Job description

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 https://www.youtube.com/@SamZeloof and Jim Keller https://en.wikipedia.org/wiki/Jim_Keller_(engineer). 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 Precision Team operates on the nanometer scale. We make lithography, metrology and motion systems that pattern, inspect and characterize our chips in order to push our process to lower nodes. About the role We are seeking a highly skilled and hands-on Optomechanical Engineer to join our team. This role is for someone who has internalized precision machine design as a discipline and has a proven track record of rapidly prototyping complex optical systems and advancing them to the next stage of production. Our philosophy is to get things built and tested in days or weeks, not months. Because of this, a portfolio is generally required to apply: show us the things you’ve actually built! The core responsibility of the job is the design, assembly, testing, and debugging of new electromechanical and optical systems.
