Senior WebGL/Three.js/Babylon.js Developer

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 devicesImplement advanced rendering: PBR, IBL, shadows, reflectionsCreate custom shaders for metals, glass, fabrics, transparency, and complex materialsBuild dynamic lighting systems for photorealismImplement AR placement and real-world environmental renderingAdd post-processing effects: bloom, AO, depth of field, color gradingBuild interactive 3D configurators with real-time customization2. Performance Optimization:Optimize 3D asset loading for near-instant initial renderImplement LOD systems, shader optimization, and efficient resource usageUse compression pipelines: geometry, textures, KTX2/BasisImplement frustum & occlusion culling, instancing, and batchingProfile GPU memory, draw calls, and shader performanceBuild adaptive quality settings based on device capabilities3. 3D Asset Pipeline & Tools:Build loaders/parsers for glTF, USDZ, OBJ, FBXImplement asset optimization: UV mapping, normal maps, texture atlasingCreate mesh-processing tools: decimation, smoothing, tangentsBuild progressive loading, caching, and streaming systemsDevelop debugging and visualization tools for asset inspection4. Interactive Controls & UI Features:Implement camera systems: orbit, pan, zoom, animated transitionsBuild gestures for mobile: pinch, rotate, dragCreate 360° product viewers with fluid interactionsAdd hotspots, annotations, measurement tools, and view presetsEnable screenshot and recording functionalities5. WebXR & AR Experiences:Implement WebXR VR/AR experiences directly inside browsersBuild AR Quick Look integration for iOSIntegrate AR.js / 8th Wall for seamless web ARImplement environment lighting estimation and hit testingBuild cross-platform AR for iOS + Android6. Graphics Systems Architecture:Architect custom WebGL rendering solutions from scratchBuild material/shader libraries and rendering modulesCreate scene graph management systemsBuild modular systems with reusable rendering utilitiesDesign APIs for frontend integration and customizationTechnical Stack:1. Graphics & Rendering:WebGL 1.0/2.0, OpenGL ES, GLSL3D formats: glTF 2.0, USDZ, OBJ, FBX, ColladaTools: Blender, RenderDoc, Spector.jsTexture tools: Sharp, ImageMagick, compression utilities2. Frontend & Web:JavaScript / TypeScriptReact, Next.js, familiarity with VueWebpack, Vite, RollupJest, Cypress3. Performance:Chrome DevTools, WebGL Inspector, GPU profilersDraco, meshoptimizer, KTX2/BasisCloudflare, AWS CloudFront4. Collaboration:Git/GitHubTechnical documentation: shaders, specs, APIsWhat We’re Looking For:1.
