Senior Controls Engineer

About the role

Parallel Systems is pioneering autonomous battery-electric rail vehicles designed to transform freight transportation by shifting portions of the $900 billion U.S. trucking industry onto rail. Our innovative technology offers cleaner, safer, and more efficient logistics solutions. Join our dynamic team and help shape a smarter, greener future for global freight.

Senior Controls Engineer

Parallel is seeking a Senior Controls Engineer with deep expertise in control systems development to join our engineering team. This role focuses on modeling, simulating, and designing the software that controls the electrical and mechanical systems on our rail vehicles, and on proving that software out in simulation before it reaches hardware. The ideal candidate has a strong foundation in control systems theory, extensive experience using simulation to develop and verify controllers, and a proven track record of delivering high-quality, real-time control software.

Responsibilities

- Develop and maintain plant models of vehicle dynamics, powertrain, and braking systems, and use them to analyze, simulate, and tune controllers in tools such as MATLAB/Simulink or Python

- Design and implement control algorithms for vehicle systems, validating them in simulation before deployment to embedded targets

- Build and own simulation infrastructure, including model-in-the-loop (MIL), hardware-out-of-the-loop (HOOTL) and hardware-in-the-loop (HITL) environments, used to verify control software ahead of vehicle testing

- Use modeling and simulation to derive sensor and actuator requirements that meet system performance needs

- Correlate simulation results against test and field data to validate and improve model fidelity

- Support system integration and vehicle testing, using simulation to reproduce and debug issues observed on hardware

- Ensure high reliability, safety, and performance in all control software implementations

What Success Looks Like

- In 30 days: You have defined requirements and an architecture for the platooning simulation suite. You have run the existing code and have developed a feature roadmap to achieve the analysis goals required for the project

- In 60 days: You have implemented the simulation MVP and are running real test cases. You have evaluated the baseline assumptions of our platooning model and have identified improvements to the controls stack to achieve better performance.

- In 90 days: You have used the HOOTL simulation to drive performance upgrades in the controls stack and have implemented the onboard features required for real-world testing. You are running a test campaign using real Parallel vehicles to validate the outputs of the model and ground our software stack

Basic Qualification

- Bachelor’s or Master’s degree in Electrical Engineering, Mechanical Engineering, Software Engineering, Mathematics, or a related field
