Job description

At 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.

Key Responsibilities:

• Design: Architect and optimize WebGPU/WebGL rendering pipelines for large-scale point clouds and sensor-fusion visualization.
• 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.
• 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).
• API Mastery: Serve as the subject matter expert for three.js, WebGL 2.0, and the emerging WebGPU standard.
• 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.
• Real-Time Processing: Implement on-device data processing, filtering, and transformation logic directly within the GPU compute pipeline, minimizing CPU overhead
• Code Quality & Architecture: Establish best practices for 3D rendering code, conduct code reviews, and mentor junior developers.
• Three.js and custom rendering pipelines
• Real-time 3D graphics and visualization
• Point cloud rendering and performance optimization
• GPU acceleration and shader development
