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 Role

We are seeking Software Engineering Interns to work on the Fab team for the fall term. The internship begins in September, with a preferred commitment of 4 to 8 months. You will build full-stack applications, tools, and infrastructure for a software-defined semiconductor fab.

This is a deeply broad, multi-domain, hands-on role. You’ll work on control of semiconductor fabrication equipment, and data analysis of semiconductor process development. The software you build will help engineers develop and operate the fab. If you’re excited by building complex features from scratch, and learning new domains quickly, this is a great place to grow.

Our philosophy is to get things built and tested in days or weeks, not months. Because of this, a portfolio (can be your GitHub) is required to apply: show us the things you’ve actually built! For us, a good portfolio includes evidence of software engineering excellence and curiosity.

Responsibilities

  • Develop frontend + backend, data driven applications to run the fab

  • Build software for sequencing and controlling fab operations

Required Experience

  • Pursuing a BS in Computer Science, Computer Engineering, or demonstrated exceptional skill in software engineering

  • Strong programming skills in Rust and Go or Typescript plus a strong desire to learn

  • Solid understanding of systems fundamentals: memory, performance, concurrency

  • Experience building non-trivial software projects from scratch (personal, academic, or professional)

  • Interest in one or more of the following areas: databases, visualization, data processing pipelines

Nice-to-have

  • Experience with interactive software such as Figma, Blender, CAD tools, KiCad, or scientific computing environments

  • Familiarity with schema evolution, database migrations, or serialization formats like Protobuf

  • Understanding of collaborative or distributed systems (e.g., CRDTs, OT, WebSockets)

  • Appreciation for texts such as Structure and Interpretation of Computer Programs and Designing Data-Intensive Applications: The Big Ideas Behind Reliable, Scalable, and Maintainable Systems

  • Exposure to advanced 2D/3D visualization, simulation, or novel user interfaces

Working at fab2

We're an early-stage hardware startup with solid funding, world-class advisors, and offices in Austin, TX and San Francisco, CA. fab2 is committed to fair and equitable compensation. Software Interns are paid hourly, at a rate equivalent to an annualized $114,000–$132,000 depending on experience and education. Actual earnings vary with hours worked.

Internship Benefits:

  • Housing Stipend to help with first month expenses

  • Lunches daily, Dinners 3x per week, Stocked Office Kitchen with Snacks and Spindrifts

  • Weekly Learning & Development opportunities
