• Collaborate closely with product managers and engineers to define and refine key interactions, pushing the boundaries of healthcare technology.

• Contribute to shaping the company's design systems and creating scalable UI components for web and mobile platforms.

📝 Enhancement Note: While the core title is "Senior Product Designer," the description strongly emphasizes a "founding designer" mentality and "high-agency generalist" profile, suggesting this role will have significant autonomy and influence in shaping the early design direction and processes within a growing startup. The mention of "Claude Code" and "TypeScript, React, and CSS" indicates a hands-on approach where design and some level of front-end implementation overlap.

📈 Primary Responsibilities

• Conduct user research and distill insights to inform product strategy and design decisions, ensuring a patient-centric approach.

• Design and prototype user interfaces for Mochi Health's platform, focusing on discoverability of care, transparent pricing, and medication management.

• Collaborate with cross-functional teams, including product managers, engineers, and clinical experts, to ensure design solutions meet business objectives and user needs.

• Own the development of widely-used product features from concept to launch, demonstrating high agency and problem-solving skills.

• Leverage AI design tools and potentially contribute to the implementation of UI components using technologies like TypeScript, React, and CSS.

📝 Enhancement Note: The responsibilities highlight a blend of strategic design thinking and hands-on execution. The emphasis on "shaping the patient experience" and "turning designs into functional UI" suggests a role that requires both strong conceptualization skills and a practical understanding of front-end development constraints and possibilities, particularly with the explicit mention of Claude Code, TypeScript, React, and CSS.

🎓 Skills & Qualifications

Education: While no specific degree is mandated, a strong foundation in design principles, user experience, and human-computer interaction is expected, likely acquired through formal education or equivalent practical experience.

Experience: 3+ years of professional experience in product design, with a demonstrated track record of owning and delivering product features. Experience in a startup environment, particularly as a founding designer, is highly valued.

Required Skills:

• 3+ years of experience in product design roles.

• High proficiency in design tools, specifically Claude Code, Figma, and Framer, demonstrating advanced capabilities in UI/UX design and prototyping.
