ReactJS UI Developer - Financial Systems

As a Javascript/ReactJS Developer, your role involves designing, developing, and maintaining high-performance front-end applications supporting trading, risk, and research workflows. You will build responsive, data-intensive UIs using ReactJS, JavaScript (ES6+), HTML/CSS, and the Browser API. Additionally, you will implement real-time data visualization and interaction features optimized for low-latency environments and integrate seamlessly with backend systems via WebSockets and REST APIs to deliver live market data and trading updates. Collaboration with KDB, Java, and Kafka engineers is essential to ensure robust data flow and efficient UI-backend interaction. Applying modern React design patterns such as hooks, context, and state management is crucial for building scalable and maintainable components. Performance tuning, debugging, and profiling are necessary to ensure smooth operation under production trading loads, and working directly with traders, quants, and technology teams to translate workflow requirements into intuitive, reliable user interfaces is also part of your responsibilities. Key Responsibilities: - Design, develop, and maintain high-performance front-end applications supporting trading, risk, and research workflows. - Build responsive, data-intensive UIs using ReactJS, JavaScript (ES6+), HTML/CSS, and the Browser API. - Implement real-time data visualization and interaction features optimized for low-latency environments. - Integrate seamlessly with backend systems via WebSockets and REST APIs to deliver live market data and trading updates. - Collaborate closely with KDB, Java, and Kafka engineers to ensure robust data flow and efficient UI-backend interaction. - Apply modern React design patterns (hooks, context, state management) to build scalable, maintainable components. - Conduct performance tuning, debugging, and profiling to ensure smooth operation under production trading loads. - Work directly with traders, quants, and technology teams to translate workflow requirements into intuitive, reliable user interfaces. Qualifications: - Bachelors degree in Computer Science, Software Engineering, or a related technical discipline. - Expert-level proficiency in ReactJS, JavaScript (ES6+), HTML/CSS, and browser-based development. - Deep understanding of React UI architecture and design patterns, as well as commonly used JavaScript patterns. - Proven experience integrating UIs with real-time backend services (developing and debugging WebSockets and REST APIs). - Working knowledge of Node.Js for tooling or lightweight backend integration. - Experience with JavaScript testing frameworks (e.g., Jest, Mocha, Cypress). - Strong grasp of front-end performance optimization, cross-browser compatibility, and secure web application practices. - Ability to operate effectively in a fast-paced trading or financial technology environment with high standards for reliability and latency. Preferred Skills: - Experience working with AWS for deployment or service integration. - Exposure to Electron, Progressive Web Apps (PWA), or Glue42 integration technologies used in trading desktop environments. - Familiarity with streaming data systems (e.g., Kafka) and real-time event-driven architectures. - Understanding of financial markets, market data, or order/trade workflows. - Strong communication skills and a collaborative mindset suited to small, high-impact teams in a hedge fund setting.
