Role Overview:
We’re hiring a WebGL/Three.js Engineer who is passionate about 3D rendering and browser-based visual experiences. This is a hands-on WebGL/Three.js role where you’ll own the rendering pipeline - from 3D asset ingestion to advanced shaders and real-time lighting.
You will build high-performance, photorealistic, and smooth 60fps experiences across devices, crafting custom rendering solutions that push the limits of WebGL.
What You’ll Build:
1\. 3D Rendering & Visualization:
– Develop and optimize real-time 3D viewers running at 60fps across all devices
– Implement advanced rendering: PBR, IBL, shadows, reflections
– Create custom shaders for metals, glass, fabrics, transparency, and complex materials
– Build dynamic lighting systems for photorealism
– Implement AR placement and real-world environmental rendering
– Add post-processing effects: bloom, AO, depth of field, color grading
– Build interactive 3D configurators with real-time customization
2\. Performance Optimization:
– Optimize 3D asset loading for near-instant initial render
– Implement LOD systems, shader optimization, and efficient resource usage
– Use compression pipelines: geometry, textures, KTX2/Basis
– Implement frustum & occlusion culling, instancing, and batching
– Profile GPU memory, draw calls, and shader performance
– Build adaptive quality settings based on device capabilities
3\. 3D Asset Pipeline & Tools:
– Build loaders/parsers for glTF, USDZ, OBJ, FBX
– Implement asset optimization: UV mapping, normal maps, texture atlasing
– Create mesh-processing tools: decimation, smoothing, tangents
– Build progressive loading, caching, and streaming systems
– Develop debugging and visualization tools for asset inspection
4\. Interactive Controls & UI Features:
– Implement camera systems: orbit, pan, zoom, animated transitions
– Build gestures for mobile: pinch, rotate, drag
– Create 360° product viewers with fluid interactions
– Add hotspots, annotations, measurement tools, and view presets
– Enable screenshot and recording functionalities
5\. WebXR & AR Experiences:
– Implement WebXR VR/AR experiences directly inside browsers
– Build AR Quick Look integration for iOS
– Integrate AR.js / 8th Wall for seamless web AR
– Implement environment lighting estimation and hit testing
– Build cross-platform AR for iOS + Android
6\. Graphics Systems Architecture:
– Architect custom WebGL rendering solutions from scratch
– Build material/shader libraries and rendering modules
– Create scene graph management systems
– Build modular systems with reusable rendering utilities
– Design APIs for frontend integration and customization
Technical Stack:
1\. Graphics & Rendering:
– WebGL 1.0/2.0, OpenGL ES, GLSL
– 3D formats: glTF 2.0, USDZ, OBJ, FBX, Collada
– Tools: Blender, RenderDoc, Spector.js
– Texture tools: Sharp, ImageMagick, compression utilities
2\. Frontend & Web:
– JavaScript / TypeScript
– React, Next.js, familiarity with Vue
– Webpack, Vite, Rollup

What We’re Looking For:
1\. Must-Haves:
– 5-8+ years in graphics programming with deep WebGL/Three.js knowledge
– Strong understanding of the full rendering pipeline
– Expert in GLSL: vertex, fragment, compute shaders
– Mastery of PBR, material systems, and physically accurate lighting
– Proven experience building high-performance 3D web apps
– Strong JavaScript/TypeScript skills
– Solid understanding of 3D math: matrices, vectors, quaternions
– Experience with 3D formats, UV mapping, texture workflows
– Ability to debug GPU issues and optimize across browsers/devices
– Ability to build custom WebGL engines from scratch
2\. Highly Desirable:
– Experience with Three.js/Babylon.js (plus, not required)
– E-commerce and 3D configurator experience
– WebXR development experience
– Strong mobile optimization knowledge
– Experience with GPU compute, GPGPU
