Responsibilities

• Design, develop, and maintain responsive, accessible, and high‑performing frontend modules using React, TypeScript, and modern JavaScript/HTML/CSS.
• Collaborate closely with product owners, UX designers, backend developers, and QA teams to translate business requirements into efficient, testable, and production‑ready features.
• Champion software engineering best practices—including clean code principles, unit and integration testing (with Jest, React Testing Library), and automated CI/CD pipelines—to ensure quality and stability.
• Lead technical discussions and contribute to architectural decisions around state management (Redux, Context API), component design, routing, performance optimisation, and frontend security.
• Build reusable UI components and design systems to promote consistency and accelerate development across multiple platforms.
• Conduct thorough code reviews to uphold coding standards, accessibility compliance (WCAG), and performance benchmarks.
• Diagnose and resolve complex frontend issues related to rendering, memory leaks, bundling size, or browser compatibility.
• Promote agile and DevOps practices by integrating feedback loops, monitoring tools, and observability into frontend workflows.
• Mentor junior engineers through pair programming, constructive feedback, and knowledge‑sharing sessions on frontend trends, patterns, and secure development practices.
• Stay current with emerging technologies and industry advancements in frontend ecosystems to continuously improve development processes and application capabilities.

Qualifications

• Bachelor's degree in Computer Science, Engineering, or related field; advanced degree preferred.
• Minimum of 6 years of professional software development experience, with at least 4 years focused on React.js‑based frontend development.
• Strong proficiency in React, TypeScript, ES6+, Webpack, and ecosystem libraries (Redux, React Router, Axios, Styled Components).
• Solid understanding of core web technologies: DOM manipulation, event handling, RESTful APIs, asynchronous programming, and cross‑browser compatibility.
• Demonstrated experience with testing frameworks (Jest, Cypress, React Testing Library), version control (Git), and CI/CD integrations.
• Familiarity with micro-frontend architectures, module federation (Webpack5), and monorepo setups (Nx, Turborepo) is highly desirable.
• Knowledge of frontend performance optimisations (code splitting, lazy loading, caching strategies) and SEO considerations for SPAs.
• Understanding of security practices relevant to client‑side development, including XSS mitigation, CSP policies, and secure token handling.
• Proven ability to work independently and collaboratively within agile teams; strong problem‑solving and communication skills.
