the lottery is wage-weighted — each level is one more entry
$19,530 more — $189,530 — moves this role to Level IV and 4 lottery entries. That figure is inside the range the employer already advertised.
Based on the DOL prevailing wage for this occupation and worksite, a base salary of $189,530 would place this position at wage Level IV. That figure is within the posted range, and I'd like to target it. This role classifies under "Mechanical Engineers" for prevailing-wage purposes.

About the role
- We are seeking a Simulation Integration Engineer to be the critical technical link between these two teams.
- This is a "Sim-to-Stack" orchestration role.
- While you won't be deploying to physical hardware, you are responsible for ensuring the virtual world provides high-fidelity data to the
Responsibilities
- ROS2 Stack Integration: Develop and maintain the ROS2 middleware layers (C++/Python) that allow AI models to receive sensor data and send control commands within the simulation.
- Scenario Engineering: Script and implement dynamic testing scenarios (e.g., traffic interactions, pedestrian behavior, triggered events) using Python or simulator-specific APIs.
- Bridge Development: Collaborate with our Senior Full-Stack Engineer to ensure simulation states and "Success/Failure" metrics are correctly streamed to our web-based dashboard.
- Data Logging: Manage the serialization of ROS2 messages (MCAP/Bag files) for post-simulation analysis and playback.
- Scenario Logic: Experience building event-driven logic and "adversarial" agent behaviors within a simulated environment.

Requirements
- Expertise in ROS2: Mastery of ROS2 (Humble, Foxy, or Jazzy), including node composition, custom message types, and QoS configuration.
- Programming: High proficiency in Python 3.x (for scenario logic) and Modern C++ (for performance-critical nodes).
- Simulation Platforms: Proven experience with at least one major simulator (e.g., CARLA, Gazebo, NVIDIA Isaac Sim, or SVL).
- Linux & Docker: Strong experience in Ubuntu-based development and containerizing robotics stacks for deployment.
- Systems Thinking: Ability to debug complex timing and synchronization issues between a simulator and a distributed ROS2 stack.
- Your role is to ensure that the autonomy stack runs reliably within a virtual environment, creating the complex testing scenarios and ROS2 infrastructure required to stress-test our AI models.
Nice to have
- Experience with automated testing frameworks for robotics.
- Understanding of coordinate frames (TF2) and spatial transformations.
- Knowledge of CI/CD pipelines for automated simulation runs.
