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

TheVacuum Systemsteamis responsible for designing, prototyping, validating, and scaling core semiconductor fabrication equipment. Tool families include Anneal, Deposition, Etch, and Supporting Infrastructure, with goals for each ranging from fundamental design to automation readiness to manufacturing scale-up.

About the role

As a Senior Mechanical Design Engineer at fab2, you'll design, iterate on, and build specialized equipment for semiconductor fabrication.

We're looking for hands-on engineers across various disciplines to design, iterate on, and build complex systems. Whether tackling heavy design challenges, integrating mechanical, optical, and electronic components, or automating production and manufacturing processes, our philosophy is to get things built and tested in days or weeks, not months, with a focus on viable solutions that meet real production needs.

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

• Own semiconductor fabrication systems and subsystems end-to-end, including deposition, etch, annealing, and plasma tools, as well as subsystems such as mass flow controllers, pressure sensors, valves, and pumps.

• Design and iterate on machines and subsystems for semiconductor fabrication

• Create mechanical designs including frames, components, and assemblies

• Partner closely with the process, electrical, software, and production teams

• Demonstrated ability to design and ship machined and fabricated metal parts into working systems.

• Comfortable working with pumps, valves, fittings, tubing, chambers, and thermal systems

Nice-to-have

• Knowledge/experience with any of: plasma systems, CVD, ALD

• Familiarity with leak detection techniques and vacuum diagnostics

• Experience with productionization and testing

Working at fab2

We’re an early-stage hardware startup with solid funding, world-class advisors, and labs/offices in Austin, TX, Lockhart, TX, and San Francisco, CA.
