About AI Training Work

AI training is the human side of building modern artificial intelligence. Experts contribute real-world judgment, creative input, evaluation, and technical feedback that help AI systems learn how people create, assess, and use digital content.

This work is remote and can offer flexible part-time schedules. Your rigging knowledge can help shape AI systems working with character design, animation, simulation, and hand movement.

The Role

OpenTrain is recruiting a Rigging 3D Expert specializing in hand and finger articulation for a character and hand design project. You will apply advanced rigging skills to create high-quality input for AI training while helping develop functional, expressive, and realistic character movement.

This is a remote contractor role requiring 20 or more hours per week. The listed compensation range is $15 to $80 per hour, with work conducted in English.

• Employment type: Contractor and part-time
• Work arrangement: Remote, worldwide
• Time requirement: 20+ hours per week
• Language: English
• Pay range: $15 to $80 per hour

What You'll Do

You will create and evaluate rigging solutions for complex hand and finger articulation, balancing technical performance with realistic or stylized movement. The work includes both hands-on implementation and clear communication with creative and technical stakeholders.

• Create, implement, and refine hand-focused character rigs for 3D animation and simulation.
• Collaborate with creative and technical stakeholders to align rig functionality with the project vision.
• Deliver precise weight painting, joint placement, and deformation solutions for realistic and stylized hand movement.
• Troubleshoot rigging issues and optimize rigs for animation fluidity and usability.
• Document rigging processes and workflows to support knowledge transfer.
• Provide written and verbal feedback on rigging assignments.

Requirements and Helpful Background

This opportunity is marked as entry level, but the project requires proven expertise in character rigging and complex hand and finger articulation. You should be comfortable delivering detailed remote project work and explaining your decisions through strong written documentation and verbal communication.

• Proven expertise in character rigging with complex hand and finger articulation.
• Advanced proficiency in Maya, Blender, or similar 3D software.
• Strong understanding of hand anatomy and functional rigging.
• Exceptional written and verbal communication and documentation skills.
• Experience delivering remote project work.
• Familiarity with scripting or automation for rigging pipelines is helpful.
• A detail-oriented mindset and passion for character mechanics and user-focused design are helpful.

Why This Work Matters

Every major AI system depends on carefully prepared human input. In this project, your expertise in character mechanics and hand articulation can help AI systems better understand and generate sophisticated 3D movement.

AI training is a fast-growing field that lets specialists work at the cutting edge of technology from anywhere with a computer and internet connection.
