Role overview
Pax AI is a trade compliance and duty drawback software company that provides an AI-powered “control tower” platform for global trade compliance and tariff refunds. Its platform unifies import and export data, identifies all eligible customs duty, tariff, and fee refunds (duty drawback), and automates the preparation and electronic filing of compliant claims with U.S. Customs and Border Protection. Pax AI is positioned as an intelligence layer for trade compliance operations, using purpose-built AI to operate like a world-class compliance expert, recover every eligible dollar, and increase productivity and accuracy for importers of all sizes. The company focuses on modern, end-to-end duty drawback services and software, offering a TurboTax-like experience that turns complex customs regulations into algorithms so businesses can easily reclaim money that is rightfully theirs.

Why this role is remarkable
- Ship a real feature to production in your first week and take full ownership of an entire product vertical within your first 90 days.
- Work alongside a world-class founding team including a PhD from MIT and repeat founders from Flexport, Brex, TikTok, and Amazon.
