We focus on modernizing complex back-office systems to create scalable, secure, and high-performing platforms that streamline operations for our clients. As part of our strategic growth, we are focused on platform modernization — transitioning legacy systems to modern, cloud-native architectures that support the scalability, reliability, and high performance of core back- office functions in the insurance domain. Key Responsibilities: Develop and maintain scalable front-end components using React.js and TypeScript. Convert UI/UX designs into responsive, cross-browser compatible web pages using HTML, CSS, and JavaScript. Configure and optimize Webpack for bundling, code splitting, and asset management to improve build performance. Develop and maintain unit tests for React components using Jest and React Testing Library. Collaborate with back-end developers to integrate APIs and services, occasionally working with Node.js on server-side logic. Identify performance bottlenecks in React.js applications, including slow rendering, inefficient data fetching and other issues. Utilize performance testing tools (e.g., Lighthouse, Chrome DevTools Performance tab, JMeter etc) to measure and analyze front-end performance metrics. Collaborate with front-end developers to optimize React.js code for performance, including component optimization, memorization, and virtual DOM diffing. Monitor application performance in various environments, including development, staging, and production. Analyze test results, identify trends, and provide actionable recommendations for performance improvements. Work with DevOps teams to integrate performance testing into the CI/CD pipeline. o Document performance testing processes, methodologies, and best practices. Requirements: Bachelor's degree in computer science, a related technical field, or equivalent practical experience. 5-8 years of experience in performance testing of web applications, with a focus on front-end performance. Strong understanding of core java scripts and React.js architecture, component lifecycle, and rendering process. Proficiency in React.js, including hooks, context API, and component lifecycle. o Strong understanding of JavaScript (ES6+), TypeScript, HTML5, and CSS3. o Familiarity with RESTful APIs and asynchronous request handling. o Experience with version control systems such as Git. Proficiency in using performance testing and profiling tools (e.g., Lighthouse, WebPageTest, Chrome DevTools Performance tab). Experience with React testing libraries (e.g., Jest, React Testing Library). Configure and optimize Webpack for bundling, code splitting, and asset management to improve build performance. Solid understanding of web performance metrics (e.g., First Contentful Paint, Largest Contentful Paint, Time to Interactive). Experience with scripting languages (e.g., JavaScript) for test automation. o Excellent analytical and problem-solving skills. o Strong communication and collaboration skills. Preferred Skills: Exposure to Microservices architecture. o Familiarity with CI/CD pipelines and performance testing integration. Experience with cloud-based testing, particularly on Azure. o Knowledge of server-side rendering (SSR) and its impact on performance. Experience with state management libraries (e.g., Redux, Zustand, React Context) and their performance implications. Soft Skills s Collaboration: Strong problem-solving and analytical skills. Excellent verbal and written communication skills. Communication: Excellent verbal and written communication skills for seamless collaboration. Education: Bachelor's degree or higher in Computer Science, Information Technology, or a related field.
