About the role

Keyframe animation takes a skilled artist 2 weeks to produce 10 seconds of realistic character motion. Our procedural animation system generates physically plausible motion in real time from text descriptions. Tell it "character stumbles on uneven terrain while carrying a heavy box" and it produces motion that looks hand-crafted — no keyframes, no motion capture, no manual cleanup. The underlying tech combines physics simulation with learned motion priors trained on 400 hours of motion capture data. Your role is pushing the quality frontier: improving foot contact, reducing floating artifacts, handling complex multi-character interactions, and adding style transfer so the same action looks different for different character archetypes. We sell to game studios and VFX houses who need large volumes of unique motion. Quality matters more than speed — our clients will wait 30 seconds for great motion, but won't accept motion that looks robotic. You'll work alongside two research scientists and three engineers, and you'll have access to our full motion capture dataset for training.

Fully remote.

Responsibilities

  • Improve procedural animation quality for foot contact and physical plausibility
  • Develop style transfer capabilities for character-specific motion generation
  • Build evaluation metrics that correlate with human quality judgments
  • Optimize motion generation for multi-character interaction scenarios
  • Integrate new motion capture data into training pipelines
  • Collaborate with research scientists to implement published motion synthesis techniques

Requirements

  • 5+ years in graphics, animation, or physics-based ML
  • Experience with motion synthesis, character animation, or physics simulation
  • Strong PyTorch skills and understanding of generative models
  • Familiarity with reinforcement learning for control or locomotion
  • Portfolio or publications demonstrating animation or motion generation work

Benefits

  • Fully remote with occasional LA studio visits for mocap sessions
  • Top-tier compensation
  • Health and dental from day one
  • Annual $4,000 equipment budget
  • Flexible schedule with no fixed hours
