Internship Motion Capture Actor Jobs in New York

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 AI models.

A leading AI lab is building a performance transfer model: one that takes an actor's original performance and carries it faithfully into a new output, holding on to the timing, the emotion, and the small physical choices that make it feel real. The team believes AI should honor the craft of performance, not flatten it.

To get the evaluation right, we are bringing in senior character animators to help define what "good" looks like, critique the current evaluation approach, and shape the pool of reviewers who score model outputs.

This is a part-time W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI Lab as part of their extended workforce.

• Establish evaluation standards: Define clear criteria for when a performance has been captured well, both in emotional resonance and physical fidelity, and point out where current evaluations fall short.
• Curate benchmarks: Identify strong examples of performances that are easy to capture and ones that are genuinely hard, so the model has meaningful tests to measure against.
• Shape the evaluation pool: Help define the right profile, expertise mix, and rubric for the human reviewers who assess outputs at scale.
• Collaborate with other experts: Work alongside fellow subject-matter experts to keep evaluations consistent and accurate.

• 4+ years as a hands-on character animator, with human or character _performance_ as your core craft.
• Verifiable credits on 2 or more feature films, animated features, or AAA game cinematics at recognized studios.
• Direct experience with facial animation and/or performance capture facial keyframe work, motion-capture solving, cleanup or motion editing, or character technical design of facial and performance rigs.
• A meticulous eye for micro-expressions, emotional beats, and the subtleties that make a human performance feel authentic.
• AI proficiency: familiarity with AI tools and workflows, including the ability to generate your own visual samples for testing and comparison.
• The ability to translate complex visual details into clear, precise language that can be captured in data captions and evaluation templates.
• Able to come on-site in Playa Vista (Los Angeles), CA or New York, NY for in-person working sessions once or twice a month.
• (Optional) Reliable access to a 4K-resolution monitor for precise, pixel-level review.

This role is specifically for animators whose primary craft is character performance. It is not a fit for directors of photography, lighting or camera specialists, colorists, compositors, editors, or generalist 3D artists. Layout, previsualization, environment and effects work will not qualify on their own.
