Jobs at Vertical Semiconductor

Develop and support customer designs using vertical GaN power devices. Responsibilities include power converter simulations, evaluation board and reference design development, high-voltage wide-bandgap device characterization, bench testing, troubleshooting, technical documentation, and customer engagement. The role requires hands-on power electronics experience, SPICE or PLECS proficiency, PCB design familiarity, and strong technical communication.

Work across the full device lifecycle for vertical GaN power devices: architecture, process integration, modeling/simulation, on-wafer and discrete characterization (DC, CV, dynamic), failure analysis, reliability, GDS layout/test structures, and cross-functional collaboration to connect device behavior to system performance.

The Principal Applications Engineer will lead customer technical engagement, develop simulation models, evaluate power converters, and create technical content for Vertical GaN devices.

The Principal Semiconductor Device Engineer leads the development of vertical GaN power devices, focusing on architecture, process integration, modeling, and failure analysis while mentoring junior engineers and collaborating across functions.

Characterize vertical GaN devices on-wafer and in-package using high-voltage instrumentation; design PCB test boards for switching and UIS tests; run JEDEC-style reliability qualifications; automate measurements and analyze data with Python/MATLAB; extract device parameters for datasheets; collaborate cross-functionally to support commercialization.
