The ideal candidate is a front-end expert who writes clean, maintainable code, embraces modern JavaScript and TypeScript best practices, and cares deeply about performance and pixel-perfect execution. You should thrive in collaborative environments, working closely with product designers and backend engineers to deliver exceptional user experiences.

• Create reusable, composable components with clear patterns for state management, styling, and data flow.
• Integrate applications with REST or GraphQL APIs and efficiently manage complex asynchronous data flows.
• Conduct thoughtful, constructive code reviews focused on quality and maintainability.
• Optimize rendering performance and load times through best practices in caching, lazy loading, and efficient DOM operations.
• Support UI consistency and scalability by contributing to component libraries or design systems.
• Maintain strong Git workflows, collaborating effectively through pull requests.
• Participate in sprint planning, grooming, and retrospectives, contributing insights to drive continuous improvement.

Required Qualifications

• Bachelor’s degree in Computer Science, Engineering, or equivalent professional experience.

• Proven ability to convert Figma/design mockups into production-ready UI.
• Solid understanding of Git workflows and code review best practices.
