About The Position

Vertical Semiconductor, a venture-backed MIT spin-out, is leading the development of vertical gallium nitride (GaN) power electronics to build the foundational power layer for the next generation of compute and AI. The engineering team works across the full lifecycle of our vertical GaN power devices, from architecture and process integration through modeling, characterization, and reliability. This posting is for engineers with a background in wide-bandgap (WBG) power semiconductors, including GaN, SiC, or related technologies, at any career stage. Where you spend most of your time will depend on your background and where the team needs help most. This could mean device modeling and simulation, on-wafer characterization, process integration, or failure analysis and reliability work. If you have hands-on experience with wide-bandgap power devices and want to build a new device technology from the ground up, we want to hear from you.

Requirements

B.S., M.S., or PhD in Electrical Engineering, Physics, Materials Science, or a related field
Experience with GaN, SiC, or other wide-bandgap semiconductors, ideally in power device applications
Hands-on experience in at least one of: device characterization, process integration, or device modeling and simulation
Comfortable working with data analysis tools such as Python or MATLAB
Strong communication skills and the ability to work across disciplines

Responsibilities

Support device architecture, process integration, and technology development for our vertical GaN power devices
Run device modeling and simulation to inform design and process decisions
Perform on-wafer and discrete device characterization, including DC, CV, and dynamic testing
Support failure analysis and reliability investigations for wide-bandgap power devices
Develop and review GDS layouts and test structures to support device learning and validation
Collaborate with epitaxy, process, packaging, and reliability teams on cross-functional device work
Build and run application evaluation boards to connect device behavior to system-level performance
Keep clear records of experiments, test data, and process learnings
