  • Staying current with emerging frontend technologies and best practices to drive innovation within the team.
Requirements
  • Strong experience with Angular 17+ or React (or equivalent), leveraging modern JavaScript (ES6+) for building scalable, maintainable, and high-performance applications.
  • Web Accessibility: Deep understanding of web accessibility standards (WCAG 2.1), ARIA roles, keyboard navigation, and screen reader compatibility to ensure applications are usable by people with disabilities.
  • Web Performance Optimization: Proven ability to analyze and improve frontend performance metrics, focusing on Core Web Vitals such as Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). Experience with performance profiling tools and techniques.
  • Form Handling: Expertise in building complex forms, including multi-step wizards, dynamic form controls, validation strategies (both synchronous and asynchronous), and error handling to provide a smooth user experience.
  • Asynchronous Error Handling: Skilled in managing asynchronous operations and error states gracefully within the UI, ensuring robust and user-friendly feedback mechanisms.
