About the Role

You will develop generative methods for physically grounded 3D environments. You will build, train, optimize, and evaluate models for reconstruction, view synthesis, and world generation; experiment with 3D representations; develop training pipelines and loss functions; and improve model quality and robustness.

Requirements

  • Strong fundamentals in deep learning and generative models
  • Understanding of diffusion models and transformers
  • Understanding of camera geometry, depth, reconstruction, point clouds, meshes, or Gaussian splats
  • Proficiency in Python and PyTorch
  • Experience with model training and optimization
  • Ability to implement research papers and run experiments
  • Strong coding skills for scalable ML systems

Responsibilities

  • Design and develop generative 3D machine-learning methods
  • Build, train, optimize, and evaluate models for 3D reconstruction, novel-view synthesis, and world generation
  • Implement 3D representations including point clouds, meshes, and Gaussian splatting
  • Develop training pipelines and loss functions
  • Integrate physics-aware priors and world-model capabilities
  • Analyze model performance, debug failures, and improve quality and robustness
