Senior Principal Engineer

We are seeking a Power Design Engineer to lead the development of test vehicles supporting our high-current BCD (Bipolar-CMOS-DMOS) and low-voltage GaN power process and product portfolios. This role owns test vehicle definition, circuit and layout design, and characterization planning from concept through silicon bring-up, working closely with process development, product engineering, and applications teams. The ideal candidate has hands-on experience designing power devices and circuits at both the IC and module level, and is fluent in the power topologies these test vehicles are ultimately intended to support.

Key Responsibilities

• Define, design, and drive execution of test vehicles (TVs) for high-current BCD and LV GaN process technologies, including device test structures, scaled power stages, and full-function demonstration circuits.
• Translate process capability targets and product roadmap requirements into test vehicle architecture and specifications.
• Design and simulate power stage circuits (e.g., synchronous buck/boost, multiphase, half-bridge/DrMOS, gate drivers) used to validate device performance under realistic switching and thermal conditions.
• Select and characterize power devices (LDMOS, trench MOSFETs, LV GaN HEMTs, Schottky/sync rectifiers) for inclusion in test structures, working with device/process engineering on layout-dependent tradeoffs (RDS(ON), Qg, breakdown voltage, SOA).
• Perform IC-level layout and design for test structures, including parasitic-aware layout for switch nodes, current sensing, and gate drive paths.
• Extend designs to module/package level as needed — co-design of power stages with packaging, magnetics, and PCB layout for evaluation boards and system-level test vehicles.
• Develop test and characterization plans covering DC parametrics, switching performance, efficiency, transient response, and voltage/current stress margins (including switch-node ringing and abs-max validation).
• Lead or support silicon bring-up, debug, and correlation of measured results against simulation and design targets.
• Collaborate cross-functionally with process integration, reliability, product/applications engineering, and test engineering to close the loop from process split data to product-ready specifications.
• Document design methodology, test vehicle results, and characterization data to support technology qualification and product development decisions.
