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
