Javascript前端開發工程師

### **Job Summary** We are seeking a skilled **Frontend Design Engineer** to develop and optimize user interfaces for specialized devices with real-time video streaming, control, and monitoring requirements. This role focuses on building responsive, performance-critical interfaces tailored for industrial machines, embedded systems, and camera-based platforms. --- ### **Key Responsibilities** * Design and develop modern frontend interfaces using HTML5, CSS3, JavaScript/TypeScript, and frameworks like React, Vue.js, or Angular * Optimize UI performance for live video streaming (RTSP, WebRTC, MJPEG, HLS) and real-time control * Create device-specific dashboards, controls, and monitoring pages for HMI panels or IPCs * Collaborate with backend and embedded system engineers to integrate APIs, video feeds, and command protocols * Implement efficient rendering techniques for low-latency video playback and data visualization (e.g., charts, heatmaps) * Adapt UI behavior to work on both web and embedded touchscreen environments * Conduct UI performance profiling and apply optimizations (DOM rendering, memory usage, buffering strategies) * Ensure cross-browser and cross-device compatibility * Design and maintain a component library with reusable widgets (e.g., camera control, zoom/pan, alert panels) * Participate in UI/UX testing, usability improvements, and localization/internationalization --- ### **Requirements** * Bachelor’s degree in Computer Science, Human-Computer Interaction, or related field * 2+ years of frontend development experience, ideally with video streaming interfaces or hardware-based UI systems * Proficiency in HTML/CSS/JS and frontend frameworks (React preferred) * Experience with WebSocket, WebRTC, RTSP-over-web, or low-latency streaming pipelines * Knowledge of UI optimization strategies for embedded platforms or devices with constrained resources * Familiarity with RESTful APIs, JSON, and real-time messaging protocols (MQTT, SignalR, etc.) * Understanding of modern UI/UX principles, responsive layouts, and touchscreen interactions * Strong debugging and performance profiling skills in Chrome/Edge/Firefox DevTools --- ### **Preferred Qualifications** * Experience with thermal/RGB camera UIs, NVR/DVR systems, or AI/vision-based UI applications * Familiarity with hardware control panels (zoom, focus, PTZ, etc.) via frontend interfaces * Exposure to embedded browser environments (Qt WebEngine, Electron, Chromium Embedded) * Experience integrating image enhancement sliders (gamma, contrast, CLAHE, etc.) * Knowledge of Tailwind CSS, Material UI, or other design systems * Familiarity with cross-language interfacing (e.g., Python/C++ backend to JS frontend via WebSocket) --- ### **Work Conditions** * Hands-on testing and UI integration with physical devices or camera systems * Work closely with firmware, backend, and hardware teams * May require occasional travel to support system integration or customer validation * Fast-paced development cycles in high-performance imaging and control environments
