Robotics Simulation Engineer: NVIDIA Isaac & AWS

Protingent; Bellevue (WA); On-site; USD 96,000 - 158,000; Full time

Job summary

Protingent Staffing seeks a Simulation Engineer in Bellevue, WA for a contract role. You will build and scale a simulation engine on NVIDIA Isaac Sim, integrate with the full production software stack, and develop sensor models for cameras, LiDAR, and IMU.

Large-scale AWS pipelines will run thousands of scenarios in parallel to maximize regression coverage. You will own evaluation pipelines, optimize performance, and ensure sim-to-real transfer of behaviors learned in simulation.

Qualifications

• 3+ years of software engineering experience (SDE II) or 5+ years (SDE III).
• Proficiency in Python and/or C++.
• Hands-on experience with NVIDIA Isaac Sim, Isaac Lab, or comparable robotics simulation frameworks.
• Strong working knowledge of ROS2 - robot message types, transforms (TF2), sensor topics, and launch systems.
• Experience building and operating distributed pipelines at scale on AWS (EC2, Batch, S3) - running thousands of parallel jobs.
• Experience integrating simulation or test frameworks into CI/CD pipelines.
• Strong understanding of physics simulation, sensor modelling, and robotics fundamentals.
• Experience with performance profiling and optimization - GPU utilization, memory, and throughput benchmarking.
• Experience with containerization (Docker) for reproducible simulation environments.

Responsibilities

• Build and scale the simulation engine on top of NVIDIA Isaac Sim - integrating the robot's full production software stack with no code changes between simulation and real-world deployment.
• Develop sensor simulation models (cameras, LiDAR, IMU) that match real-world noise profiles, latency, and field-of-view specifications.
• Build large-scale scenario execution pipelines on AWS (EC2, Batch, S3) - running thousands of scenarios in parallel to maximize regression coverage.
• Own evaluation pipelines that capture sensor and mission data, compute automated metrics (trajectory accuracy, collision detection, ODD validation, success/failure rates), and integrate into CI/CD.
• Improve simulator performance and real-time factor - ensuring simulation runs faster than real-time without trading accuracy.
• Work with robot software, autonomy, and science teams to validate that behavior learned in simulation transfers directly to the real world.
• Diagnose and close sim-to-real gaps in physics, sensor fidelity, and robot behavior.
