Stampli is building finance software in a new way: AI-native, grounded in real financial workflows, and shaped by people who understand the work deeply. We are looking for a Principal UX Expert who can develop a deep understanding of the people we build for — from finance teams to procurement, reimbursement, and card-holding employees across the business, and the executives who decide whether to buy. Your job is to ensure we understand the persona and the problem before solutions are designed, so the right questions are asked early and UX gaps are caught before Design Review.

This is a senior individual-contributor role reporting to the VP of Product. You will be a leading source of US customer insight inside Product — close to the market, close to Sales and Customer Success, and a trusted partner to our Product Managers and design team. You will work alongside our design leadership, learning from each other and raising the bar on how deeply we understand our users and decision-makers.

This is not primarily a production-design role. Your impact comes from sharp customer insight, strong product judgment, and the ability to challenge and coach the teams around you. You may also work hands-on with wireframes, prototypes, and other design artifacts when that is the most effective way to test an idea or improve a solution.
