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 team builds the software that runs fab2's semiconductor fabrication tools. We work across the stack, from microcontroller firmware and real-time control to Linux applications for calibration, diagnostics, simulation, build/release infrastructure, and over-the-air deployment.
Our software sits close to the hardware and directly affects tool performance, uptime, process repeatability, and fab throughput. We partner closely with electrical, mechanical, process, and fab teams to bring new equipment online and scale it into production.
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
Lead microcontroller firmware development 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, or Electrical Engineering, or equivalent; or proof of exceptional skills in related fields with practical software engineering experience.
Minimum of 8 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
Experience programming in Rust
Familiarity with embedded Linux (Yocto, Buildroot)
Interest in applied math, linear algebra, numerical methods
Familiarity with failure mode and effects analysis (FMEA) or similar reliability-focused design practice
Familiarity with full-stack software development for working with adjacent teams
