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 The Manufacturing Software Lead owns the software systems that manufacture, test, and calibrate for all of fab2's semiconductor equipment. This involves architecting software for device assembly, provisioning, calibration, and end-of-line test. You will implement firmware and software changes in production equipment while also building dedicated software for manufacturing test. Responsibilities • Own manufacturing software for all in-house hardware, from components (MFCs, pumps, valves) through assembled processing tools • Design and build automated test and calibration systems for fixtures, test firmware, and host-side test software • Write production software in C, Python, and Rust which include firmware test modes, calibration and characterization routines, provisioning and flashing tools, and test-station applications • Partner with manufacturing engineers on test station design and implementation • Uphold code and testing standards through feedback and code review • Hire and mentor team members Required Experience • BS in Computer Science, Computer Engineering, Electrical Engineering, Physics, or a related field, or equivalent practical experience • 5+ years developing software for the manufacture or test of physical products (test automation, calibration, end-of-line test, production tooling) • Proficiency in C and Python • Working knowledge of electronics and instrumentation: reading schematics, using bench test equipment • Experience with production data systems: traceability, test databases, and analysis of manufacturing data Nice-to-have • Background in semiconductor equipment, fluid/gas handling components, vacuum systems, or scientific instrumentation • Experience testing or calibrating mass flow controllers, pumps, pressure/temperature sensors, or precision actuators • Experience with MES integration or building lightweight MES functionality • Familiarity with FMEA, SPC, or other quality and reliability practices • Experience scaling from prototype builds through production ramp • Experience with Rust Working at fab2 We’re an early-stage hardware startup with solid funding, world-class advisors, and a lab/office in Austin, TX, Lockhart, TX, and San Francisco, CA.
