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
fab2 prints chips. fab2 prints fabs. The Software team builds the software that runs it all.
About the role
We’re looking for a Software Engineer to build the software that runs chip fabrication at fab2.
You’ll work on the core application engineers use to define processes, run tools, track wafers, monitor equipment, and understand what happened after every run. This is a greenfield role for someone who wants to work across software and physical systems, own large pieces of the stack, and make a complex fab easier to program and understand.
Responsibilities
Own core parts of the software platform that runs chip fabrication at Fab2.
Design the systems that model tools, recipes, wafers, masks, and every process run through the fab.
Build interfaces for controlling equipment and monitoring the state of the fab in real time.
Ingest and make sense of high-frequency telemetry, video, logs, and run data from fabrication equipment.
Develop tools for metrology, process analysis, and SPC that help engineers understand what happened and decide what to run next.
Create a complete history for every wafer, connecting its recipes, equipment state, sensor data, and results.
Partner directly with process and hardware engineers to turn process research into production manufacturing capabilities
Required Experience
Strong software engineering fundamentals and experience shipping production systems.
Full-stack ability across frontend, backend, databases, and system design.
Ability to model complex physical processes and turn them into simple, reliable software.
Strong product instincts and willingness to work directly with engineers using the software.
Effective with AI coding tools while still able to read, write, debug, and reason about code independently.
Strong technical communication and a high degree of ownership.
Nice-to-have
Experience building MES, laboratory automation, or other software that coordinates complex physical workflows.
Founding engineer, CTO, or early-stage startup background.
Background working with hardware, embedded systems, robotics, or other physical systems.
Familiarity with semiconductor equipment, process control, or fab operations.
Hands-on work with telemetry, time-series data, industrial controls, or real-time systems.
