About the role

Key responsibilities & impact

Build and maintain our real-time Three.js and React Three Fiber rendering engine.
Implement and optimize rendering features: lighting (lightmaps, HDR and image-based lighting, ambient occlusion), anti-aliasing, materials, and post-processing.
Integrate Gaussian splat captures alongside traditional mesh-based 3D content.
Write and debug GLSL shaders and custom materials.
Develop camera systems, navigation, waypoints, and scene interaction.
Own the 3D asset pipeline: glTF and GLB optimization, Draco and mesh compression, KTX2 and Basis texture conversion, and lightmap baking.
Profile and optimize for frame rate, memory, and load time across constrained devices (tablets, kiosks) and large displays.
Use spatial structures (BVH) for fast raycasting, picking, and pathfinding.
Build diagnostics and debug tooling that keep visual quality and performance measurable.
Partner with full stack and web developers to expose clean, well-documented renderer APIs to the web app.
Work with 3D-capture, content, and design teams to bring real spaces and designs into the engine.
Contribute to the Nx monorepo with strong testing, code review, and documentation.
Help define the technical direction of immersive and photoreal experiences.

Requirements

What you’ll need
