Job summary

HCLTech is seeking a graphics-focused engineer to design and optimize materials for real-time rendering. You will handle PBR workflows, glTF asset pipelines, and shader work while targeting low-end hardware for broad compatibility.

You will also contribute to VFX systems and collaborate with React Three Fiber components to integrate assets runtime, ensuring efficient performance on constrained devices.

Qualifications

• Proficiency with PBR workflows, metalness/roughness, IBL and transmission for glass/liquids.
• Experience with glTF/GLB export, optimization, and clean node naming for runtime binding.
• Strong sense of triangle budgets, texture memory, draw calls and frame time.

Responsibilities

• Author and optimize materials for real-time rendering.
• Manage glTF asset pipeline from modeling to export.
• Optimize for low-end hardware and ensure efficient rendering performance.
• Write and modify GLSL shaders for materials/effects.
• Develop real-time VFX/particle systems with budget-conscious approaches.
• Collaborate with frontend stack using JSX/React Three Fiber to integrate assets.

Job description

We are HCLTech, one of the fastest-growing large tech companies in the world and home to 223,000+ people across 60 countries, supercharging progress through industry-leading capabilities centered around Digital, Engineering and Cloud.

About the Role

What You'll Do

• PBR material authoring — deep, practical command of metalness/roughness workflows, environment maps / image-based lighting, and transmission/refraction for transparent materials like glass and liquid.
• glTF / GLB asset pipeline — modeling or sourcing (Blender or equivalent), optimization (decimation, LOD, texture atlasing), and clean export with a sane node hierarchy and naming that downstream code can bind to.
• Real-time performance discipline — you think in triangle budgets, texture memory, draw calls, and frame time as a matter of habit, and you optimize for low-end hardware, not just your own workstation.
• GLSL shader ability — you can write and modify shaders for materials and effects, not only wire up premade ones.
• Real-time VFX / particle systems — believable, cheap effects (fluids, smoke/vapor, flames, splashes).
• Enough code fluency to collaborate in our stack — you can read and lightly modify JSX / React Three Fiber, and you understand how your assets are consumed at runtime.

Strongly preferred:

• Experience with React Three Fiber specifically (not just vanilla Three.js).
• A track record optimizing for constrained devices (mobile, Chromebooks, low-end GPUs).
• Scientific, technical, medical, or educational visualization experience — anywhere accuracy of the depicted object mattered as much as its beauty.
• Comfort taking real-world reference seriously and getting proportions and details right.
