Principal UX Designer

The Principal UX Designer will help build a best-in-class product design team at Quince, shaping UX vision, designing elevated end-to-end experiences, and setting new standards for craft, systems, and usability.

Responsibilities

• Define and drive UX vision across key product surfaces (web, iOS, Android, B2B, and international)
• Lead end-to-end design for core e-commerce experiences — from browsing and PDPs to cart, checkout, and order management — ensuring every touchpoint feels effortless, cohesive, and premium
• Design for a modern luxury brand — bringing aesthetic sensibility and restraint to digital experiences that convey quality and trust
• Partner closely with leadership (President, VP of Product, VP of Engineering, and cross-functional leads) to align UX strategy with business goals
• Introduce and operationalize user testing; define a scalable process for validation, iteration, and insight sharing
• Partner with Product and Analytics to drive experimentation and A/B testing, translating learnings into measurable UX and conversion improvements
• Improve and evolve our design system — refining components, documentation standards, and processes for implementation, iteration, and upkeep
• Help establish a foundation for micro-interactions and motion as part of our UX language, introducing this mindset to the broader team
• Collaborate cross-functionally to balance experimentation, data, and design excellence
• Provide mentorship and feedback to other designers, raising the craft and consistency of the team’s work

Requirements

• 8+ years of product design experience, including e-commerce or consumer-facing platforms
• Proven experience designing for both web and mobile (iOS + Android)
• Deep expertise in UX systems, scalable component libraries, and Figma best practices
• Strong understanding of end-to-end e-commerce journeys (shopping, cart, checkout, and post-purchase flows)
• Experience running or collaborating on user research and usability testing

Key Skills

• Sharp aesthetic sensibility — you can design for a luxury brand and know the difference; you understand how to express craftsmanship, simplicity, and sophistication through digital design
• Thoughtful about micro-interactions, motion, and the small moments that elevate usability and delight
• Curiosity and a strong point of view on how to incorporate AI into the design process — for efficiency, exploration, and insight generation
• Excellent communication and storytelling skills; able to influence and inspire cross-functionally and at the leadership level
