Controls Simulation Engineer

Responsibilities

• Design, architect, and own the end-to-end software-in-the-loop (SIL) simulation and test framework.
• Develop message replay capabilities to feed trackfiles and site-server messages into control modules at realistic rates.
• Build scenario authoring and regression infrastructure to automate the detection of control-software failures.
• Develop a Flutter-based visualization and operator UI to monitor module inputs, outputs, and vehicle positions.
• Implement version comparison tools to allow teams to qualify changes and catch regressions across software releases.
• Partner with controls, motor-control, and embedded software teams to ensure the tool meets user needs.

Requirements

• Bachelor's degree in Software Engineering, Computer Science, Electrical Engineering, Mechanical Engineering, Controls, or a related field.
• 2–5 years of experience building simulation, test-infrastructure, or engineering-tooling software.
• Proficiency in Python and/or C++ with the ability to design maintainable applications.
• Experience with containerization and reproducible environments using Docker.
• Experience with message-based systems such as protobuf or similar serialized formats.
• Experience in UI development using a modern framework.
• A working understanding of control systems and closed-loop logic.
• Ability to work on-site in St. Louis, MO.
• Fluency in written and verbal English.

Preferred Qualifications

• Hands-on experience with MATLAB/Simulink for modeling dynamic systems.
• Experience with Flutter or Dart.
• Domain familiarity with rail-signaling (ATP, braking curves) or motor-control (inverters, electric drives).
• Knowledge of vehicle dynamics or drivetrain modeling.
• Experience with fault-injection or transitioning from SIL to Hardware-in-the-Loop (HIL).
• Familiarity with CAN bus and vehicle log formats.

Benefits

• 100% employer-paid medical premiums.
• Low-cost dental and vision options.
• Unlimited paid time off (PTO).
• Company equity.
• Paid parental leave.
