Role Overview
We are seeking a Senior Front-End Engineer with deep expertise in 16 to architect and deliver high-performance secure and scalable web applications. The ideal candidate has 5 years of effective front-end experience working on complex production-grade systems and demonstrates strong ownership of architecture performance and browser-level behavior.
Core Responsibilities
- Architect and develop large-scale applications using 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.
