On-siteEngineeringFull-time

About the role

We are seeking Machine Learning Engineers with strong expertise in generative modeling and large-scale deep learning systems, along with solid software development skills. In this role, you will research, implement, and evaluate world models that learn the dynamics of the physical world from large-scale multimodal data — predicting how a scene evolves under an agent's actions, and serving as a learned simulator for training and evaluating driving and robotic policies.

You will work with state-of-the-art generative architectures, including diffusion and flow-matching models, video tokenizers, and transformer-based multimodal backbones. You will collaborate with a world-class team of experts in computer vision, generative AI, and AI systems, powered by vast amounts of real-world multimodal data from our autonomous fleet and robotics platforms.

Responsibilities

  • Research and develop predictive world models that learn how the physical world evolves, forecasting the future state of a scene from large-scale multimodal driving and robotics data.
  • Develop high-quality multi-view future prediction and generation, supporting both action-conditioned rollouts and formulations that forecast the future without explicit action conditioning.
  • Work at the boundary between world modeling and policy learning: develop architectures in which a shared backbone both predicts the future and produces trajectories or actions, and apply predictive pre-training to improve Vision-Language-Action (VLA) driving performance.
  • Extend prediction beyond 2D pixel into a shared multimodal latent space that spans 3D scene representations such as Gaussian Splatting, together with occupancy and reward signals, so that a single model can support simulation, evaluation, and policy training.
  • Advance cross-embodiment generalization: design unified observation and action representations, together with embodiment-conditioning mechanisms, so that a single world model transfers across vehicles, robots, and sensor configurations with only few-shot data.
  • Define and build the evaluation methodology for predictive world models, spanning representation quality, prediction accuracy, generation fidelity, physical plausibility, long-horizon rollout consistency, and ultimately closed-loop policy performance, then feed the resulting models back into training as a source of synthetic data and corner-case simulation.

Requirements

  • MS or PhD level education in Engineering or Computer Science with a focus on Deep Learning, Computer Vision, Generative Models, or a related field, or equivalent experience. Open to recent graduates.
  • Strong experience in applied deep learning including model architecture design, large-scale model training, data curation, and empirical analysis.
  • 1-3 years + of experience working with DL frameworks such as PyTorch, including hands-on experience with distributed training (FSDP, DeepSpeed, or Megatron-style parallelism).
  • Strong Python programming experience with software design skills.
  • Solid understanding of data structures, algorithms, code optimization and large-scale data processing.
  • Excellent problem-solving skills, including the ability to design controlled experiments and draw sound conclusions from noisy training signals.

Skills

Preferred:

  • Hands on experience with generative models for video or 3D, such as diffusion, flow matching, autoregressive video prediction, or neural scene representations including NeRF and Gaussian Splatting.
  • Experience with world models or learned simulators for decision making, including model-based reinforcement learning and Vision-Language-Action (VLA) models.
  • Experience with multimodal foundation models and video tokenizers or VAEs, including pre-training or adapting large pre-trained backbones.
  • Experience with large-scale training infrastructure and performance optimization, such as mixed precision, torch.compile, kernel-level optimization, and multi-node scaling.
