• Build and maintain a component library using Storybook for documentation, visual testing, and cross-team collaboration
• Write unit and end-to-end tests with Playwright to ensure feature reliability
• Integrate with backend REST APIs and real-time data feeds (WebSockets, SSE) for live operational displays
• Support internationalization (i18n) with built-in localization for multi-language support

• Understanding of RESTful API consumption, HTTP interceptors, and error handling
• Strong attention to detail and a commitment to delivering accessible, user-friendly interfaces

Preferred Qualifications:

• Experience working in an Nx monorepo with shared libraries and modular application architecture
• Hands-on experience with enterprise data visualization libraries
• Familiarity with Storybook for component-driven development and visual documentation
