The opportunity

Build the interfaces that carry a ten-year-old product into its next decade. You will own React components end to end — from a design file to a fast, accessible screen in production — working directly with backend, product and design rather than through layers of process. Early ownership is the norm here, not a reward for tenure.

What you'll do

• Develop responsive and reusable UI components using React.js.
• Build and integrate REST APIs with frontend applications.
• Write clean, maintainable, and reusable JavaScript/TypeScript code.
• Implement responsive designs using HTML5, CSS3, and modern UI practices.
• Manage application state using React Hooks and state-management patterns.
• Debug UI issues and optimize application performance.
• Collaborate with Backend, Product, Design, and QA teams.
• Participate in code reviews and follow frontend development best practices.

Must-have qualifications

• 6 months+ / 1+ year of experience in frontend or UI development.
• Hands-on experience with React.js.
• Strong knowledge of JavaScript (ES6+).
• Good understanding of HTML5, CSS3, the DOM, and responsive design.
• Experience working with REST APIs and JSON.
• Understanding of React Hooks, component lifecycle, and state management.
• Familiarity with Git and version control.
• Good problem-solving and debugging skills.

Nice to have

• Experience with TypeScript.
• Familiarity with Redux or the Context API.
• Knowledge of Next.js.
• Understanding of frontend performance optimization and browser debugging tools.
• Exposure to UI/UX principles and design systems.
