Principal UX Expert

Stampli•Nashville, TN

5d•$160,000 - $180,000•Hybrid

About The Position

Stampli is seeking a Principal UX Expert to build deep understanding of the people who use, administer, buy, and make decisions about its finance software. The role ensures teams understand personas and problems before designing solutions, ask the right questions early, and identify UX gaps before Design Review. It is a senior individual-contributor role reporting to the VP of Product and serves as a leading source of US customer insight within Product. The position partners closely with Sales, Customer Success, Product Managers, design, and Product Marketing. This is not primarily a production-design role. Its impact comes from customer insight, product judgment, and the ability to challenge and coach teams. The role may also work hands-on with wireframes, prototypes, and other design artifacts to test ideas or improve solutions. The Principal UX Expert conducts ongoing research; validates personas, problems, workflows, and outcomes; and brings customer context into product and design reviews. The role also builds persona libraries and AI-powered UX evaluation tools, contributes to copy and messaging, and supports Product-Led Growth and Product-Led Sales experiments. The position offers a hybrid schedule based from Stampli’s 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 findings into clear, actionable insight.
Senior in-house UX experience at a high-craft B2B SaaS product or experience at a top-tier design or product consultancy, with accountability through implementation, launch, and iteration.
Deep understanding of finance personas and workflows, such as accounts payable, procurement, controllership, ERP, or fintech, including 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 a strong understanding of Product-Led Growth and Product-Led Sales levers.
Strong systems thinking and product judgment, constructive challenge skills, and ability to work hands-on with wireframes and prototypes when useful.
Comfort working across Product, Design, Sales, Customer Success, and Product Marketing, including 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 and clarify workflows and 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.
Create or contribute to wireframes and prototypes when hands-on exploration is useful for testing concepts, communicating recommendations, or improving solutions.
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, identifying suitable flows for features, upsells, decision-makers, and business contexts.
