Principal Hardware Design Engineer

Location : Dearborn, MI(On-site) Position Overview

We are seeking a Principal Hardware Design Engineer to lead the end-to-end electrical design and development of automotive Battery Management Systems (BMS). This role requires deep expertise in high-voltage systems, battery electronics, and safety-critical hardware design. The successful candidate will play a key leadership role in defining BMS architecture, guiding hardware development, and collaborating across global engineering teams to deliver robust, high-performance energy storage solutions.

Key Responsibilities Hardware Architecture & Design

• Lead the full lifecycle electrical design of automotive BMS hardware, including high-voltage monitoring, cell balancing, protection circuits, and communication interfaces (CAN, LIN, SPI, I C).
• Define and document BMS electrical architecture aligned with vehicle system requirements and functional safety goals.
• Develop detailed schematics, select components, and collaborate with PCB layout teams to ensure reliability, performance, and manufacturability.
• Design and integrate monitoring circuits and sensors to measure voltage, current, temperature, and state of charge (SOC).
  
  

Development & Validation

• Guide the development of BMS hardware components including PCBs, microcontrollers, analog/digital circuits, and sensors.
• Build, test, and validate hardware prototypes to ensure compliance with performance, safety, and regulatory requirements.
• Conduct hardware troubleshooting and root cause analysis, implementing design improvements to enhance system performance and robustness.
  
  

Safety, Compliance & Documentation

• Ensure hardware designs comply with applicable safety standards such as ISO 26262, IEC 62133, and relevant federal and state regulations.
• Perform safety analysis and support DFMEA, WCCA, and design reviews.
• Create and maintain comprehensive design documentation including specifications, test plans, test reports, and engineering change records.
  
  

Collaboration & Leadership

• Work closely with internal and external stakeholders to define system and performance requirements.
• Collaborate with software, systems, validation, and manufacturing teams to ensure seamless BMS integration.
• Lead technical design reviews and provide mentorship to junior engineers.
• Coordinate and provide technical oversight for offshore and global engineering teams.
  
  

Continuous Improvement

• Stay current with emerging technologies, battery trends, and industry best practices.
• Drive continuous improvement initiatives to enhance BMS hardware design, efficiency, and reliability.
  
  

Required Qualifications

• Bachelor's degree in Electrical Engineering, Electronics Engineering, or related field (Master's preferred).
• Strong experience in automotive hardware design, with a focus on BMS or power electronics.
• Proficiency with PCB design tools (Altium Designer, Cadence) and simulation tools (SPICE).
• Strong knowledge of analog and digital circuit design, microcontrollers, and sensor integration.
• Experience with Li-Ion battery systems, battery safety, and industry standards.
• Excellent analytical, troubleshooting, and problem-solving skills.
• Proven leadership experience managing and guiding engineering teams.
