Job description

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.

1. Overview

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, keeping the timing, the emotion and the small physical choices that make it feel real. We're looking for senior character animators who have spent their careers bringing acting to life on feature films, VFX and games, to help define what a well transferred performance looks like and judge where the model gets it right or wrong.

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.

2. Key Responsibilities

Set the quality bar: Define clear standards for when a performance has been carried over well, in body mechanics, facial nuance, timing and emotional intent, and point out where current evaluations fall short.

Critique model outputs: Review generated performances shot by shot, the way you would in dailies, and write precise, actionable notes.

Build benchmarks: Choose reference performances that range from easy to genuinely hard to capture, so the model is tested on what matters.

Shape the reviewer pool: Help define the profile, rubric and calibration for the human reviewers who score outputs at scale.

Collaborate with other experts to keep evaluations consistent and accurate.

3. Core Qualifications

10+ years as a hands-on character animator focused on human and character acting, at Senior, Lead or Principal level.

Animator credits on several feature films, VFX features or AAA game cinematics at recognized studios (e.g., Sony Pictures Imageworks, ILM, Animal Logic, Laika, Pixar, Disney, DreamWorks, Framestore, MPC, DNEG, Weta FX).

A sharp eye for micro expressions, lip sync, weight and timing, and the small acting choices that make a performance feel authentic.

Strongly preferred: facial animation experience, and recent work in real-time engines (Unreal or Unity), VR/XR, or performance capture pipelines.

Hands-on use of generative image and video tools (e.g., Sora, Veo, Midjourney, Runway, Kling) to create your own samples for testing and comparison.

Able to work on-site in Playa Vista (Los Angeles), CA or New York, NY for in-person working sessions once or twice a month.

Strong written communication and the ability to turn visual detail into clear, precise language for evaluation templates.
