Job description

Senior Director of Power Systems EngineeringLocation: Santa Clara, CA (On-site / Lab-focused)Role OverviewThis hands-on role involves the design, implementation and validation of high-efficiency AC/DC and DC/DC converters for next-generation data center architectures working with a stellar team of systems and applications engineers. This position focuses on delivering high-power density solutions ranging from kilowatt (kW) rack-level systems to hundreds of kW cluster-level architectures. The ideal candidate will blend hardware topology design/architecture with advanced digital control implementation to power cutting-edge AI, GPU, and CPU hardware. This is a senior role with high visibility that involves extensive interaction with management and cross-functional teams, such as Device Engineering, System Applications, and PackagingCore ResponsibilitiesHigh-Power Design: Architect and build AC/DC front-ends and DC/DC converters handling kilowatt to hundreds of kW power blocks.Topology Innovation: Design high-efficiency, high-density topologies (e.g., interleaved PFC, LLC, dual active bridge, phase-shifted full bridge, ISoP converters) to meet the stringent and increasingly challenging specifications for next generation data center power deliveryHardware Development: Component selection, thermal-conscious schematic capture, and multi-layer PCB layout optimization. Interaction with applications engineering for debug, simulation and validation of converter specs.Custom Magnetics Engineering: Design and model both discrete and planar in-PCB magnetics for high-frequency operation. Partner with magnetics vendors to specify, iterate, and manufacture custom magnetic components.Digital Control Implementation: Develop, code, and tune digital control loops for real-time power conversion and telemetry.Compliance & Validation: Direct EMI/EMC mitigation strategies and validate systems against grid and safety standards.Required QualificationsEducation: Master’s or PhD degree in Electrical Engineering with a power electronics specialization.Experience: 5+ years in high-power switch-mode power supply (SMPS) design or grid-tied conversion.Semiconductor Expertise: Deep hands-on design experience using SiC (Silicon Carbide) and GaN (Gallium Nitride) wide-bandgap devices, and their corresponding gate-drivers, isolators and sensing circuits.Digital Control Platforms: Proven experience programming microcontrollers for power electronics (e.g., TI C2000, STM32, or FPGA).Simulation Tools: Expert utilization of PLECS, Simplis, MATLAB/Simulink or LTspice for system-level analysis of the AC/DC and DC/DC converters.Advanced Architecture: Knowledge of 48V and 800V/±400V DC bus distribution frameworks common in hyperscale environments.Standards: Familiarity with OCP (Open Compute Project) power specifications and 80 Plus Titanium efficiency requirements.This role may require additional duties and/or assignments as designated by management.The posted salary range is what Wolfspeed reasonably expects to pay for this position.
