Awesome Motive
Company Description
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.
Role Description Vertical Semiconductor is seeking a Principal Device Engineer to serve as a senior technical authority in the development and commercialization of our vertical GaN power device technology. This is a hands‑on role intended for an engineer with around 20 years of semiconductor R&D experience who can operate at the intersection of device physics, process integration, and manufacturability.
In this role, you will provide deep technical leadership across device architecture, process development, modeling, and characterization, while working closely with cross‑functional partners in epitaxy, process engineering, packaging, reliability, and systems. You will play a critical role in defining device roadmaps, de‑risking technology transitions, and guiding decisions that directly impact product performance and scalability.
This position offers the opportunity to help shape a world‑changing power electronics platform at a pivotal stage, with direct influence on the company’s technical direction and long‑term success. We prefer candidates who can work from our office at Greentown Labs (Somerville, MA).
Key Responsibilities
Serve as a

to guide design optimization, scaling strategies, and reliability improvements
Plan and execute
device development programs
in shared fabs and external foundries, including technology transfer and process co‑development
Partner closely with internal and external teams on
CMOS‑compatible GaN process integration , yield learning, and manufacturability
Provide technical leadership in
failure analysis, reliability physics, and root‑cause investigations
for wide‑bandgap power devices
Oversee and interpret
on‑wafer and discrete device characterization , including DC, CV, dynamic, and high‑power testing
Develop and review
GDS layouts , test structures, and evaluation vehicles to support device learning and validation
Support system‑level understanding through
application evaluation boards , measurements, and correlation to device behavior
Mentor junior engineers and influence technical best practices through
informal technical leadership , design reviews, and knowledge sharing
Contribute to IP development, publications, and external technical engagements as appropriate
Qualifications
PhD or equivalent industry experience in
Electrical Engineering, Physics, Materials Science, or Device Engineering
Approximately
15–25 years of professional R&D experience
in semiconductor device development

power device design
in GaN and/or SiC, including vertical device concepts
In‑depth understanding of
semiconductor manufacturing processes , integration challenges, and yield considerations
Proven experience working in
shared fab and foundry environments , including external technology transfers
Strong proficiency in
TCAD simulation
for device physics, scaling, and optimization
Advanced data analysis skills using
Python, MATLAB, or equivalent tools
Hands‑on experience with
GDS layout
and test structure design
Expertise in
wide‑bandgap power device failure analysis and reliability physics
Experience with
on‑wafer automated DC/CV/dynamic testing
and discrete component characterization
Ability to perform
analytical calculations, simulations, design, build, and measure
application evaluation boards as needed
Excellent communication skills with the ability to collaborate effectively across disciplines and with external partners
Values & Culture Fit Vertical Semiconductor is seeking an engineer who is not only capable of accelerating the technical vision of the company but is also willing to get involved in the day‑to‑day execution of a startup. The ideal candidate is someone who enjoys tackling complex engineering challenges, is comfortable with a hands‑on approach in a collaborative arena and thrives in a startup environment where they can make an immediate impact. We value integrity, initiative, problem‑solving, creativity and a passion for creating transformative technology that can change industries and improve the world.
Compensation We offer a competitive salary and comprehensive benefits package with participation in our stock option program that is commensurable with candidates’ experience and impact.
