About The Position

Wafer is building AI systems that automatically optimize inference workloads across silicon. The company serves trillions of tokens each month for mission-critical workloads at fast-growing AI startups. The Head of Finance will own Wafer’s financial operations, including billing, revenue and compute accounting, planning, and fundraising support. Working directly with the founders, this person will build the finance function while also executing its day-to-day work.

The role owns the books, monthly close, and audit, and is responsible for timely, accurate financials. It oversees billing and revenue accounting for usage-based and committed contracts, ensuring token usage is billed correctly and reconciles with reported results. It also builds the financial model and planning process across revenue, product gross margin, compute spending, and hiring; manages compute economics with the team responsible for purchasing capacity; and leads finance work for fundraising and investor reporting. Additional ownership includes tax, payroll, equity administration, insurance, vendor contracts, and scalable systems and controls. The position is onsite in San Francisco five days a week, with substantial autonomy and broad ownership.
