Front End Java Developer (UI)

Role Overview

The Senior Front-End Java Developer will join a central UI crew tasked with building high-performance, mobile-first, and web-based experiences. While your primary focus is crafting robust, scalable interfaces using the Angular framework, you will work closely with our backend teams to ensure our front-end architecture is optimized for high-performance data delivery. This role is unique; you will bridge the gap between user-facing components and high-performance backend infrastructure, ensuring our UI can efficiently handle massive data payloads backed by enterprise-grade NVMe flash storage.

Key Responsibilities

• Design, develop, and maintain high-performance, responsive web and mobile applications using Angular.
• Architect front-end components that seamlessly integrate with Java-based microservices, ensuring optimal data streaming and minimal latency.
• Optimize UI performance by leveraging advanced data retrieval patterns, including asynchronous data handling and non-blocking I/O concepts that interface with high-performance storage environments.
• Collaborate with UX/UI designers to translate Figma designs into pixel-perfect, interactive interfaces.
• Work with back-end teams to implement efficient caching strategies, including the use of off-heap memory and high-performance document stores (like Redis) backed by NVMe storage pools.
• Ensure that front-end applications are built to handle high-concurrency requests by utilizing optimized data structures and state management (NgRx, RxJS).
• Contribute to the Design System Management (DSM) to ensure brand consistency and reusable component architecture across all enterprise platforms.
• Troubleshoot and debug complex issues, focusing on application speed, scalability, and seamless integration with high-performance backend data streams.

Required Qualifications/

Skills

• Bachelor’s degree in Computer Science, Information Technology, or related field
• 8\+ years of professional experience in front-end development, specifically in mobile and web environments.
• Strong proficiency in Angular (Angular 16\+ preferred) and TypeScript/JavaScript (ES6\+).
• Experience integrating front-end applications with Java-based microservices architecture and RESTful APIs.
• Understanding of Java NIO (New I/O) concepts (e.g., Direct Buffers and AsynchronousFileChannel) to better communicate with backend teams regarding zero-copy data streaming and throughput efficiency.
• Experience with high-performance caching techniques and familiarity with off-heap memory or in-memory grids (e.g., Ehcache, Redis).
• Expert knowledge of HTML5, CSS3/SCSS, and responsive/mobile-first design principles.
• Proficiency with version control (Git) and design tools (Figma).
• Strong understanding of component-driven development, state management (NgRx, RxJS), and Atomic Design principles.

Preferred Qualifications

• Experience with Design System Management (DSM) platforms.
• Mobile banking or financial services application experience, particularly with high-data-volume interfaces.
• Knowledge of accessibility standards (WCAG 2\.1) and testing frameworks (Jasmine, Karma, Jest).
• Familiarity with DevOps practices, CI/CD pipelines, and cloud-native application development.
• Conceptual understanding of how enterprise storage protocols and NVMe architectures impact end-to-end data delivery speeds in the data center.
