fab2 is seeking a hands-on Device Engineer to join its Process Team. This role is crucial for in-house device development, bridging process development with electrical test. You will characterize semiconductor devices, design and automate test infrastructure, and extract electrical parameters to drive process improvements. The position requires a deep understanding of device physics, experience with CMOS modeling, and collaboration across process, test, and design teams. You will work across the full testing stack, from test structure design to data analysis, shaping our CMOS process validation.
About fab2
The fab2 team can build anything. We design all the hardware and software needed to make chips and we make the fabs, tools, and components ourselves.
We're looking for exceptional, hands-on people who can iterate to the limits of what's possible.
fab2 was founded by Sam Zeloof and Jim Keller. Sam is best known for making chips in his garage, and Jim has been a leader in the semiconductor industry for the past 40 years.
About the team
The Process Team sits at the heart of our in-house device development, driving the design of each new generation of tools. This is unlike any role at a traditional foundry—we simultaneously develop recipes, apply novel materials, test and characterize our chips, and troubleshoot tools.
About the role
As a Device Engineer at fab2, you’ll play a critical role in bridging process development, and electrical test. Your work will focus on characterizing semiconductor devices, designing and automating test infrastructure, and extracting key electrical parameters to inform process improvements. This is a hands-on, high-ownership role that requires both deep technical understanding and strong collaboration with process, test, and design engineers.
We're looking for someone who’s excited to work across disciplines developing probe cards, designing test structures, running electrical characterization, and building automation infrastructure. A background in device physics and experience with CMOS modeling (e.g., BSIM) will be valuable, especially for parameter extraction and feedback into process development.
You’ll have the opportunity to work across the full testing stack from test structure design to silicon fabrication and data analysis. Your contributions will help shape how we validate and improve our CMOS processes in a fast-paced, startup environment.
