Skills
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
