  • Manage real-time data using WebSockets or SSE for quotes and order updates. 
  • Implement forms using React Hook Form + Zod with server-side validation. 
  • Build modular, accessible UIs with Tailwind CSS, shadcn/ui, and Radix Primitives (plus occasional Chakra UI). 
  • Write clean, maintainable, and testable code with TypeScript (strict mode), ESLint, and Prettier. 
  • Ensure quality with Playwright E2E testing, Vitest/Jest, React Testing Library, and accessibility checks. 
  • Contribute to observability and security practices including Sentry, New Relic, CSP with next-safe, secure cookies, and AuthN/AuthZ. 
  • Collaborate closely with cross-functional teams to design and deliver scalable solutions. 

Technical Requirements 

  • 3+ years of experience with React.js and Next.js (minimum 1+ year with Next.js 13/14 App Router). 
  • Strong command of React 18 features: Suspense, streaming SSR, useTransition, useOptimistic, useDeferredValue. 
  • Expertise in Next.js 14 tooling: Server Actions, Route Handlers, Middleware, ISR, revalidation strategies, and caching. 
  • Hands-on experience with performance tuning for mission-critical applications. 
  • Knowledge of trading UX patterns (charts, grids, optimistic UI updates, etc.) is highly desirable. 
  • Strong state management skills with TanStack Query, SWR, and server-driven patterns (RSC + Server Actions). 
  • Experience with forms & validation using React Hook Form + Zod. 
  • Strong understanding of real-time systems using WebSockets or SSE. 
  • Proficiency with Tailwind CSS, shadcn/ui, Radix UI, and component-driven design. 
  • Solid experience in TypeScript with strict typing. 
  • Familiarity with Playwright, Vitest/Jest, React Testing Library.
