Stampli is building AI-native finance software grounded in real financial workflows. As Principal UX Expert, you will be a senior individual contributor reporting to the VP of Product, responsible for developing deep customer insight across finance teams, procurement, reimbursement, and executive buyers.
Your primary impact comes from sharp customer insight, strong product judgment, and the ability to challenge and coach teams—not production design. You will run ongoing user research to understand Stampli's users, buyers, and decision-makers, identifying where the product resonates and where prospects push back. You'll partner closely with Product Managers to validate target personas and problems from feature initiation through Product Review, clarifying real workflows and intended outcomes.
You will work alongside design leadership to raise the bar on user understanding, bringing customer context to design reviews, challenging assumptions, and surfacing persona gaps and usability risks. You'll build and maintain Stampli's persona libraries and operationalize them through AI-powered UX evaluation tools—including agents, skills, guardrails, and evaluators—that assess product concepts and designs throughout discovery and development.
When hands-on exploration is most effective, you'll create wireframes and prototypes to test concepts and communicate recommendations. You'll partner with Product Marketing to shape product and UX copy based on deep persona understanding, and collaborate on Product-Led Growth and Product-Led Sales experiments to identify the right flows for each feature and decision-maker.
You bring 10+ years in UX, product design, service design, user research, or product strategy, with a track record of turning customer insight into shipped products. You have proven expertise in deep user research—customer calls, recorded sessions, behavioral analytics—and the ability to translate findings into actionable insight. You have senior in-house UX experience at a high-craft B2B SaaS product or a background at a top-tier design consultancy, remaining accountable through implementation and iteration.
You have deep understanding of finance personas and workflows—accounts payable, procurement, controllership, ERP, or fintech—and can understand how these personas work, decide, and evaluate solutions. You're comfortable applying persona and business-context understanding to product and UX copy. You have experience with growth experimentation and understand Product-Led Growth and Product-Led Sales levers. You demonstrate strong systems thinking and product judgment, work well across Product, Design, Sales, Customer Success, and Product Marketing, and are comfortable across US and Israel time zones. You have hands-on experience structuring research into reusable persona libraries and AI workflows, including building or configuring agents and evaluators.
