Your work will influence how hundreds of engineers build, improving consistency, performance, and the overall developer experience.</p> <p>This is a hands-on role. You’ll build components, help define UI architecture, and partner with engineers and designers to turn ideas into scalable UI systems. In practice, you’ll push the UX layer forward, enabling teams to ship high-quality features without reinventing core patterns.</p> <h2>What You’ll Do</h2> <ul> <li>Evolve front-end architecture, including component libraries, layout patterns, theming, and global UI behaviors.</li> <li> <p>Implement specialized UI components where needed (e.g., editors, grids, structured data components) with a focus on performance and usability.</p> </li> <li> <p>Ensure components support accessibility, keyboard interaction patterns, and internationalization/localization standards.</p> </li> <li> <p>Support product teams in adopting UI Platform components and patterns, providing guidance and identifying opportunities to simplify or extend the platform.</p> </li> <li> <p>Contribute to documentation, developer tooling, and internal processes that make it easier to build high-quality UI consistently.</p> </li> <li> <p>Identify UI-related technical debt or architectural gaps and proactively drive improvements.</p> </li> <li> <p>Mentor other engineers, participate in design reviews, and influence technical decision-making.</p> </li> </ul> <h2><strong>About You</strong></h2> <ul> <li> <p>You enjoy creating clean, scalable components and UI patterns that others depend on.</p> </li> <li> <p>You think beyond features and consider how systems evolve. You take ownership of problems, not solutions. </p> </li> <li> <p>You communicate clearly and listen effectively.
