Senior WebGL / Three.js / Babylon.js Developer

We are seeking a highly skilled Senior WebGL / Three.js / Babylon.js Developer with a passion for building cutting-edge 3D experiences on the web. In this role, you will take full ownership of the rendering pipeline—from 3D asset ingestion to advanced shader development and real-time lighting systems.

You will design and develop high-performance, photorealistic 3D applications that run smoothly (60 FPS) across multiple devices and platforms.

Key Responsibilities

1. 3D Rendering & Visualization

• Develop real-time 3D applications optimized for performance across devices
• Implement advanced rendering techniques including:
  • Physically Based Rendering (PBR)
  • Image-Based Lighting (IBL)
  • Shadows, reflections, and post-processing effects
• Create custom shaders for materials like glass, metal, fabric, and transparent surfaces
• Build interactive 3D configurators with real-time customization
• Develop dynamic lighting systems for realistic visual output
• Implement AR-based visualization and real-world rendering experiences

2. Performance Optimization

• Optimize 3D assets for fast loading and smooth rendering
• Implement Level of Detail (LOD), batching, and instancing techniques
• Use compression tools like KTX2/Basis for textures and geometry
• Profile GPU performance, memory usage, and draw calls
• Build adaptive rendering systems based on device capability

3. 3D Asset Pipeline & Tools

• Build loaders and parsers for formats such as glTF, USDZ, OBJ, and FBX
• Optimize assets through UV mapping, texture atlasing, and mesh processing
• Create tools for mesh decimation, smoothing, and debugging
• Develop streaming, caching, and progressive loading systems

4. Interactive UI & Controls

• Implement camera systems (orbit, zoom, pan, transitions)
• Enable mobile gestures such as pinch, rotate, and drag
• Build 360° viewers and interactive product experiences
• Add annotations, hotspots, measurement tools, and presets
• Enable screenshot and recording features

5. WebXR & AR Development

• Build browser-based VR/AR experiences using WebXR
• Integrate AR solutions for iOS and Android platforms
• Implement environment lighting, hit testing, and AR placement
• Ensure seamless cross-platform AR experiences

6. Graphics System Architecture

• Design and build custom WebGL rendering engines
• Develop reusable shader libraries and rendering modules
• Create scalable scene graph systems
• Build APIs for frontend integration and customization

Required Skills & Qualifications

Must-Have Skills

• 4–8+ years of experience in graphics programming
• Strong expertise in WebGL / OpenGL and rendering pipelines
• Advanced knowledge of GLSL (vertex & fragment shaders)
• Strong proficiency in JavaScript / TypeScript
• Hands-on experience with React.js
• Deep understanding of:
  • 3D math (vectors, matrices, quaternions)
  • Material systems and PBR workflows
• Proven experience building high-performance 3D web applications
• Ability to build custom WebGL engines from scratch

Preferred Skills

• Experience with Three.js or Babylon.js
• Exposure to WebXR and AR technologies
• Experience in e-commerce or 3D configurators
• Knowledge of GPU optimization and GPGPU techniques
• Familiarity with Unity or Unreal Engine internals
• Understanding of ray tracing or path tracing
• Experience in photogrammetry or 3D scanning

Technical Stack

• Graphics: WebGL 1.0/2.0, OpenGL ES, GLSL
• Frontend: JavaScript, TypeScript, React, Next.js
• Tools: Blender, RenderDoc, Spector.js
• Performance: Chrome DevTools, GPU profilers
• Compression: Draco, meshoptimizer, KTX2/Basis
• Collaboration: Git, technical documentation

Eligibility Criteria

• Candidates must have experience in SaaS, product-based companies, or startups/scale-ups
• Candidates from large consulting firms or MNC environments are not preferred
• Strong problem-solving mindset and attention to detail required

Key Challenges You Will Solve

• Achieving photorealistic rendering at 60 FPS on mobile devices
• Handling large-scale 3D assets with fast load times
• Building adaptive rendering for low-end to high-end devices
• Creating realistic materials and lighting systems
• Debugging GPU issues across multiple browsers and platforms

Work Environment

• Location: Bengaluru
• Work Mode: 5 days Work From Office + Saturday Work From Home
• Industry: SaaS
• Culture: High-performance engineering, detail-oriented, and innovation-driven

Why Join This Role

• Work on advanced graphics engineering (not generic frontend tasks)
• Solve complex rendering challenges
• Build visually impactful products used at scale
• Collaborate with a highly skilled engineering team
• Opportunity to work with cutting-edge WebGL technologies
