Review code, mentor other engineers, and contribute to a culture of high engineering standards and continuous improvement. Requirements: 8+ years of experience in front-end development, with a strong technical background and experience influencing architecture. Expert-level knowledge of JavaScript and TypeScript. Hands-on experience designing and delivering micro-frontends and modernizing legacy front-end architectures. Strong understanding of building scalable, high-performance web applications. Experience aligning technical solutions with business and delivery goals. Advanced knowledge of modern build tools such as Webpack, Vite, or Rollup. Solid testing experience, including unit and end-to-end testing (Jest, Testing Library, Vitest, or similar). Deep understanding of design systems and component-driven development (Storybook, design tokens). Strong CSS knowledge, including preprocessors (SASS / LESS) and responsive layouts. Experience working with CI/CD pipelines and tools like GitHub Actions, Jenkins, or Terraform. Familiarity with backend technologies and microservices architectures is a plus. Nice to have: Knowledge of web accessibility standards (WCAG) and internationalization (i18n). Experience building offline-ready applications and implementing graceful degradation strategies.
