If you are passionate about building exceptional consumer products, love making complex things feel simple - and want your craft in the hands of 30M+ users - this role is for you.

What You’ll Do

• Build pixel-perfect user interfaces with React and React Native, simplify complex Web3 interactions, and deliver a seamless experience across mobile and extension.
• Create intuitive, responsive, and accessible user experiences with smooth transitions and usability in mind.
• Develop high-fidelity, interactive prototypes to test and validate ideas for fast iteration.
• Collaborate closely with product designers and engineers to streamline Figma-to-code handoffs and ensure efficient workflows.
• Contribute to the MetaMask design system by building reusable, scalable, and accessible UI components.
• Write clean, optimized code to deliver performant animations, interactions, and frontend experiences.
• Implement accessibility and responsive design best practices, including WCAG compliance and usability testing.
• Document components, workflows, and best practices for collaboration and scalability.

Key Experience for this role

• Solid understanding of modern Javascript/Typescript, with strong proficiency in React & React Native, and experience building interfaces for web and mobile.
• Proven experience building and scaling high-traffic, consumer-facing products with seamless user experiences for millions of active users.
• Experience delivering pixel-perfect, high-fidelity interfaces with attention to detail.
• Expertise in building consistent cross-platform user experiences with a focus on accessibility and performance.
• Hands-on knowledge of design systems, design tokens, and shared component libraries.
• Proficiency in interaction design, animation frameworks (e.g. Rive, Lottie), and optimizing transitions.
• Deep familiarity with Figma, including translating designs into well-structured code.
