AP/ AR Specialist

The Pace: We're building at a speed most companies talk about but never actually operate at. If you've been bored somewhere else, you won't be here. The Impact : Every person at Giga touches the work that matters. No layers, no waiting for approval chains. You'll see your fingerprints on what we ship. The Team: A team of operators defining the future of AI infrastructure. We recruit A-players from the most innovative companies in the world, and they choose Giga because the work here means more. The Moment : AI doesn't run without power, and that's us. Giga is the picks and shovels behind the AI revolution. This industry is about to explode, and you'll be in the room where it's already happening. What you’ll do 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. 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 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.

Prepare and run weekly check runs, ACH payments, and wire transfers; maintain vendor master data including W-9s, banking details, and contact information. Reconcile vendor statements and resolve invoice discrepancies in a timely manner; partner with procurement and warehouse teams on receiving and pricing disputes. Generate and distribute accurate customer invoices based on shipping documents and sales orders; monitor AR aging and proactively follow up on overdue balances. Post and apply customer payments (checks, ACH, credit cards) to appropriate invoices; process credit memos, returns, and adjustments in accordance with company policy. Prepare monthly AR aging reports with collection status commentary; support customer credit application reviews and credit limit evaluations. Perform monthly reconciliations of AP and AR sub-ledgers to the general ledger; support month-end and year-end close including journal entries and account analysis. Provide supporting documentation for internal and external audit requests; identify and drive process improvements within AP/AR workflows. Requirements 2+ years of hands‑on AP and/or AR experience in a manufacturing or distribution environment. Associate’s or Bachelor’s degree in Accounting, Finance, or Business Administration.

Excellent written and verbal communication skills for vendor and customer‑facing interactions. Experience with EDI invoicing or electronic payment platforms. Familiarity with sales tax compliance, use tax, or 1099 preparation. Exposure to month‑end close in a team accounting environment.

You don't just survive chaos, you get better because of it. When things break, change, or move sideways, you don't freeze. You adapt faster than the problem evolves. High Agency. You don't wait to be told what to do. You see the gap, you fill it. If something is blocking progress, you find a way around it, over it, or through it without asking for permission. Executors. Ideas are cheap. We hire people who ship. You're the person who turns a whiteboard sketch into something real while everyone else is still scheduling the next meeting about it. Bias to Action. Perfect is the enemy of done. You'd rather make a decision with 80% of the information and course correct than sit around waiting for 100% that never comes. Speed. We move fast because the opportunity demands it. You're not reckless, but you understand that in this industry, the team that moves fastest wins. And you like winning.
