You will create functional requirements, design interfaces, and develop embedded control algorithms using

Qualifications

• Bachelor's or advanced degree in Engineering
• Minimum 5 years of engineering experience, preferably in automotive, commercial, or heavy-duty vehicle design
• Proficiency in MATLAB, Simulink, and Stateflow
• Experience integrating controls systems with low and high voltage automotive hardware, such as DC-DC converters, motors, inverters, Li-ion batteries, and high-power chargers
• Strong, hands‑on experience in troubleshooting, product assembly, prototyping, testing, and validation at both onsite and remote locations

Responsibilities

• Create functional requirements for vehicle behavior to ensure compliance with program requirements and standards. Define communication interfaces and protocols for all vehicle systems
• Develop, test, and validate control algorithms to improve both existing and future bus capabilities. Design and implement customized algorithms for embedded controllers to optimize vehicle performance, drawing on foundational knowledge of EV specific architecture, components, and standards
• Construct and modify codes/models using tools such as Simulink, MATLAB, and structured text for real-time embedded targets
• Participate in DFMEA, hazard, and risk assessments to enhance fault detection and minimize potential failures
• Create environments to design, test, and refine electronic control systems prior to their integration on a vehicle
• Actively contribute to software-specific design test plans. Perform hands‑on troubleshooting, testing, and validation activities both onsite and in the field. Collaborate with engineers to bring up prototype buses and address issues effectively
• Lead the development of advanced diagnostics and create detailed troubleshooting guides to support efficient issue identification and resolution. Provide technical input to generate bus manuals, ensuring accuracy and completeness
• Architect and maintain control development processes, including version control, automated code review, and regression testing. Familiarity with typical development operations (DevOps) such as automated unit testing through CI/CD Git functionality is a plus
• Release software through the Product Lifecycle Management (PLM) system while maintaining traceability throughout the entire bus lifecycle
• Lead continuous improvement efforts for control systems to enhance vehicle reliability, performance, and customer satisfaction. Analyze field data and feedback to identify areas for improvement
