You will work in an Agile/Scrum environment, contributing to sprint planning, peer reviews, and architecture decisions. The role stands apart because it expects you to set frontend coding standards and troubleshoot issues across production environments, not just build screens.

- 6Good understanding of frontend architecture, component design, and state management.
- 7Proficiency with browser developer tools, debugging, performance optimization, plus web security and accessibility best practices.
- 8Familiarity with Git and standard software development workflows.
- 9Strong problem-solving, analytical, and communication skills for code reviews and technical discussions.
- 10Preferred: experience with TypeScript and Redux or similar state-management libraries.
- 11Preferred: experience in Agile/Scrum environments, CI/CD pipelines, cloud-based deployment, and build tools like Vite or Webpack.
Who Should Apply
Frontend engineers with 3-5 years of hands-on ReactJS experience and a record of building reusable UI components will fit well. The role suits people who take ownership of frontend quality and enjoy sharing feedback through code reviews. Developers who avoid architecture discussions or prefer working without cross-browser performance constraints are less suited. Candidates who cannot explain asynchronous JavaScript patterns or lack experience with REST API integration often score low in interviews.
