As a Senior Power System Engineer on the LPU team, you will lead the development of efficient, high-current power systems for advanced AI accelerators and data centers. Your expertise in power electronics and control theory will be crucial in architecting power delivery systems for data center and super compute platforms, including multiphase VRMs and Intermediate Bus Converters (IBCs). You will also work with cross-functional teams to ensure power integrity across high-density PCB builds.
Responsibilities:
- Architect power delivery systems for data center and super compute platforms, including multiphase VRMs and Intermediate Bus Converters (IBCs).
- Architect low voltage, high current (500A-1000A+) power rails for LPU, GPU and accelerator modules.
- Apply control theory principles to optimize power converter performance, stability, and transient response.
- Select and characterize power components including MOSFETs, inductors, transformers, and magnetic devices using vendor tools and configuration GUIs.
- Collaborate with ASIC and package teams to ensure power integrity across high-density PCB builds.
- Develop and complete lab validation plans using oscilloscopes and other test equipment.
- Build automation scripts to improve characterization efficiency and data analysis.
- Collaborate with power management ICs via I2C, SPI, and PCIe protocols for system integration and debug.
- Work with cross-functional teams including mechanical, thermal, firmware, and silicon build engineers.
Requirements:
- BS or MS in Electrical Engineering (or equivalent experience) with focus on power electronics.
- 5+ years of experience crafting power systems for data center, super compute, or high-performance computing applications.
- Deep expertise in multiphase VRM development and Intermediate Bus Converter (IBC) topologies, and control theory as applied to power converters.
- Hands-on experience with high-current (500A-1000A+) low voltage power delivery systems.
- Proficiency with Cadence tools for power integrity analysis and simulations, and experience with high-density PCB build and layout considerations.
- Familiarity with communication interfaces: I2C, SPI, PCIe.
- Proficient with scripting languages (Python, Perl) and Linux environment.
- Strong hands-on lab skills with oscilloscopes and power measurement equipment.
- Clear and effective communication skills, both written and verbal.
Preferred Qualifications:
- Experience with AI accelerator power delivery for platforms such as TPU, GPU, or similar architectures.
- Knowledge of advanced magnetic component build and optimization for high-density applications.
- Experience with power modeling and simulation tools.
- Background in EMI/EMC compliance and mitigation techniques.
- Proven track record in bringing power solutions from concept to mass production with experience collaborating with external vendors and suppliers.
