Job summary

Bonsai Robotics in California is seeking a Senior Robotics Software Engineer, Simulation to own and advance our end-to-end simulation platform. You will model vehicles, sensors, and environments, and build the CI pipelines and metrics that tell us when a change is safe to ship, ensuring that what passes in simulation also works in the field.

You will integrate the simulator with ROS 2, develop SIL and HIL frameworks, reproduce field failures as regression scenarios, and generate synthetic data

Qualifications

• Experience building and maintaining robotics simulation platforms.
• Strong CS fundamentals and ROS 2 stack proficiency.
• Proven SIL/HIL and closed-loop evaluation experience.
• Proficiency in C/C++ and Python with large codebases.
• Experience with Isaac Sim, MuJoCo, Gazebo or similar.

Responsibilities

• Build and maintain simulation environments modeling field conditions.
• Own simulator-ROS 2 interface and SIL/HIL frameworks for full stack.
• Turn field logs into regression simulations and expand scenario library.
• Create sensor models (camera, GNSS/RTK, IMUs, LiDAR) and noise handling.
• Model vehicle dynamics and terrain interaction across robot forms.
• Automate scenario generation, metrics, and CI-tested changes.
• Keep simulation fast, deterministic, and predictive of real-world results.
• Generate synthetic data with ML team for domain randomization.
• Collaborate with perception, controls, and platform teams on sim requirements.
