Why this role exists
Fab2 raised $500M Series A on 18 Sept 2026.
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 are looking for an enthusiastic RF power engineering intern who can rapidly develop compact RF systems from gathering requirements to the production stage. The internship begins in May or June, with the option for preferably a 4 to 8-month commitment. You will get to own entire RF power systems while working closely with other engineers to enable small and fast semiconductor plasma systems. You will be exposed to many diverse problems and will need to move through design cycles quickly. 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 - Contribute to the design of complete RF power systems from architecture to schematic to layout - Ensure accurate RF power diagnostics and metrology - Collaborate with engineers and scientists to gather system requirements - Help define of firmware requirements - Source components and lead manufacturing effort Required Experience - Experience building of RF systems - RF resonant power amplifier design in the 100s of Watts range - RF power measurement sensor design - Hands on prototyping and testing - Cable harness design, documentation, and fabrication Nice-to-have - Advanced degree in power electronics or related field - Plasma systems experience - Systems engineering and integration 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 practices. Hardware Interns are paid an hourly rate equivalent to an annualized range of $108,000-126,000, depending on experience and education level. Actual earnings will vary depending on internship length and hours worked.
