Head of Finance

Head of Finance

At Wafer, we are building AI systems that automatically optimize inference workloads across silicon. Wafer is well funded and serves trillions of tokens a month for mission-critical workloads at fast-growing AI startups.

We're looking for a Head of Finance to own Wafer's numbers: how we bill, how we account for revenue and compute, how we plan and how we raise. You'll work directly with the founders and build the finance function while doing the work yourself.

What you'll do

Own the books, the monthly close and the audit. Get to accurate financials quickly, every month.

Own billing and revenue accounting for usage-based and committed contracts. Make sure every token we serve is billed correctly and reconciles to what we report.

Build the financial model and planning process: revenue, gross margin by product, compute spend and hiring.

Manage compute economics with the team that buys it: GPU contracts, capacity commitments, financing and cash.

Run the finance side of fundraising and investor reporting: data room, diligence and board materials.

Own tax, payroll, equity administration, insurance and vendor contracts, with outside partners where it makes sense.

Build the systems and controls that let the company scale without slowing down.

What we look for

You have run finance at a high-growth startup, or held a strong finance role at one after banking, investing or audit. You have owned a close and a model, not just reviewed them.

You have worked with usage-based or infrastructure revenue: metered billing, committed contracts and revenue recognition.

You are comfortable with a large, variable cost base. Experience with compute, cloud or hardware commitments is a plus.

You have supported a fundraise or diligence process and can defend every number in the data room.

You are technical enough to work from raw data. You can query usage data or build the reconciliation yourself rather than waiting for a report.

You work without a spec. You can see what the company will need in a year and build it now.

How we work

On-site in San Francisco, five days a week. Small team with massive surface area and ownership. You operate with complete autonomy of how to solve problems.

You will build the finance function while doing the work yourself. Your success is measured by how well the company understands and controls its numbers, and how fast it can act on them.
