About the role

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 Role

We are seeking a Infrastructure and Site Reliability Intern for the summer term. The internship begins in May or June, with a preferred commitment of 4 to 8 months. You will design, build, deploy, and manage the on-prem backend infrastructure that powers our small, fast semiconductor fab. This is a broad role encompassing all aspects of backend infrastructure and services. Our philosophy towards infra is minimal, understandable, on-site, and close to the hardware. You won’t find much docker, cloud services, or kubernetes. Instead, there is a lot of bare-metal linux, systemd, and single file binaries. You’ll see a lot of rust and go and occasionally some python. What matters most is that you’ve already built real things, you love getting close to the metal, and show strong signs of engineering excellence. If you’re excited by performance engineering, building complex features from scratch, and learning new domains quickly, this is a great place for you. Our philosophy is to get things built and tested in days or weeks, not months. Because of this, a portfolio (can be your GitHub) is required to apply: show us the things you’ve actually built! For us, a good portfolio includes evidence of software engineering excellence and curiosity.
