• Collaborate closely with engineers to ship SDK features, onboarding flows, and other customer-facing improvements.
• Elevate quality standards by conducting design reviews, ensuring accessibility, performance, and platform-native feel.
• Lead end-to-end design for new features and improvements – from user research and ideation through prototyping, visual/UI design, and iterative refinement.
• Drive innovation and excellence in design: establish best practices and maintain a world-class design system.
• Mentor and collaborate with other designers to foster a high-performance, user-focused design culture.
