Job Description
Principal Hardware Design Engineer
Location: Detroit, MI
Responsibilities
- Lead the end-to-end electrical design of automotive BMS, including high-voltage monitoring, cell balancing, protection circuits, and communication interfaces (CAN, LIN, SPI, etc.).
- Define and document the BMS electrical architecture in alignment with vehicle system requirements and safety goals.
- Work with both internal and external customers on defining system and performance requirements.
- Perform and guide the hardware components development of the Battery Management System (BMS), including printed circuit boards (PCBs), microcontrollers, analog and digital circuits, and sensors.
- Create detailed schematics, evaluate component selection, and collaborate with PCB layout designers to ensure the reliability and functionality of the BMS hardware.
- Build and test hardware prototypes, ensuring they meet performance and safety specifications and make design improvements as needed.
- Develop and integrate monitoring circuits and sensors to measure key battery parameters such as voltage, current, temperature, and state of charge.
- Ensure the hardware design adheres to relevant safety standards, such as ISO 26262 or IEC 62133, and conduct safety analysis.
- Work closely with cross-functional teams, including software engineers, system engineers, and testing teams, to integrate the BMS into the overall energy storage system.
- Create comprehensive design documentation, including specifications, test plans, DFMEA, WCCA and test reports.
- Troubleshoot and resolve hardware-related issues, making improvements to enhance BMS performance.
- Stay up-to-date with emerging technologies, industry trends, and best practices to continually improve the BMS hardware design.
- Adhere to federal and state regulations.
- Adhere to all company policies, processes, and procedures.
- Performs other duties as requested, directed, or assigned.
- Predictable and reliable attendance.
- Product experience with Li-Ion batteries, battery pack design, electric vehicles, power systems, alternative energy systems, electronic control units (ECUs), MEMS, and sensors preferred.
- Proficiency in PCB design tools (e.g., Altium Designer, Cadence) and simulation tools (e.g., SPICE).
- Strong knowledge of analog and digital circuit design, microcontrollers, and sensor integration.
- Experience with battery technologies, battery safety, and relevant industry standards.
- Excellent problem-solving skills and the ability to work in a collaborative team environment.
- Knowledge of programming languages (e.g., C/C++) is a plus.
- Proven ability to analyze electrical issues and find solutions.
- Demonstrated leadership skills necessary to manage and develop a team through assignments.
- Proven track record in leading design teams, conducting technical reviews, and resolving cross discipline engineering challenges.
Prior success in collaborating with offshore or global teams, including technical oversight and task coordination
