Design end-to-end point-of-sale experiences for restaurant staff across terminal and handheld surfaces. Translate complex workflows such as ordering, payments, splits, modifications, and voids into fast, reliable, error-resistant interfaces. Partner with product, engineering, and research teams; conduct discovery, create prototypes and high-fidelity designs, address edge cases, communicate tradeoffs, and use research and business metrics to guide decisions. The role requires strong visual design, autonomy, collaboration, and an AI-first approach.
