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.

  • 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

  • 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)
