Key Responsibilities

  • •Lead research directions in one or more areas of neural graphics, world models, 3D modeling, animation, simulation, or rendering.
  • •Develop, train, adapt, and evaluate AI models and representations for interactive graphics and world-generation systems.
  • •Define data and evaluation strategies connecting model behavior to quality, controllability, coherence, and interactive performance.
  • •Build research prototypes and collaborate with engineering teams to bring successful models into real-time engine workflows.
  • •Analyze results and risks, translate research findings into next steps, and produce reproducible research artifacts while communicating technical direction and mentoring team members.

Key Requirements

  • •PhD/MS (or equivalent) in machine learning, computer graphics, robotics, applied mathematics, or a related technical field.
  • •5+ years of research or industry experience in neural graphics, generative AI, computer graphics, world models, or a closely related domain.
  • •Strong modern ML expertise with depth in model architecture, training, data strategy, evaluation, scaling, and hands-on experience training or adapting generative models (e.g., VAEs, latent tokenizers, diffusion/flow-matching, diffusion transformers, autoregressive, multimodal transformers).
  • •Engineering fluency with ML frameworks such as PyTorch or JAX, including distributed training and pre/post-training tradeoffs.
  • •Deep expertise in at least one AI-for-graphics area (e.g., 3D modeling/representations, animation/motion generation, simulation/neural simulation, rendering/neural rendering, world models/video prediction, or graphics/game-engine workflows).
