About The Position

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.

Requirements

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.

Nice To Haves

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.

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.
