Principal UX Expert

Stampli•Nashville, TN

4d•Hybrid

About The Position

Stampli is seeking a Principal UX Expert to develop a deep understanding of the people who use, administer, buy, and make decisions about its finance software. This senior individual-contributor role is a leading source of US customer insight within Product, working closely with Sales, Customer Success, Product Managers, design, and Product Marketing. The role reports to the VP of Product and works alongside design leadership. The focus is on understanding personas and problems before solutions are designed, asking the right questions early, and identifying UX gaps before Design Review. This is not primarily a production-design role: impact comes from customer insight, product judgment, and the ability to challenge and coach teams. The role may also contribute hands-on wireframes, prototypes, and other design artifacts when useful for testing ideas or improving solutions. The Principal UX Expert will conduct ongoing research, validate personas and problems throughout product development, maintain persona libraries, and operationalize them through AI-powered UX evaluation tools. The role will also contribute to product copy and messaging, and partner on Product-Led Growth and Product-Led Sales experiments. The position offers a hybrid schedule based in the Austin office three days per week, with remote work for the remainder of the week.

Requirements

10+ years of experience in UX, product design, service design, user research, or product strategy, with a track record of turning customer insight into shipped product.
A proven approach to deep user research, including customer calls, recorded onboardings and demos, and behavioral analytics such as FullStory, and the ability to turn research into actionable insight.
Senior in-house UX experience at a high-craft B2B SaaS product, or experience at a top-tier design or product consultancy; in either setting, remained accountable through implementation, launch, and iteration.
Deep understanding of finance personas and workflows, such as accounts payable, procurement, controllership, ERP, or fintech, and how these personas work, make decisions, and evaluate solutions.
Ability to apply persona and business-context understanding to product copy, UX copy, and messaging.
Experience with growth experimentation and strong understanding of growth levers across Product-Led Growth and Product-Led Sales.
Strong systems thinking and product judgment, with the ability to challenge teams constructively and work hands-on with wireframes and prototypes when useful.
Comfort working across Product, Design, Sales, Customer Success, and Product Marketing, and across US and Israel time zones.
Hands-on experience structuring research into reusable persona libraries, evaluation criteria, and AI workflows, including building or configuring agents, skills, guardrails, and evaluators for research, prototyping, and product-quality assessment.

Responsibilities

Run ongoing user research to understand Stampli’s users, buyers, administrators, and decision-makers, including where the product resonates and where prospects push back.
Partner with Product Managers from feature initiation through Product Review to validate target personas and problems, clarify workflows, and define intended outcomes.
Partner with Product Managers and designers from feature initiation through Design Review, bringing customer context, challenging assumptions, and surfacing persona gaps, missing scenarios, and usability risks.
Build and maintain persona libraries and operationalize them through AI-powered UX evaluation tools, including agents, skills, guardrails, and evaluators.
Use persona libraries and AI tools to assess product concepts, prototypes, and designs throughout discovery and development.
Create or contribute to wireframes and prototypes when hands-on exploration is the most effective way to test a concept, communicate a recommendation, or improve a solution.
Partner with Product Marketing to shape product and UX copy and messaging using persona and business-context understanding.
Partner with Product and Product Marketing on Product-Led Growth and Product-Led Sales experiments, helping identify suitable flows for features, upsells, decision-makers, and business contexts.
