  • Write clean, maintainable, and well-documented code.
  • Participate in code reviews and contribute to front-end best practices.
  • Leverage AI-enabled engineering tools to enhance development workflow, testing, and productivity.

Required Qualifications

  • 5+ years of experience in front-end development.
  • Strong expertise in React and modern JavaScript (ES6+).
  • Experience building scalable applications using component-based architecture.
  • Familiarity with microfrontend architecture or modular front-end systems.
  • Experience working with design systems or reusable UI component libraries.
  • Strong understanding of HTML, CSS, and responsive design principles.
  • Excellent communication skills and ability to collaborate in cross-functional teams.

Nice to Have

  • Experience with large-scale enterprise applications.
  • Knowledge of performance optimization techniques.
  • Familiarity with CI/CD pipelines and modern front-end tooling.
  • Experience in FinTech, payments, or POS platforms.
