RF Power Engineer

About Atomic Semi

Atomic Semi is building a small, fast semiconductor fab.

It’s already possible to build this with today’s technology and a few simplifications. We’ll build the tools ourselves so we can quickly iterate and improve.

We’re building a small team of exceptional, hands-on engineers to make this happen. Mechanical, electrical, hardware, computer, and process. We’ll own the stack from atoms to architecture. Our team is optimistic about the future and we want to continue pushing the limits of technology.

Smaller is better. Faster is better. Building it ourselves is better.

We believe our team and lab can build anything. We’ve set up 3D printers, a wide array of microscopes, e-beam writers, general fabrication equipment - and whatever is missing, we’ll just invent along the way.

Atomic 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 looking for an enthusiastic RF power engineer who can rapidly develop compact RF systems from gathering requirements to the production stage. 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. The ideal candidate is self driven and proactive in figuring out the necessary tasks to complete. A portfolio of previous work is required for this application. Show us what you have built!

Responsibilities

  • Designing 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

  • Creation of firmware requirements

  • Source components and lead manufacturing effort

Required Experience

  • Complete end to end ownership 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
