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 https://www.youtube.com/@SamZeloof and Jim Keller https://en.wikipedia.org/wiki/Jim_Keller_(engineer). 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 role We’re hiring full-stack Mechanical Engineering Interns for the winter term. The internship begins in January, with a preferred commitment of 4 to 8 months. We’re rebuilding the chip fabrication process from the ground up, so you’ll be exposed to some really interesting and impactful work. Our engineering projects are highly interdisciplinary and span domains such as structures, optics, robotics, heat transfer, physics, and chemistry. As a startup, we offer interns a ton of ownership and mission-critical work. The ideal candidate has hands-on experience working in at least one of these areas and broad exposure across other domains. Our philosophy is to get things built and tested in days or weeks, not months. Because of this, a portfolio is required to apply: show us the things you’ve actually built! If you’ve shipped a medium-to-high complexity system through a personal project or previous internship, you’d be a good fit here. Responsibilities - Design, prototype, and build semiconductor fabrication equipment - Write mechanical drawings and documentation - Perform detailed analysis and simulations to evaluate electromechanical designs - Drive prototypes into production in collaboration with our manufacturing and supply chain teams Required Experience - Pursuing a Bachelor’s Degree or higher in engineering - Ability to learn quickly and troubleshoot technical problems - Hands-on prototyping experience and the ability to move through design cycles quickly - Hands-on experience with electromechanical assembly design and analysis from coursework, internships, or personal projects - Strong foundation in mechanical engineering (Solidworks/Onshape, simulation, materials selection, etc.) Nice-to-have - Familiarity with semiconductor processing— ALD, CVD, PVD, photolithography, etc. - Strong foundation in electrical engineering (KiCad/Altium, microcontrollers, embedded systems, digital circuits, etc.) - Experience in one of the following domains: optical engineering, precision machine design, or vacuum systems 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. fab2 is committed to fair and equitable compensation. Hardware Interns are paid hourly, at a rate equivalent to an annualized range of $108,000–$126,000 depending on experience and education. Actual earnings vary with hours worked.
