Requirements

Candidates must possess a Bachelor’s degree in Electrical Engineering or Physics, along with at least 8 years of hands-on experience in RF system design, integration, and/or testing. Extensive experience with FEA RF/EM modeling using software such as HFSS, CST, or Comsol is required, as is experience designing and commissioning ICRH antennas and High-Power RF systems. Familiarity with impedance matching circuits and Matlab or Python is a plus.

Responsibilities

As a Senior RF Antenna Engineer, you will integrate, test, and commission RF system components including transmission lines, antennas, splitters/combiners, and matching networks. You will also develop testing and commissioning processes, design and integrate RF signal detection and measurement circuits, and contribute to the build and test of prototype ICRH antennas and components, ultimately sustaining fusion reactions by feeding >25MW of RF power into the tokamak.

Commonwealth Fusion Systems

Develops and commercializes fusion energy systems

About Commonwealth Fusion Systems

Commonwealth Fusion Systems focuses on developing fusion energy as a clean and sustainable power source. The company utilizes advanced magnet technology, created in partnership with MIT, to build smaller and more affordable fusion systems called tokamaks. These devices use magnetic fields to confine plasma in a toroidal shape, which is an effective method for achieving fusion. Currently, CFS is manufacturing high-temperature superconducting magnets and constructing SPARC, the first commercially-relevant net energy fusion machine. The success of SPARC is intended to lead to the development of ARC, the first fusion power plant. CFS differentiates itself from competitors by its commitment to scientific integrity and a mission-driven approach, focusing on delivering cost-competitive fusion energy to help combat climate change. The ultimate goal is to provide a reliable and abundant energy source for energy providers and industries that require significant power.
