Principal System and Electrical Engineer

Location: Foster City, CA Duration: Full-Time or Contract

Note: Candidates must have experience integrating SAE automotive systems into Siemens Capital tool workflows.

We are seeking a Principal System and Electrical Engineer to lead system-level electrical architecture design and validation for cutting-edge automotive platforms. This role requires strong collaboration across systems, validation, and offshore teams, using tools like Siemens Capital to build traceable, efficient, and compliant architectures.

• Develop comprehensive electrical architectures using Siemens Capital and related tools.

• Define ECU signal interfaces, network topologies (HV and LV), and integration strategies based on vehicle requirements.

• Validate BMS, high-voltage distribution (e.g., HV-BJB), and safety-critical design components.

• Mentor offshore teams (India/Mexico) on harness design, signal integrity, and embedded validation.

• Apply DFMEA and FTA methodologies to mitigate design risks and failure modes.

• Support Digital Twin environments through schematics, harness topology design, and PCB modeling.

• Troubleshoot system-level issues involving electrical and software interfaces (e.g., CAN, UART, SPI).

• Lead design reviews and document validation outcomes, influencing architecture through real-world implementation insights.

• Electrical domain models and schematics using Siemens Capital

• Interface validation reports for CAN, J1772, and ARM Cortex-M7

• DFMEA and FTA reports for HV/LV circuits

• Documentation from mentoring offshore integration teams

• Integration-ready PCB assets aligned with UL and vehicle safety standards

• 5+ years in electrical integration, specifically in BMS, power management, and EV charging (J1772, J3068)

• Proficiency in Siemens Capital, Altium Designer, and system validation in 400V 480V environments

• Experience with cross-functional engineering teams (software, mechanical, harness)

• Deep understanding of DFMEA, HDI PCB design, and UL compliance for EV systems

• Leadership in mentoring and cross-disciplinary collaboration
