  • Design and iterate on the vision-language-action model architecture, including the VLM backbone, action decoder, and multimodal fusion pipeline.
  • Build and optimize large-scale training infrastructure, including distributed training, data pipelines, mixed-precision, and efficient fine-tuning.
  • Develop simulation-based evaluation and closed-loop training workflows using photorealistic neural rendering.
  • Curate and manage multimodal training datasets spanning real-world driving and synthetic scenarios.
  • Translate research in diffusion, flow matching, reasoning-augmented VLAs, and world models into production-grade systems.
  • Collaborate with vehicle systems and controls engineers to integrate model outputs into a real-time autonomous driving stack.
  • Support architecture decisions, large-scale training, simulation evaluation, and deployment on trucks across the full model development lifecycle.

Requirements

  • MS or PhD in Computer Science, Machine Learning, Robotics, or a related field, or equivalent industry experience.

  • Track record of publications at top ML/robotics venues such as NeurIPS, ICLR, ICRA, or CoRL, or significant open-source contributions (preferred).
  • Familiarity with sim-to-real transfer, photorealistic simulation, or neural rendering for driving scenes (preferred).
  • Experience with reinforcement learning, imitation learning, or learning from demonstration in embodied settings (preferred).
  • Comfort operating as an early team member with high ownership, low ego, and fast iteration (preferred).

Benefits

  • Base salary plus benefits and equity compensation.
  • Salary determined by role, level, location, qualifications, skills, and experience.
