YOUR CHALLENGE
  • 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

YOUR PROFILE
  • Bachelor's degree in Computer Science, Engineering, or a 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 (e.g., 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 (Webpack 5), 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
