About the Role

What You'll Do

• Shipped real-time 3D in the browser with Three.js / WebGL. We need production work that runs in a browser — not offline renders, not Unity/Unreal-only experience. You will be asked to show interactive, in-browser examples.
• 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.
