Role Overview:
We’re hiring a Senior Graphics Engineer who is passionate about 3D rendering and
browser-based visual experiences. This is a hands-on WebGL/OpenGL 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:
- 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 - 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 - 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 - 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 - 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 - 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: - 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 - Frontend & Web
● JavaScript / TypeScript
● React, Next.js, familiarity with Vue
● Webpack, Vite, Rollup
● Jest, Cypress - Performance
● Chrome DevTools, WebGL Inspector, GPU profilers
● Draco, meshoptimizer, KTX2/Basis
● Cloudflare, AWS CloudFront - Collaboration

What We’re Looking For: - Must-Haves
● 5-8+ years in graphics programming with deep WebGL/OpenGL 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 - 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
● Familiarity with Unity/Unreal internals
● Background in advanced rendering research
● Knowledge of ray tracing, path tracing
● Experience with photogrammetry or 3D scanning
● Open-source graphics contributions
Technical Challenges You’ll Tackle:
● Achieving photorealistic 60fps rendering on mobile browsers
● Sub-second loading for complex 3D models
● Realistic shaders for different materials (jewelry, fabric, metal, glass)
● Adaptive rendering across low-end to high-end devices
● Seamless AR blending of virtual + real environments
● Managing thousands of product SKUs with diverse materials
● Debugging GPU issues across browsers, devices, and GPU vendors
