Responsibilities:

• Develop and maintain high-quality, responsive, and user-friendly web applications using React.js and its ecosystem (e.g., Redux, Context API, React Router).
• Collaborate with back-end developers to integrate front-end applications with Java RESTful APIs, ensuring efficient data exchange and robust error handling.
• Implement pixel-perfect UIs from design mockups and wireframes, ensuring cross-browser compatibility and optimal performance.
• Design and build intuitive user interfaces for modern applications that interact with LLM-powered solutions, including chat interfaces, data visualization, and interactive AI outputs.
• Work closely with product managers, UX/UI designers, and other stakeholders to understand requirements and translate them into technical specifications and elegant user experiences.
• Ensure application scalability, security, and maintainability by adhering to coding standards, performing code reviews, and contributing to architectural discussions.
• Implement and maintain unit, integration, and end-to-end tests to ensure the reliability and quality of the applications.
• Optimize front-end performance for speed and responsiveness, addressing issues like load times, rendering, and interactivity.
• Stay up-to-date with emerging front-end technologies, React.js advancements, and best practices in UI/UX design.
• Participate in the entire software development lifecycle, from concept and design to testing and deployment.

Required Qualifications:

• Bachelor's degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience.
• 5+ years of professional experience in front-end web development, with significant experience in React.js.
• Strong proficiency in JavaScript (ES6+), HTML5, and CSS3, including modern CSS frameworks or preprocessors (e.g., SASS, styled-components, Tailwind CSS).
• Demonstrable experience integrating front-end applications with back-end Java RESTful services.
• Familiarity with state management libraries (e.g., Redux, Zustand) and client-side routing.
• Experience with version control systems (e.g., Git).
• Solid understanding of modern web development build tools (e.g., Webpack, Vite).
• Ability to debug complex front-end issues and optimize performance.
• Excellent problem-solving skills, attention to detail, and a commitment to writing clean, maintainable code.
