Embedded Software Engineer

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 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 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.

Responsibilities

- Develop microcontroller firmware for semiconductor processing equipment and components

- Design and implement real-time Linux applications for equipment control and process automation

- Collaborate with mechanical engineers on requirements and controls implementation

Required Experience

- BS in Computer Science, Physics, Computer Engineering, Electrical Engineering, proof of exceptional skills in related fields with practical software engineering experience, or equivalent

- Minimum of 3 years of relevant experience (professional or hobbyist) in real-time embedded software development

- Experience programming in C for microcontrollers. Python for diagnostic applications

- Experience going 0 -> 1 on an embedded system, from defining system requirements, prototyping, and seeing through to production use

- Knowledge of microcontroller peripherals such as ADC, GPIO, PWM, SPI, I2C, and CAN

- Experience working with actuators, sensors and digital signal processing

Nice-to-have

- Background in semiconductors, industrial automation, manufacturing, or other hardware-intensive domains

- Familiarity with controls for motor drivers, mass flow controllers, temperature controllers, or precision actuators
