- Integrate with NestJS services and CMS platforms.
- Build reusable UI components and design-system primitives.
- Implement SEO fundamentals including metadata, structured data, and crawlable rendering.
- Use real-user monitoring, profiling,



and production error tracking to identify regressions.
- Collaborate with backend, DevOps, product, SEO, and editorial teams.
- Own features from design through production deployment and monitoring.

Required Skills & Experience

- Strong production experience with Next.js and TypeScript.
- Hands-on experience with Next.js App Router and modern React architecture.
- Robust understanding of React Server Components.
- Demonstrated experience improving mobile performance and JavaScript bundle size.

- Experience building live or frequently updated content experiences.
- Strong understanding of Core Web Vitals and SEO.
- Experience building API routes, server actions, and typed frontend/backend contracts.
- Experience with production monitoring, RUM, profiling, and error tracking.
- Comfortable working beyond purely frontend responsibilities.

Ideal Candidate

You should have experience operating a content-heavy or high-traffic application where performance, SEO, caching, and reliability directly affect users and business outcomes.
