• Conduct thorough code reviews and provide constructive technical feedback to team members
• Drive technical decision-making for component architecture and implementation patterns
• Serve as a subject matter expert for engineering teams integrating with the design system
• Collaborate with UX architects, product designers, and QA engineers to ensure components meet our design and engineering standards
• Monitor integration support channels and provide timely technical assistance
• Create and maintain comprehensive component documentation, including usage guidelines, API specifications, and integration examples
• Proactively gather feedback from consuming teams and iterate on components to improve developer experience
• Document patterns and best practices to enhance the overall developer experience
• Provide short demos showcasing your work and new component capabilities
• Implement and maintain CI/CD pipelines for automated testing and quality assurance
• Support multiple initiatives by providing essential UI components and UX patterns
• Mentor junior engineers and provide technical guidance on design system best practices
