Job Description

Job title: Principal System and Electrical Engineer

Location: Foster City, CA (Onsite-5 days)

Duration : Fulltime or Contract

Role Summary:

Leverage advanced electrical integration expertise to lead the definition and validation of system-level electrical architectures at Client. This role is central to translating domain-specific configurations into a robust architecture baseline, interfacing across system, validation, and offshore teams to ensure seamless collaboration and traceability.

Key Responsibilities:

• Drive the development of the complete electrical architecture using Siemens Capital and other modeling tools.

• Define ECU signal interfaces, high-voltage and low-voltage network topologies, and system integration patterns aligned to vehicle requirements.

• Utilize hands-on experience in BMS, HV distribution (e.g., HV-BJB), and safety-critical design for architecture validation.

• Bridge onshore and offshore collaboration by mentoring teams in India/Mexico on harness design, signal integrity, and embedded validation.

• Apply DFMEA and FTA principles during architectural reviews to proactively identify design risks and failure modes.

• Contribute to Digital Twin validation environments by preparing schematics, harness topologies, and PCB design insights for simulation fidelity.

• Act as a focal point for system-level debugging, particularly where electrical/software interfaces intersect (CAN, UART, SPI).

• Lead and document design reviews, present validation results, and influence architectural decisions based on real-world implementation constraints.

• Key Deliverables:

• Siemens Capital-based electrical domain models and network schematics.

• Signal flow and interface validation reports (covering CAN, J1772, S32 ARM Cortex-M7 interfaces).

• DFMEA and Fault Tree reports on system-level circuits (HV/LV).

• Collaborative feedback and mentoring documentation from offshore integration teams.

• Integration-ready PCB assets aligned to UL standards and vehicle safety requirements.

Qualifications and Match to Role:

• 5+ years of hands-on electrical integration across BMS, power management, and charging standards (J1772, J3068).

• Strong knowledge of Siemens Capital, Altium, and system validation in high-voltage (400V–480V) environments.

• Demonstrated ability to execute multi-disciplinary engineering in collaboration with software, mechanical, and harness teams.

• Expertise in DFMEA, HDI PCB, and UL compliance processes for EV platforms.

• Prior experience mentoring interns and leading cross-functional technical sessions, aligning well with leadership expectations in this role.
