About the Role

We’re looking for a Director of Finance to help shape Spellbook’s next stage of growth. You will work closely with our VP of Finance, executive team, and leaders across the company to translate strategy into financial plans, guide our most important investment decisions, and create a clear view of business performance.

This role sits at the intersection of finance, strategy, and company execution. As the company scales, you will build the capabilities, processes, and operating cadence to develop insight into the drivers of our business and bring analytical rigor to decisions across growth, product investment, organizational capacity, and capital allocation.

Responsibilities

• Build investment cases for major strategic bets, new segments, market entry, GTM and product investments, and lead post-investment reviews to assess expected versus realized returns.
• Own the framework for allocating spend and headcount across GTM, R&D, and G&A, including the mechanisms and decision criteria for reallocating resources as priorities change.
• Own the annual planning, quarterly forecasting, and rolling outlook processes, establishing clear inputs, owners, timelines, and accountability for forecast accuracy.
• Make unit economics legible to non-finance leaders, including gross margin and model/inference costs, cost-to-serve, CAC payback, customer profitability, and NRR/GRR.
• Partner with GTM and Product on pricing and packaging as the model evolves, including usage-based components.
• Work with the finance team to shape our systems roadmap: CRM, billing, ERP, expense, and reporting.
• Partner with the VP Finance and executive team on board and investor materials, translating company performance and strategic decisions into a clear financial narrative.
• Build the capabilities, processes, and operating cadence required for a high-performing strategic finance function.
