clean, decision-ready analysis. Work closely with accounting to reconcile forecasts to actuals, improve data quality, and keep financial models grounded in reliable operating and accounting information. Identify the highest-leverage gaps in Panthalassa’s financial operating system and build practical mechanisms to close them. About You You are analytical, curious, and comfortable with ambiguity. You can build a model from a blank sheet, explain the logic behind it, and defend the conclusions under senior-level scrutiny.

You want to understand the underlying physics, operations, tax rules, financing terms, and commercial constraints well enough to build models that reflect reality. You communicate clearly with both finance and non-finance teams. You can sit with an operations lead, understand what is changing on the floor, and translate it into a forecast. You can sit with leadership, explain what changed, and separate the signal from the noise. You bring rigor without creating unnecessary process. Required Qualifications 3-6 years of experience in investment banking, structured finance, private equity, private credit, strategic finance, corporate finance, or FP&A in a high-growth, capital-intensive company. Advanced Excel modeling skills, including three-statement modeling, cash forecasting, scenario analysis, debt schedules, capitalization structures, and returns analysis. Experience building models used for real decisions, not just reporting packages. Strong understanding of corporate finance, capital structure, working capital, liquidi
