Job description

The Work

You will review video footage of robots, mechanical systems, tools, machines, components, and physical tasks. Your annotations will help AI systems understand what objects do, how parts move, and how tasks unfold.

You will work independently, follow project instructions, and provide clear feedback when a video or annotation is difficult to interpret.

• Review footage showing robotic systems, mechanical components, tools, machines, and physical interactions.
• Annotate objects, movements, actions, components, positioning, mechanical interactions, and task sequences.
• Identify details about motion, component behavior, and how mechanical parts and systems interact.
• Check annotations for accuracy, consistency, completeness, and alignment with project standards.
• Flag incorrect or unclear annotations using your mechanical engineering judgment.
• Give clear feedback on difficult or ambiguous video examples.

What It Pays and Takes

This is part-time contractor work listed as entry level, although the role requires at least two years of relevant experience. Previous AI training or annotation experience is not required.

• Pay: $50 to $90 per hour.
• Hours: 20 or more hours per week.
• Work type: Part-time contractor role.
• Location: Applicants must be based in an eligible country for this role.
• Language: Good written English is required.
• Experience: At least two years in mechanical engineering, mechanical design, manufacturing, robotics, or a related field.
• Knowledge: Practical understanding of mechanical components, tools, machines, physical systems, movement, and interaction.
• Requirements: Strong attention to detail, ability to follow detailed instructions, and an independent working style focused on accuracy, consistency, and completeness.
• Helpful background: Experience with SolidWorks, NX, Creo, or CATIA.
• Also helpful: Exposure to robotics, automation, manufacturing, industrial equipment, video annotation, data labeling, AI training, or computer vision.

About AI Training Work

AI training is the human work behind systems that learn from examples, including labeled video showing objects, actions, and movement. People with practical engineering knowledge are paid to spot details and errors that general reviewers may miss.
