Job description

Use Blender and practical 3D production skills to create AI-training tasks, review model responses, and write clear feedback. This remote role pays up to $125 per hour and offers flexible project-based work.

Contract, part-time

Remote

The work

You will turn real 3D production workflows into tasks that help improve AI models. You will also review AI-generated responses for technical quality and explain what they did well, where they went wrong, and how they could improve.

• Create AI-training tasks based on 3D modeling and content-creation workflows.
• Evaluate AI-generated responses against professional 3D practices.
• Write structured feedback about strengths, errors, and improvement opportunities.
• Use practical knowledge of modeling, UV unwrapping, texturing, shading, rigging, animation, lighting, rendering, and asset export.
• Complete tasks independently and manage your work at your own pace.

What it pays and takes

This is a remote, ongoing, project-based contractor role with flexible task completion and asynchronous work.

• Pay: up to $125 per hour.
• Time: 20+ hours per week.
• Location: Open to candidates in the United States.
• Education: Completed bachelor's degree or higher.
• Experience: At least two years of professional experience using Blender.
• Requirements: Strong written communication, attention to detail, and the ability to explain complex 3D modeling concepts clearly.
• You must be able to work independently in a remote, asynchronous environment.

Helpful background

Experience with several 3D tools or disciplines is helpful. A portfolio of published or shipped 3D work can also support your application.

• ZBrush, Substance Painter, Maya, 3ds Max, Cinema 4D, Unity, Unreal, or Godot.

About AI training work

AI training work uses human judgment to prepare examples, review model responses, and provide feedback that helps artificial intelligence improve. People with practical 3D expertise are valuable because they can judge whether AI-generated work follows real production standards.
