- Make architectural decisions that enable accessibility, performance, consistency, and maintainability across the UI stack.
- Improve UI build and test workflows.
- Optimize build performance, bundling strategy, and package versioning for the component library.
- Maintain tooling for testing and dependency management of the UI app.
Requirements
- Strong experience building modular, composable, and well-documented component libraries and/or design systems.
- Deep knowledge of React, TypeScript, HTML, and CSS.
- Familiarity with styling approaches (CSS Modules, CSS-in-JS, Tailwind, Sass, etc.).
