Senior Front-End Engineer

• Architect and develop large-scale applications using Next.js 16+ (App Router).
• Design systems and reusable component libraries aligned with accessibility and scalability standards.
• Implement modern rendering strategies (static, dynamic, streaming, PPR).
• Leverage Cache Components ("use cache"), revalidateTag(), updateTag(), and cache invalidation strategies effectively.
• Optimize navigation and prefetching strategies (layout deduplication, incremental prefetch).
• Integrate and optimize RESTful APIs with proper caching, error handling, and data consistency.
• Apply advanced browser performance optimization (hydration control, critical rendering path, reflow/repaint minimization).
• Ensure security best practices across Server and Client Components (XSS, CSRF, auth boundaries, RSC attack surface awareness).
• Collaborate with backend and DevOps teams on CDN, edge runtime, and caching-layer strategies.
• Lead code reviews, mentor engineers, and define engineering standards.
