Company

Roblox builds a platform and tools for creating and experiencing 3D digital environments and user-generated content.

What you will do

• Architect, scale, and optimize pipelines for processing meshes, textures, rigs, and animations at high volume.
• Develop graphics-driven systems to detect geometry exploits, malicious topologies, rendering hacks, and visual artifacts.
• Build automated solutions that improve 3D asset quality, rendering performance, and avatar schema compliance.
• Apply computational geometry, rendering, skinning, and animation expertise to define validation constraints.
• Collaborate with machine learning, engine, and product teams on asset processing across the avatar ecosystem.

Requirements

• BS, MS, or PhD in Computer Science, Computer Graphics, or a related technical field, or equivalent experience.
• Expertise in 3D mathematics, linear algebra, computational geometry, rendering pipelines, shading, and lighting.
• Hands-on experience with 3D meshes, topology, UVs, vertex structures, and geometric processing.
• Understanding of animation, rigging, skinning weights, and skeletal hierarchies.
• Strong programming skills in C++, Luau, Python, or similar production languages, including scalable systems and data pipelines.
• For US-based roles, certain US visa categories may not be supported, and future H-1B sponsorship may not be available.

Nice to have

• Experience developing or optimizing runtime game-engine features.
• Experience with automated 3D asset optimization, decimation, LOD generation, or procedural geometry.
• Familiarity with machine learning algorithms for 3D asset processing.
