• 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
