Web Developer

Role: Senior WebGL / OpenGL Engineer - 3D Graphics Location: Bangalore Experience: 3+ years Salary: 25-28 LPA 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: 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 ● Jest, Cypress 3. Performance ● Chrome DevTools, WebGL Inspector, GPU profilers ● Draco, meshoptimizer, KTX2/Basis ● Cloudflare, AWS CloudFront 4. Collaboration ● Git/GitHub ● Technical documentation: shaders, specs, APIs What We’re Looking For: 1.

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 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 ● 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
