Job description

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 Precision Team operates on the nanometer scale. We make lithography, metrology and motion systems that pattern, inspect and characterize our chips in order to push our process to lower nodes.

About the role

We are seeking a highly skilled and hands‑on Mechatronics Engineer to join our team. You will be responsible for designing, prototyping, and building semiconductor fabrication equipment, subsystems, and tools. This role requires a strong mix of mechanical, electrical, and system integration expertise and a proven track record of rapidly prototyping complex systems and advancing them to the next stage of production.

The ideal candidate moves through design cycles fast and can own the end to end process. Our philosophy is to get things built/tested in days or weeks, not months. Because of this, a portfolio is generally required to apply: show us the things you’ve actually built!

Responsibilities

• Design and iterate on machines, subsystems, test fixtures, inspection tools, and sensors
• Lead system integration efforts, testing, and cross-team coordination
• Develop electrical designs, including PCB design, wiring, power electronics, and sensor integration
• Execute mechanical design of frames, components, and assemblies, with a focus on practical application rather than deep theoretical analysis
• Rapidly prototype, build, and test new designs
• Source and select components while balancing cost, reliability, and performance
• Write light software and firmware to support system operation

Required Experience

• 5 years of experience designing and building electromechanical systems for real‑world applications
• Electromechanical system design and analysis
• Electrical instrumentation experience (scopes, meters, sensors)
• Mechanical design and CAD proficiency
• Hands‑on prototyping, fabrication, and assembly
• Component sourcing and selection
• Light coding and scripting

Nice-to-have

• Circuit design and PCB layout (analog and digital)
• Experience with metrology and sensor technologies
• Motion system selection and control
• Optical components and system integration
