Controls Engineer, Vehicle Controls

The role

You will develop, validate, and debug control algorithms for medium-duty EV and hybrid platforms. This involves creating Simulink/Stateflow models, performing MIL testing, and debugging on real vehicles using CAN data.

What you will do

• Develop, maintain, and improve control algorithms in MATLAB, Simulink, and Stateflow.
• Write, review, and refine software requirements.
• Develop and execute model-in-the-loop (MIL) test cases and test harnesses.
• Develop and maintain CI pipelines that automate model checks, code generation, and regression testing.
• Generate production code from models and review generated C code.
• Develop and integrate OBD/UDS diagnostic functions.
• Calibrate, tune control parameters and debug control behavior on bench, HIL, and vehicle.
• Perform root-cause analysis on issues found in vehicle testing and customer fleets.
• Participate in hands-on vehicle testing at test sites and customer locations.
• Support model reviews, modeling guideline checks, and configuration management.

Required qualifications

• 2-5 years of experience developing automotive or vehicle control software using model-based design.
• Strong hands-on proficiency in MATLAB, Simulink, and Stateflow.
• Experience applying control theory techniques such as PID control, LQR/optimal control, and Kalman filtering/state estimation.
• Experience writing software requirements and developing and executing MIL test cases.
• Working knowledge of C.
• Experience with CAN communication and analyzing CAN logs using Vector tools.
• Experience calibrating control parameters on bench or vehicle.
• Solid understanding of control systems fundamentals and vehicle systems.
• Experience with version control (e.g., Git).
• Comfortable working hands-on with vehicles and safely around high-voltage systems.
• Valid driver's license.
• Bachelor's degree in Electrical, Mechanical, Computer, Mechatronics, or Controls Engineering, or equivalent practical experience.

Nice to have

• Experience with EV or hybrid vehicle supervisory controls, energy management, or powertrain controls.
• Experience with SAE J1939 and commercial vehicle networks.
• Experience with automotive diagnostics: OBD, UDS (ISO 14229), DTCs, DIDs, and diagnostic description formats using Vector CANdelaStudio.
• Familiarity with AUTOSAR and its toolchain.
• Experience with Embedded Coder, Simulink Test, Model Advisor, or Polyspace, and with SIL/HIL testing.
• Experience building CI pipelines for model-based development.
• Familiarity with EV charging standards (SAE J1772, CCS, ISO 15118).
• Familiarity with ISO 26262 functional safety and ASPICE.
• Experience with requirements management tools (e.g., Jama, Polarion, DOORS) and scripting for data analysis or test automation.
• Experience analyzing field or fleet data to resolve customer issues.

Benefits

• Comprehensive Health, Dental & Vision (HDV) – 100% employee covered
• Early-stage Stock Options
• Robust Retirement Savings (401k, HSA, FSA)
• Generous Paid Time Off (PTO) & Parental Leave
• Annual Vacation Bonus
• Wellness & Fertility Benefits
• Cell Phone Stipend
• Complimentary Meals & Stocked Kitchens
