Job Analysis:

The role of UI Developer with React at Brillio is fundamentally about building and maintaining complex, large-scale web applications with a focus on delivering high-quality user interfaces. This position demands a seasoned professional with over 5 years of dedicated experience in ReactJS and associated modern web technologies such as JavaScript, TypeScript, HTML5, and NodeJS. The job’s core responsibility is to engineer scalable, performant, and secure front-end solutions that integrate seamlessly within a microservices-based Java full-stack environment. Beyond just coding, the candidate must demonstrate proficiency in software design principles, version control, CI/CD pipelines, and automated testing, which highlights the importance of delivering robust, production-ready code.
