Senior Director of Power Systems Engineering

Wolfspeed • Santa Barbara, CA

8d • $297,000 - $408,000 • Onsite

About The Position

This 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 Packaging.

Requirements

• Master’s or PhD degree in Electrical Engineering with a power electronics specialization.
• 5+ years in high-power switch-mode power supply (SMPS) design or grid-tied conversion.
• 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.
• Proven experience programming microcontrollers for power electronics (e.g., TI C2000, STM32, or FPGA).
• Expert utilization of PLECS, Simplis, MATLAB/Simulink or LTspice for system-level analysis of the AC/DC and DC/DC converters.
• Knowledge of 48V and 800V/±400V DC bus distribution frameworks common in hyperscale environments.
• Familiarity with OCP (Open Compute Project) power specifications and 80 Plus Titanium efficiency requirements.

Responsibilities

• Architect and build AC/DC front-ends and DC/DC converters handling kilowatt to hundreds of kW power blocks.
• 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 delivery.
• Component selection, thermal-conscious schematic capture, and multi-layer PCB layout optimization.
• Interaction with applications engineering for debug, simulation and validation of converter specs.
• 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.
• Develop, code, and tune digital control loops for real-time power conversion and telemetry.
• Direct EMI/EMC mitigation strategies and validate systems against grid and safety standards.

Benefits

• Wolfspeed is an equal opportunity employer. We recruit, employ, train, compensate and promote regardless of race, sex, religion, color, national origin, disability, age, veteran status, gender identity, sexual orientation and other protected status as required by law.
• We are an equal opportunity employer and all qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, national origin, disability status, protected veteran status, or any other characteristic protected by law.
