Assistant Research Scientist; PREP

PREP Research Associate

This position is part of the National Institute of Standards (NIST) Professional Research Experience (PREP) program. NIST recognizes that its research staff may wish to collaborate with researchers at academic institutions on specific projects of mutual interest, thus requires that such institutions must be the recipient of a PREP award. The PREP program requires staff from a wide range of backgrounds to work on scientific research in many areas.

Employees in this position will perform technical work that underpins the scientific research of the collaboration.

The work will entail: NIST is investigating the performance of commercial and custom AI systems (hardware and software) for Physical AI applications, specifically in machine learning, reinforcement learning, and foundation model training for Vision-Language Models (VLMs) and Vision-Language Action (VLA) architectures. The work will focus on leveraging physics-based simulations (e.g., Gazebo, Mu Jo Co , Drake) and synthetic data generation within platforms like NVIDIA Isaac Sim / GR00T / Cosmos to conduct experiments, analyze system capabilities, and generate high-quality data to train robust Physical AI systems.

• Develop Physical AI applications using machine learning and reinforcement learning.
• Research and develop Foundational model training for Vision-Language Models (VLMs) and Vision-Language Action (VLA) architectures.
• Research and develop methods for synthetic data generation within platforms like NVIDIA Isaac Sim / GR00T / Cosmos to conduct experiments to analyze system capabilities, and generate high-quality data to train robust Physical AI Systems.
• Write reports and develop weekly presentations to explain the progress of the project.
• Work Schedule:
  
  On-campus (Gaithersburg, MD), Full-Time (40 hrs / week).

• US Citizen Preferred.
• Education:
  
  Engineering / Computer Science majors with Master's Degree or Ph.D, or in the final year of degree (e.g., Computer Science, Robotics, Mechanical Engineering or similar).
• Strong programming experience in Python and C++.
• Experience in AI / Machine Learning frameworks (e.g., Tensor Flow, PyTorch, etc.).
• Experience with developing and applying tools for Machine Learning, Reinforcement Learning, and Foundational Models for Vision-Language Models (VLM) and Vision-Language Action (VLA) architectures.
• Experience in Synthetic data generation in and for NVIDIA Isaac Sim, GR00T, and Cosmos environments.
• Experience in Physics-based simulation engines (e.g., Gazebo, Mu Jo Co , Drake, etc.).
• Experience with version control software and workflow (e.g., Git, Git Hub, Git Lab, Bit Bucket, etc).
• Experience with Unix / Linux Operating systems.
• Experience with ROS 2 on Linux systems.
• Some experience in with CAD software (e.g., Solid Works, OnShape, etc.).

The referenced salary range represents the minimum and maximum salaries for this position and is based on Johns Hopkins University's good faith belief at the time of posting. Not all candidates will be eligible for the upper end of the salary range. The actual compensation offered to the selected candidate may vary and will ultimately depend on multiple factors, which may include the successful candidate's geographic location, skills, work experience, internal equity, market conditions, education/training and other factors, as reasonably determined by the University.
