Head of Finance

Valar Atomics is building a next-generation nuclear energy company that is moving faster than any other nuclear company. As Head of Finance, you will be the financial architect of our business during a period where discipline, creativity, and speed matter equally. This is a builder role: you’ll craft our financial systems, forecasting models, controls, and internal rhythms from a true blank slate.

You’ll partner closely with our CEO, President, and functional leads to shape the company’s strategic trajectory across fundraising, commercial strategy, cost structure, and long-range planning.

We’re looking for a magical, full-stack finance leader: someone who can roll up their sleeves into the details, think like a CFO, and eventually build and scale a world-class finance organization.

• Build and own Valar’s financial operating model, including corporate model, scenario planning, and program-level economics.
• Develop the full finance infrastructure: FP&A, budgeting, forecasting, reporting, cost controls, and business partnering.
• Stand up core financial systems in partnership with Controller and Engineering / Manufacturing (ERP, procurement workflows, cash tracking, expense systems).
• Lead strategic financial planning for fundraising, investor storytelling, and board materials.
• Partner with engineering, product, and operations to model production cost curves, Cap Ex plans, vendor strategy, and revenue/pricing strategy.
• Build and lead a high-caliber finance team over time.

• A high-bandwidth operator who thrives in ambiguity and can zoom between 10,000 ft strategy and 10-ft details.
• Someone who can create structure out of chaos and build flexible systems where none exist.
• Experienced in high-growth companies, ideally climate/energy/hardware/defense-tech.
• A strategic partner who can pressure-test ideas, challenge assumptions, and drive decisions with data.
• A builder who loves ownership, accountability, and shipping finished work.
