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.

Responsibilities

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

Qualifications

PhD degree (or Master's degree with 3 years' experience) in Electrical Engineering, electrical simulation, or Physics with e-simulation

Experience and skills in electrical modeling and simulation at the power module, package, and system level

Understanding of power semiconductor devices (SiC, GaN, silicon), switching dynamics, and power loss mechanisms

Knowledge and experience of CAD concepts and SolidWorks

Familiarity with semiconductor packaging, power module, and system integration

Familiarity with material electrical properties

Strong knowledge of problem analysis and diagnosis techniques

Familiarity with package test and analysis, quality assurance, and reliability methods

Ability to perform model correlation to empirical measurement

Familiarity with the Unix/Linux operating system

Familiarity with FEA software ANSYS HFSS, SIwave, Q3D, Maxwell, and ANSYS Electronics Desktop

Strong English communication capability

Strong learning capability
