Pax helps retailers, manufacturers, and wholesalers get refunds when they pay tariffs. We’re building the control center for U.S. duty drawback—a $10B/year opportunity hiding in plain sight. We use AI and automation to recover tariffs paid by importers when goods are later exported, returned, or destroyed. Most companies don’t even realize they’re eligible. We make sure no dollar is left behind.
Tariffs have been top of mind for everyone. Companies have gone from paying 25% to 145% tariffs. There’s never been a better time to make a real world impact on real businesses.
We’re well-capitalized and looking for a founding engineer to take core ownership of our product.
What you’ll do:
The ideal candidate:
We’re a small team by design. Your work will shape the future of the company—and the $10B+ industry we’re transforming. This will be the most fulfilling work of your career.
We work from San Francisco, in-person. Our office is focused, fast, and full of energy.
If you’ve built something you’re proud of, we want to see it.
