Product Finance Manager

What you'll do

As Finance Manager, Product Finance, reporting to the Head of Finance, you'll own finance for Giga's manufacturing operations, procurement, and go-to-market functions. You'll build BOM-level cost visibility down to the component and sub-assembly, forecast COGS as production scales, and give leadership a real-time view into margin by product line. You will also own the critical pricing and lead times for our data center development. This is a build role for someone who wants deep ownership over both sides of the P&L that determine whether Giga's unit economics work at scale.

Where you'll work

We are an in-office culture — velocity matters when you're building physical infrastructure, and the best decisions happen in the room. This role is ideally based in one of our offices in Houston, San Francisco, or LA/Long Beach. That said, we will make exceptions for truly exceptional talent if you live outside one of our hubs. If you're the right person for this role, we'll have a conversation about what works.
