Hourly Pay Rate: $102.50-$112.90r
This is Remote or Hybrid (3 days in office) and 6 months Temp/contract role
Principal engineer shall develop a digital twin environment for our client's Robotics and Enabling Technology applications. The work includes migration of the current Mako OR simulator to NVIDIA Isaac Sim and expansion of the environment to support OR layout optimization, robotic system simulation, sensor simulation, and future AI model development for intra-operative use cases. The consultant will work closely with clinical application, robotics, and software engineering teams to establish a representative simulation environment of the Mako robotic system and related OR components, and to build a technical foundation for simulation-based evaluation, workflow studies, and AI model training.
Responsibilities include:
- Migrate the assets from the existing OR simulator to Isaac Sim using its import and scene definition capabilities, including the robot, the operating table, sawbone and tracking instrument models.
- Set up an articulation controller to control joint positions of the robot. Connect the simulation to ROS2 to use already existing functionality for controlling the robot.
- Evaluate the use of Isaac Sim for OR layout optimization and implement or extend missing features needed to support basic layout, access, collision, and workflow studies.
- Develop a physics model for tool-tissue interaction to accurately model bone resection and tissue manipulation.
- Integrate a variety of sensor models into the simulation.
Desired qualifications:
- Solid background with python programming in a Linux environment.
- Experience with robotics hardware development and CAD modeling.
- Exposure to simulation tools (e.g., Gazebo, Webots, Unity, MATLAB/Simulink, NVIDIA Isaac Sim).
- Experience with physics modeling and simulation.
- Experience with Omniverse and USD workflows preferred.
- Experience with articulated robot simulation preferred.
- Experience with edge computing preferred.
- Robotics controls background and working knowledge of ROS2 preferred.
