Senior WebGL/Three.js Developer

Ctruh; Bengaluru; On-site; INR 2,500,000 - 4,000,000; Full time

Job summary

Ctruh is hiring a WebGL/Three.js Engineer to own the rendering pipeline, from asset ingestion to shaders and real-time lighting. You will craft high-performance, photorealistic 60fps experiences across web and mobile, building custom rendering solutions that push WebGL limits.

You’ll develop advanced rendering systems, optimize assets and GPU usage, and contribute to a scalable graphics toolchain. Strong JS/TS skills and deep shader knowledge are essential for delivering production-grade 3D

Qualifications

• 4–8+ years of experience in graphics programming with strong WebGL/Three.js expertise.
• Deep understanding of rendering pipelines, GLSL shaders, PBR, and 3D graphics fundamentals.
• Strong JavaScript/TypeScript skills with experience building high-performance 3D web applications.
• Hands-on experience with 3D asset pipelines, optimization, and cross-platform performance tuning.
• Ability to debug GPU-related issues and architect custom WebGL-based solutions.

Responsibilities

• Build and optimize high-performance real-time 3D/WebGL experiences across web and mobile platforms.
• Build advanced rendering systems including PBR materials, custom shaders, lighting, shadows, reflections, and post-processing effects.
• Design and implement interactive 3D viewers, configurators, camera controls, and immersive user experiences.
• Optimize graphics performance through asset compression, LODs, batching, culling, caching, and GPU profiling.
• Develop and maintain 3D asset pipelines supporting formats such as glTF, USDZ, FBX, and OBJ.
• Build WebXR and AR experiences, including browser-based AR/VR, environment lighting, and cross-platform mobile AR.
• Architect scalable graphics systems, rendering modules, shader libraries, and reusable frontend integrations.

Job description

About Us

Ctruh is a deep-tech company building the infrastructure layer for the spatial internet through a proprietary browser-native, no-code 3D engine and VersaAI, our in-house generative AI engine that transforms text, images, and video into production-ready 3D assets in minutes.

Our Work Rhythm

This is a 6-day working setup with Monday to Friday operating from office and Saturday as Work From Home (WFH). We believe this model enables stronger collaboration, faster learning, and better team alignment while maintaining flexibility.

About The Role

We’re hiring a WebGL/Three.js Engineer who is passionate about 3D rendering and browser-based visual experiences. This is a hands-on WebGL/Three.js 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 Own

• Build and optimize high-performance real-time 3D/WebGL experiences across web and mobile platforms.
• Build advanced rendering systems including PBR materials, custom shaders, lighting, shadows, reflections, and post-processing effects.
• Design and implement interactive 3D viewers, configurators, camera controls, and immersive user experiences.
• Optimize graphics performance through asset compression, LODs, batching, culling, caching, and GPU profiling.
• Develop and maintain 3D asset pipelines supporting formats such as glTF, USDZ, FBX, and OBJ.
• Build WebXR and AR experiences, including browser-based AR/VR, environment lighting, and cross-platform mobile AR.
• Architect scalable graphics systems, rendering modules, shader libraries, and reusable frontend integrations.

Must-Haves

What You Bring

• 4–8+ years of experience in graphics programming with strong WebGL/Three.js expertise.
• Deep understanding of rendering pipelines, GLSL shaders, PBR, and 3D graphics fundamentals.
• Strong JavaScript/TypeScript skills with experience building high-performance 3D web applications.
• Hands-on experience with 3D asset pipelines, optimization, and cross-platform performance tuning.
• Ability to debug GPU-related issues and architect custom WebGL-based solutions.

Good-to-Have

• Experience with Three.js/Babylon.js
• 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

You think in shaders and understand the rendering pipeline end-to-end. You’ve built custom rendering systems without relying on frameworks. You’re fluent in transformation matrices, BRDFs, tangent spaces, and GPU memory patterns. You ship production-quality 3D experiences, optimize relentlessly, and care deeply about visual craft, performance, and engineering precision.

Why Join Ctruh

You’ll work on pure graphics engineering, not generic frontend development, solving complex rendering challenges that push the boundaries of WebGL. Build visually stunning experiences seen by millions of users while leveraging modern WebGL 2.0 capabilities and advanced graphics techniques. Join a high-performance engineering culture that encourages experimentation, where your work directly impacts customer engagement. You'll have access to high-end GPUs, devices, and cutting-edge graphics tools, while building technology backed by NVIDIA, Microsoft, and Google.
