About Customuse

Customuse is building an AI creative engine for image, video, and 3D. We bring leading AI models and pro creation tools into one workflow, helping creators and teams ideate, generate, edit, animate, texture, and produce publish-ready assets.

We are trusted by 15M+ creators and used across gaming, Roblox, animation, ecommerce, product design, architecture, and creative teams. The next chapter is turning Customuse into the default creative workspace for AI-native media production.

We are backed by Connect Ventures, Adjacent, and angels/operators from companies like Snap, Stripe, and SpaceX, with an investor network behind category-defining companies including Revolut and RevenueCat.

Location: London

Type: Full-time

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
