Principal Graphic Designer (Experience required in Threejs/ Webgl)

Principal Graphics Engineer\n\nAt iMerit, we're powering some of the world's most advanced AI, Autonomous Vehicle, Robotics, and Mobility programs through cutting-edge data and visualization platforms.\n\nWe're looking for a Principal Graphics Engineer to lead the development of a next-generation browser-based visualization engine for multi-sensor data annotation. This is a hands-on technical leadership role where you'll architect high-performance GPU rendering pipelines and shape the future of real-time 3D visualization.\n\nKey Responsibilities:\n%CF; Design: Architect and optimize WebGPU/WebGL rendering pipelines for large-scale point clouds and sensor-fusion visualization.\n%CF; Performance Optimization: Lead the optimization efforts for rendering massive 3D point clouds (millions of points) in real-time using techniques like frustum culling, level-of-detail (LOD), spatial partitioning (e.g., octrees/k-d trees), and instancing.\n%CF; Shader Development: Design, write, and maintain high-performance, complex GLSL/WGSL shaders for both rendering and compute tasks (e.g., color mapping, depth processing, data manipulation, and custom visualization effects).\n%CF; API Mastery: Serve as the subject matter expert for three.js, WebGL 2.0, and the emerging WebGPU standard.\n%CF; Geometry Management: Expertly manipulate and optimize three.js Primitives (e.g.,BoxGeometry, Points, LineSegments) for memory efficiency and rendering speed, especially when dealing with dynamic annotation tools.\n%CF; Real-Time Processing: Implement on-device data processing, filtering, and transformation logic directly within the GPU compute pipeline, minimizing CPU overhead\n%CF; Code Quality & Architecture: Establish best practices for 3D rendering code, conduct code reviews, and mentor junior developers.\n\nExpertise Required:\n• WebGPU, WebGL 2.0, GLSL/WGSL\n• JavaScript/TypeScript\n• Three.js and custom rendering pipelines\n• Real-time 3D graphics and visualization\n• Point cloud rendering and performance optimization\n• GPU acceleration and shader development\n\nNice to Have:\n• Potree, Open3D, PCL\n• Multi-sensor data processing\n• Docker, Kubernetes\n• Distributed systems and backend services\n\nJoin us to build the visualization engine behind the next generation of autonomous systems and intelligent perception technologies.\n\nIf you're passionate about graphics engineering, real-time rendering, and solving complex visualization challenges at scale, we'd love to hear from you.
