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.
Don’t see the right role for you?
We are always looking to meet exceptional people. Our product is “full-stack” and spans several engineering disciplines. Here’s a non-exhaustive list of what we’re working on:
Mechanical systems (high precision mechanical design, control systems, fluids, temperature & vibration control, optics)
Electrical systems (RF, high voltage, FPGAs)
Software (firmware, low-latency controls, data analysis, robotics and automation)
Nanofabrication (process engineering, chemistry, device physics, transistor modeling)
We’re moving really fast and our needs are changing fast. If you think you can help us build something great, let’s chat!
