Embedded Software Engineer

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 tool software group builds Linux control software and microcontroller firmware for fab2’s in-house semiconductor manufacturing equipment. This includes software for sequencing, recipe execution, interlocks, operator user interfaces, diagnostics, and real-time microcontroller firmware.

About the Role

We’re hiring embedded software engineers to help build the software systems behind our fab equipment. You’ll develop firmware for real-time control of semiconductor processing tools, working from early system definition through board bring-up, driver development, control logic, state machines, communications interfaces, and production deployment.

This is an end-to-end role for engineers who enjoy debugging across hardware and software boundaries. You’ll collaborate with electronics and mechanical engineers on schematics, system requirements, controls implementation, and tool integration. You’ll also work on Linux-based Rust applications used for equipment control, operator interfaces, diagnostics, and automation.
