Job Description
Our fleet of delivery robots operates globally, generating vast amounts of real‑world data. By utilizing Vision‑Language‑Action (VLA) models, large‑scale generalist models, generative AI, and related methods, we can leverage this data to significantly enhance robot autonomy, navigation, and manipulation skills. In this role you will develop multi‑modal models that enable robots to autonomously generate actions from demonstrations, real‑time sensor data, and natural‑language commands. We seek an expert in VLA models, imitation learning, and generative AI techniques with deep knowledge of supervised and self‑supervised learning algorithms. If you are passionate about pushing the boundaries of AI, we invite you to shape the future of intelligent robotics.
What You’ll Be Doing
* Develop and implement Vision‑Language‑Action 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 for real‑world autonomy and navigation 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 simulated and real‑world data
* Optimize and distill networks for real‑time deployment on edge hardware (e.g., Nvidia Jetson Thor)
* Build, lead, and mentor a high‑performance software engineering team
* 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 You Must Have
* Master’s degree or higher in Engineering, Robotics, or Machine Learning
* Minimum three years of industry or research experience (PhD experience is a plus)
* Strong deep learning fundamentals including supervised, self‑supervised learning, Transformer‑based architectures, policy optimization algorithms, imitation learning, and generative AI techniques (including Diffusion Models)
* Proven experience developing Vision‑Language‑Action models or large‑scale generalist robot models (e.g., RT‑2, Octo)
* Robust background in robotics, including autonomy and navigation
* Experience deploying neural networks on hardware platforms
* Proficiency in prototyping algorithms and training deep neural networks in Python (PyTorch)
Bonus Points
* PhD in Robotics, Engineering, Computer Science, Machine Learning, or related field, or equivalent research experience
* Publications at top‑tier conferences
* Experience managing a software team
* Ability to write production‑level code in modern C++
We require in‑person presence in our office locations.
