What you'll do

  • Develop and implement cutting-edge Vision-Language-Action (VLA) models, generalist robot transformers, and imitation learning algorithms (e.g., diffusion policies) to enable robots to autonomously execute complex tasks.
  • Design, test, and refine algorithms to meet the demands of complex real-world autonomy and navigation tasks, with a focus on spatial reasoning and generalization.
  • Streamline the data collection and training workflow to efficiently expand model capabilities with new tasks and data sources.
  • Collaborate with the reinforcement learning team to innovate methods that leverage both simulated and real-world data.
  • Optimize and distill networks for real-time deployment on the edge (e.g. Nvidia Jetson Thor).
  • Build, lead and mentor an exceptional team of software engineers.
  • Provide expert guidance to product managers and executives for strategic decision-making.
  • Create and maintain documentation, guidelines, and best practices to streamline knowledge sharing.

What we're looking for

  • Master's degree or higher in a relevant field such as Engineering, Robotics, or Machine Learning.
  • A minimum of three years of industry or research experience, with PhD experience applicable.
  • Strong deep learning fundamentals including supervised learning, self-supervised learning, Transformer-based architectures, policy optimization algorithms, imitation learning, and generative AI techniques (including Diffusion Models).
  • Proven experience in developing Vision-Language-Action (VLA) models or large-scale generalist robot models (e.g., RT-2, Octo, etc.).
  • Strong background in robotics including autonomy, navigation.
  • Experience with deploying artificial neural networks on hardware platforms.
  • Ability to prototype algorithms and train deep neural networks in Python (Pytorch).

Nice to have

  • PhD degree in Robotics, Engineering, Computer Science, Machine Learning or a similar discipline, or an equivalent amount of research experience.
  • Publications at top-tier conferences.
  • Experience in managing a software team.
  • Ability to write production-level code in modern C++.
