Senior WebGL/Three.js/Babylon.js Developer

Location : Bengaluru | SaaS Product Company

6 Days Working (MonFri WFO | Sat WFH)

Role Overview :

Were looking for a hardcore graphics engineer who lives and breathes real-time 3D rendering on the web.
This is not a typical frontend role you will own the complete rendering pipeline, building high-performance, photorealistic WebGL experiences that run seamlessly across devices at 60 FPS.

What Youll Work On : 3D Rendering & Visualization :

- Build real-time 3D viewers with smooth 60fps performance

- Implement advanced rendering: PBR, IBL, shadows, reflections

- Develop custom shaders (metal, glass, fabric, transparency)

- Create dynamic lighting systems for photorealism

- Build interactive 3D configurators

- Add post-processing: bloom, AO, DOF, color grading

Performance Optimization :

- Optimize asset loading & rendering performance

- Implement LOD systems, batching, instancing

- Apply compression: KTX2, Basis, Draco

- Perform GPU profiling (draw calls, memory, shaders)

- Enable adaptive quality based on device capability

3D Asset Pipeline :

- Work with formats: glTF, USDZ, OBJ, FBX

- Optimize assets: UV mapping, textures, mesh processing

- Build progressive loading & streaming pipelines

- Develop debugging and asset inspection tools

Interactions & UI :

- Build camera systems (orbit, zoom, pan)

- Implement mobile gestures (pinch, drag, rotate)

- Create 360 viewers & interactive product experiences

- Add annotations, hotspots, measurement tools

WebXR & AR :

- Build browser-based AR/VR experiences

- Implement WebXR & AR integrations (iOS + Android)

- Work on real-world lighting & hit testing

Graphics Architecture :

- Design custom rendering engines

- Build shader/material libraries

- Create scene graph & reusable rendering modules

- Develop scalable APIs for frontend integration

Tech Stack :

- Graphics : WebGL 1.0/2.0, OpenGL ES, GLSL

- Frontend : TypeScript, React, Next.js

- Tools : Blender, RenderDoc, Spector.js

- Performance : Draco, meshoptimizer, KTX2/Basis

- Testing & Build : Webpack, Vite, Jest, Cypress

Ideal Candidate Profile :Must-Have :

- Strong understanding of rendering pipeline & 3D math

- Expertise in GLSL shaders (vertex & fragment)

- Experience building high-performance 3D web applications

- Strong debugging skills across browsers & GPU environments

Good to Have :

- Experience with Three.js / Babylon.js

- Exposure to WebXR / AR

- Knowledge of ray tracing / GPU compute

- Experience in 3D configurators / e-commerce visualization

- Background in Unity / Unreal internals

- Contributions to open-source graphics projects

Key Challenges :

- Achieving photorealistic rendering at 60fps (mobile + web)

- Handling heavy 3D models with sub-second load time

- Building adaptive rendering across device types

- Debugging across different GPUs, browsers, environments

Why This Role? :

- Pure graphics engineering role (no generic frontend work)

- Work on cutting-edge WebGL rendering problems

- Build visually stunning, high-impact products

- High ownership in a performance-driven engineering culture

- Opportunity to push limits of browser-based 3D

Team : Small, highly skilled graphics engineering
