Superpower is a health platform on a mission to extend and enhance human life, offering lab testing, data aggregation, AI-powered clinical insights, and wellness products. The company has grown 10x in the past six months and is backed by top-tier healthcare and tech investors including Forerunner Ventures, 8VC, and founders/partners from DoorDash, Khosla Ventures, and Founder's Fund.
As a Design Engineer, you will shape and build the interfaces through which members understand and manage their health. You will collaborate closely with designers and product engineers to turn complex health information into clear, intuitive experiences, taking ideas from early prototypes through production. This is a hands-on role combining design judgment with engineering depth to influence how the product looks, feels, and works.
You will work primarily in React and TypeScript, with ownership of the details that make an experience feel considered: typography, layout, motion, interaction, and performance.
Key responsibilities include:
- Design and build intuitive interfaces for core member journeys, from understanding health results to navigating ongoing care
- Collaborate with product, design, and clinical teams to translate complex information into clear, accessible experiences
- Create interactive prototypes to explore ideas, test assumptions, and help the team choose a direction
- Build and maintain reusable components and interaction patterns that improve consistency across the product
- Own interface quality across responsive layouts, loading and error states, accessibility, and performance
- Work with backend and mobile engineers to integrate real data, ship complete experiences, and improve them through feedback and product usage
The tech stack includes React, TypeScript, HTML, CSS, Tailwind CSS, Storybook, Figma, Linear, Notion, and Slack. This is an in-person role based in San Francisco where you will work closely with product, design, clinical, and engineering teammates.
QUALIFICATIONS:
- A portfolio of interfaces you have designed and built, demonstrating your personal contribution, technical decisions, and attention to detail
- Strong experience with React, TypeScript, HTML, CSS, and modern frontend development practices
- Excellent visual and interaction design judgment, including typography, hierarchy, spacing, and motion
- The ability to explore ideas in Figma or code, explain your decisions, and work constructively through critique
- Experience building production interfaces that handle real data, different screen sizes, accessibility needs, and edge cases
- Demonstrated ability to own work independently from prototype through release, including testing and debugging code developed with AI tools
- An interest in healthcare, wellness, or longevity is a strong plus
