Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced generative AI models.
1. OverviewJoin a leading AI lab's cutting-edge GenAI team and help build foundational AI models from the ground up. We're seeking a talented 3D Generalist with deep, hands-on studio experience in modeling, rigging and animation, Blender-first and comfortable scripting it with Python, to bring real 3D production judgment and elevate the quality of our AI training data. This is a full-time commitment of 40 hours per week.
This is a W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI Lab as part of their extended workforce.
2. Key Responsibilities- Guide research teams to close knowledge gaps and improve AI model performance in 3D modeling, texturing, rigging and animation, and 3D product modeling.
- Design challenging, real-world 3D tasks drawn from studio and client workflows, and produce reference deliverables in editable source formats such as .blend, .fbx, .glb and, where CAD is involved, .step or .stl.
- Evaluate AI-generated 3D assets and give clear, written feedback, catching problems with topology, UVs, materials, scale, skin weights, rig behavior and animation loops.
- Develop guidelines, rubrics and quality checks for 3D work, including scripted mesh, UV and rig checks in Blender Python.
- Collaborate with other subject matter experts to ensure consistency and accuracy in training data.
- 5+ years of shipped 3D work at a game studio, animation or VFX studio, product-visualization or e-commerce 3D team, or creative agency (for example Riot, Ubisoft, Epic, Blizzard, Pixar, Blue Zoo, Framestore, The Mill, Buck, Wayfair, IKEA, Nike, Apple, Threekit); crowd rating, data labeling and personal projects do not count.
- Daily, production-level Blender, with Maya, 3ds Max, ZBrush, Substance Painter or Houdini as secondary tools; you can open a stranger's .blend and diagnose it quickly.
- Python scripting in Blender (bpy): you have written scripts or add-ons that batch, validate, rig, export or otherwise automate production work, and can share them.
- Clean quad topology, retopology of sculpts or scans, UV unwrapping and packing, baking from high to low, and PBR metal-rough texturing at 4K.
- Skeletal rigging and skinning: joint placement, weight painting, IK/FK controls, shape keys, and looping animation exported as .glb or .fbx that plays correctly in a real-time engine or web viewer.
- Fluency with editable source formats: .blend, .fbx, .glb/.gltf, .usd/.usdz, .obj, and CAD exchange formats (.step, .stl, .3dm, .iges); CAD modeling in Rhino, Fusion 360, SolidWorks or FreeCAD is a plus.
- Hands-on use of generative 3D and image tools (for example Meshy, Tripo, Hunyuan3D, Rodin, Luma Genie, Midjourney, Flux) in real work, with a clear view of what their output still gets wrong and the judgment to tell a strong result from a plausible-looking weak one.
- A public portfolio or reel of shipped work on ArtStation, Sketchfab or a personal site, plus a code link for scripts where possible; you will be asked to walk through it.
- Ability to engage reliably for at least 40 hours/week during weekdays.
- Strong written communication skills and the ability to explain creative decisions clearly.
