About the role

We are looking for an exceptional 3D Engineer to build the technical foundations behind AI-powered 3D asset creation inside Customuse.

You will work on how we generate, transform, optimize, texture, render, and ship 3D assets as part of a broader AI creative engine for image, video, and 3D. This is a role for someone who can move between researchy ambiguity and production systems used by millions of creators.

What you'll do

• Design systems for generating, manipulating, optimizing, and rendering 3D assets at scale

• Build workflows for mesh processing, UVs, materials, textures, rigging, scene composition, and asset conversion

• Work on geometry, topology, transformations, coordinate systems, optimization, and rendering problems

• Prototype ambitious R&D ideas, then turn the strongest ones into reliable product features

• Optimize pipelines for quality, file size, performance, compatibility, and cross-device rendering

• Collaborate with product, AI, design, and engineering to make complex 3D technology feel simple for creators

You might be a fit if

• You have strong experience in 3D engineering, graphics, computational geometry, game engines, simulation, CAD, procedural generation, or related fields

• You understand vectors, matrices, quaternions, transformations, coordinate systems, projections, and spatial reasoning deeply

• You have worked with asset formats and pipelines such as glTF, FBX, OBJ, USD, Blender, game-engine import/export flows, or custom tooling

• You write strong production code, ideally in TypeScript, JavaScript, Python, C++, Rust, or similar

• You care about performance, numerical robustness, asset quality, and user experience

Bonus points

• PhD, research, or advanced academic work in graphics, geometry processing, computer vision, simulation, robotics, ML, or related fields

• Experience with generative AI for 3D, image-to-3D, text-to-3D, procedural generation, or neural rendering

• Experience with Three.js, WebGL, WebGPU, OpenGL, Vulkan, Metal, Unity, Unreal, Blender scripting, Houdini, or USD

• Experience building tools for game studios, UGC platforms, avatar systems, Roblox, Fortnite/UEFN, creator marketplaces, browser, or mobile

What we offer

• Competitive salary and stock options

• Real ownership from day one on a product used by millions of creators

• Work at the intersection of AI, media creation, gaming, 3D, and creative tools

• A small, ambitious team with direct feedback, high trust, and high standards

• Central London office

Hiring process

• Screening call

• Role-specific interview

• Practical working session or case study

• Culture fit interview and meet the team

• Reference check and offer

We value ambition and trajectory over years of experience. We move quickly and hold a high bar, but you will get real ownership, direct feedback, and the chance to do career-defining work with a small, ambitious team.
