Senior Power Design Engineer (Sunnyvale)

We are seeking a Senior Power Design Engineer to lead the design and development of high-performance power delivery systems for advanced electronics. The role involves designing efficient power architectures, optimizing power supply circuits, and ensuring system reliability across a range of complex hardware products. The ideal candidate will collaborate with cross-functional teams to deliver robust power solutions, drive innovation, and support our next-generation technology roadmap.

In-vehicle electronics is a fast-growing technology in the global automotive industry, featuring many cutting-edge technologies such as compute, body and zone controllers, multi-view cameras, Gig+Ethernet, PCIe, digital/analog interfaces, and more. We are looking for a creative and enthusiastic candidate to become part of a fast-moving team that wants to lead the future direction of the automotive industry.

The ECU hardware design teams mission is to ensure our products are designed to meet the growing needs of our customers while ensuring robust, well-designed hardware that meets GM specifications and testing requirements from early hardware through the production design. In this role, you will be responsible for leading product development and integration activities.

Responsibilities include utilizing engineering tools and processes to successfully develop components and systems for vehicle programs.

Responsibilities:

• Develop and design high-efficiency power delivery architectures, including DC-DC converters, switching regulators, and power distribution networks (PDNs).
• Ensure power supply designs meet performance, thermal, and cost targets for advanced hardware systems.
• Perform detailed power simulations, including load regulation, transient response, efficiency, and thermal performance using tools like SPICE, PLECS, or MATLAB.
• Analyze power integrity (PI) and optimize designs for stability and minimal electromagnetic interference (EMI).
• Select power components such as power MOSFETs, inductors, capacitors, and controllers based on system requirements and performance goals.
• Work with suppliers to source and evaluate new power components for improved efficiency and reliability.
• Build, test, and validate power delivery systems on prototypes, using lab equipment like oscilloscopes, power analyzers, and thermal cameras to ensure they meet design specifications.
• Diagnose and resolve power-related issues during design, testing, and production phases, addressing failures such as over-temperature, EMI, and voltage regulation faults.
• Create and maintain power design documentation, including guidelines, specifications, and test protocols.
