About The Role

onsemi is seeking a self-driven and motivated professional to join our Corporate Central Engineering modeling and simulation team, located in Scottsdale, AZ or San Jose, CA. As a Senior Power Module Electrical Simulation Engineer, you will support the development of next-generation power modules and power delivery solutions for AI data center applications — driving new package and system integration, new product design, assembly and process development, quality and reliability, and worldwide customer engagements. As AI compute pushes power demands to unprecedented current densities, you will help shape the power module architectures that make high-efficiency, high-reliability data center power delivery possible.

The successful candidate will have the opportunity to

Perform power module, package, and system-level integration electrical simulation for AI data center power delivery applications
Model electrical-thermal-mechanical interaction for next-generation breakthrough power modules, including SiC and GaN wide-bandgap devices, ISG chiplet, ASG, and 3D integration
Extract and analyze parasitic RLC (resistance, loop inductance, capacitance) of module layouts, busbars, interconnects, and packaging to minimize switching loss, overshoot, and EMI
Perform high-frequency simulation including S-parameter and power integrity/PDN analysis under fast AI compute load transients
Conduct electro-thermal co-simulation to predict junction temperatures, current sharing, and hotspots against reliability and derating targets
Analyze and correlate modeling results to measured data from power module hardware
Develop and maintain state-of-the-art system integration, electrical, and electro-thermal modeling methodologies to improve modeling efficiency and accuracy
Set up and maintain the HW/SW environment for electrical-thermal-mechanical modeling
Provide power module electrical modeling support to field, application, and customer teams
Drive innovation of new power module technology through simulation
Develop advanced simulation methodologies such as AI/machine learning algorithms, AI agents, digital twins, and probabilistic and optimization methods
