 Senior Frontend Engineer

Job Description

To build a high-performance, responsive interface that masks the latency of VLM inference and provides a seamless "pro-grade" chat experience.
Key Responsibilities
  • Real-time Streaming: Implement robust Server-Sent Events (SSE) or WebSockets to handle "streaming tokens," ensuring the text appears naturally as the model generates it.
  • Optimistic UI & Loading States: Design sophisticated "Skeleton" loaders and progress indicators for image uploads so the app feels fast even when the GPU is busy.
  • Multi-modal State Management: Manage complex chat histories that include large images, bounding box overlays (if the VLM does object detection), and markdown-heavy text.
  • Image Processing (Client-side): Implement client-side image compression and resizing (using Canvas/WebWorkers) to reduce the payload size before it hits your server, saving bandwidth and improving upload speed.
  • Responsive AI Design: Ensure the "Vision" aspect of the chat works perfectly on mobile handling camera inputs and touch-based image interactions.
Must-Have Skillset
  • Frameworks: Next.js or React.js (Expert level) with a focus on performance optimization.
  • State Management: Experience with Zustand, TanStack Query (React Query), or Redux Toolkit for caching and syncing server state.
  • Communication: Deep understanding of HTTP streaming, Buffer handling, and async patterns.
  • Visuals: Tailwind CSS for rapid UI development and Framer Motion for smooth, non-distracting animations.
  • Asset Handling: Experience with cloud storage SDKs (S3/Vercel Blob) for direct-to-cloud image uploads.
