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.
Responsibilities
Collaborate with process and electrical engineers to design probe cards and test structures
Design and fabricate CMOS test chips for characterization and calibration
Develop and implement test plans to extract key device parameters (e.g., threshold voltage, mobility, leakage)
Deploy parameter extraction tools and methods (e.g., BSIM models) to characterize devices and model performance
Analyze test data to provide feedback to process engineers, helping improve materials and process flows
Develop and maintain test automation infrastructure for streamlined electrical characterization
Document test results and characterization findings clearly and rigorously
Required Experience
BS, MS, or PhD in Electrical Engineering, Applied Physics, or a related field
Strong understanding of CMOS device physics and electrical characterization
Experience with probe station operation
Familiarity with parameter extraction techniques and device modeling (e.g., BSIM)
Experience with lab instrumentation and test automation
Hands-on experience with semiconductor device fabrication and test structures
Nice-to-have
Experience with process development kits (PDKs) and test chip layout
Experience with cleanroom fabrication and full CMOS process flow
Experience conducting reliability testing and analysis
