We are seeking a Senior Power Module Design Engineer to own the end-to-end electrical design of high-density power modules. These products target next-generation GPU and AI accelerator core power delivery with extremely high current density, fast transient response, and tight thermal and reliability margins. This is a hands-on design role with full ownership from architecture definition through module validation.

Responsibilities

Design high-current, high-density power modules for CPU/GPU/xPU core power and AI server power delivery applications.; Collaborate with package engineers and IC designers to develop advanced packaging solutions that integrate ICs, inductors, and capacitors into a high-density module.; Conduct PDN extraction for the module package to assess power path losses and switch-node ringing.; Design inductors per module and silicon pinmap. Work with inductor vendors to bring concept designs into real products.; Build and run module thermal models to ensure all components remain below maximum operating temperatures.; Work with the validation team to debug power modules and perform bench characterization, including efficiency, thermal, and transient performance.; Support design-for-manufacturing (DFM) and design-for-test (DFT) activities.

Requirements

BSEE or MSEE with 5+ years of hands-on power electronics design experience.; Strong experience designing high-current, high-frequency DC-DC converters, especially multiphase buck architectures.; Direct experience designing power modules, VRMs, or highly integrated power solutions is strongly preferred.; Deep understanding of power stage design and magnetics for high-current applications.; Hands-on experience in PCB layout for high-current-density and high-frequency applications.; Proficiency with design and simulation tools:; PCB layout: Cadence/Altium Designer; Circuit simulation: SIMPLIS / SIMetrix; PDN extraction and magnetic design: Q3D / PowerSI / Maxwell; Thermal simulation: Flotherm / Icepak; Proven ability to debug complex power circuits through lab measurement and root-cause analysis.; Ability to collaborate effectively across IC design, packaging, reliability, and manufacturing teams.
