Robotics Simulation Engineer

About the role

We're looking for a Simulation Engineer to own and expand our NVIDIA Isaac Sim and Omniverse simulation infrastructure. You'll build the digital twin environments, sim assets, and CI/CD pipelines that our autonomy team relies on daily.

Responsibilities

• Build, maintain, and extend simulation environments in NVIDIA Isaac Sim and Omniverse for humanoid robot development.
• Develop and manage OpenUSD sim assets: robot models, tools, workpieces, customer facility environments (shipyards, steel fabrication plants, industrial sites).
• Create and maintain physics-accurate digital twins of customer facilities (shipyards and industrial manufacturing) for behavior validation and deployment planning.
• Integrate all autonomy subsystems (locomotion, manipulation, perception, hands, navigation, welding) to run against Isaac Sim.
• Design and implement behavior-level CI/CD pipelines that automatically validate robot behaviors in simulation.
• Prototype and mock-test robot behaviors (welding, navigation, manipulation) in simulation before hardware integration.
• Develop synthetic data generation pipelines for training perception, manipulation, and navigation models.

Requirements

• BS, MS, or PhD in Robotics, Computer Science, Mechanical Engineering, or a related field.
• 3+ years of professional experience in robotics simulation, digital twin development, or physics-based simulation environments.
• Strong hands-on experience with NVIDIA Isaac Sim and/or NVIDIA Omniverse.
• Working knowledge of OpenUSD (Universal Scene Description): authoring, composition, referencing, flattening, and debugging USD stage hierarchies.
• Proficiency in Python; comfortable writing simulation tooling, test harnesses, and automation scripts.
• Experience with at least one physics engine: PhysX, MuJoCo, Bullet, or Drake.
• Solid understanding of robot kinematics, dynamics, and articulated body simulation.
• Experience developing or maintaining CI/CD pipelines for simulation or robotics software.
• Familiarity with containerization (Docker) and DevOps practices for simulation infrastructure.
• Ability to create and manage 3D simulation assets (meshes, materials, collision geometry, articulation definitions).

Qualifications

• Experience with NVIDIA Isaac Lab for reinforcement learning environment setup and training.
• Familiarity with NVIDIA Cosmos for synthetic data generation and scene variability.
• Experience with ROS/ROS 2 and Gazebo simulation.
• Experience with Unreal Engine or other real-time rendering engines for robotics visualization.
• Background in manipulation simulation: contact modeling, grasp planning, dexterous multi-fingered hand interaction, and force/torque estimation.
• Experience with motion capture data pipelines and motion retargeting to robot models.
• Experience with behavior trees, task planning, or autonomy stack architecture.
• Knowledge of Omniverse extensions development and Kit SDK.
