• Profile and fine-tune applications for maximum loading speed, Core Web Vitals, and smooth rendering on lower-powered mobile devices
• Produce clean, maintainable, and testable JavaScript/TypeScript, perform thorough code reviews, and contribute to our shared UI component library

Requirements

• Advanced knowledge of JavaScript (ES6+), TypeScript, and React
• Hands-on expertise in the Next.js framework (App Router or Pages Router, Server Components)
• Familiarity with modern CSS frameworks or methodologies (e.g., Tailwind CSS, styled-components, CSS Modules)
