AP/ AR Specialist

As AP/AR Specialist on Giga’s Finance team, you will be the financial backbone ensuring money moves accurately and on time — both in and out. You’ll own the full accounts payable and receivable cycle in a high-velocity manufacturing and distribution environment where precision directly impacts operations. This isn’t a back-office processing role; you’ll work closely with procurement, operations, and customer teams to keep the business running without friction. Your work will be visible, your impact immediate, and your ability to bring order to complexity will directly support Giga’s growth. If you thrive on solving problems and making a tangible impact on the financials of a fast-growing company, this is your role.

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 our San Francisco, Long Beach, or Houston offices, with full-time onsite expectations outside of bi-weekly WFH Fridays.

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.
