Web Developer

Role: Senior WebGL / OpenGL Engineer - 3D Graphics

Location: Bangalore

Experience: 3+ years

Salary: 25-28 LPA

Role Overview:

Were 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 youll

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 Youll 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:

Technical documentation: shaders, specs, APIs

What Were 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)

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 Youll 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
