We are looking for a Senior Frontend Developer (React.js) on behalf of one of our high-growth client teams to lead the architecture, optimization, and scaling of their user-facing web applications. In this role, you will be responsible for transforming complex product designs into highly interactive, modular, and pixel-perfect digital experiences. You are a perfect candidate if you are growth-oriented, you love what you do, and you enjoy working on new ideas to develop exciting products.
5+ years of professional engineering experience, with 3+ years focused deeply on building scale-ready applications with React.js and TypeScript.
Expert-level understanding of state management ecosystems, knowing exactly when to utilize global tools (Redux Toolkit, Zustand) versus server-cache managers (React Query/ZandStack Query) and native Context.
Deep familiarity with modern React frameworks, specifically Next.js, including a strong functional understanding of Server-Side Rendering (SSR), Static Site Generation (SSG), and React Server Components (RSC).
Proven track record of identifying and fixing web performance bottlenecks—handling layout shifts (CLS), minimizing bundle sizes via code-splitting, optimizing re-renders, and mastering Core Web Vitals.
A strong commitment to automated testing, utilizing tools like Jest, React Testing Library, and Cypress/Playwright to maintain high regression confidence.
Exceptional eye for UI polish and layout implementation, with a solid commitment to semantic HTML and web accessibility standards (WCAG/ARIA).
Experience with monorepo setups (Turborepo, Nx) or distributed micro-frontend architectures.
Exposure to modern CSS paradigms (Tailwind CSS, CSS Modules) and managing enterprise-grade design systems.
Background in backend integration, web sockets, or serverless functions (Node.js).
Familiarity with continuous integration and continuous deployment pipelines (CI/CD) for single-page applications.
Design and develop scalable, reusable, and secure component architectures and custom React hooks that accelerate overall development speed.
Audit and refactor legacy code blocks to optimize Core Web Vitals, payload sizes, and client-side rendering pipelines.
Interface directly with Backend and Product teams to define clean REST or GraphQL API schemas, ensuring efficient data orchestration.
Lead by example through rigorous code reviews, driving typing standards, linting rules, and design pattern uniformity across the team.
Act as an internal sounding board for modern frontend tooling, assisting junior and mid-level developers in refining their React and engineering skills.
