The Mission
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.
What We Are Looking For
• 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).
Nice-to-Have & Plus Skills
• 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.
Key Responsibilities
• 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.
