SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.


At SpaceX we’re leveraging our experience in building rockets and spacecraft to deploy Starlink, the world’s most advanced broadband internet system. Starlink is the world’s largest satellite constellation and is providing fast, reliable internet to 1M+ users worldwide. We design, build, test, and operate all parts of the system – thousands of satellites, consumer receivers that allow users to connect within minutes of unboxing, and the software that brings it all together. We’ve only begun to scratch the surface of Starlink’s potential global impact are looking for best-in-class engineers to help maximize Starlink’s utility for communities and businesses around the globe.

Our Satellite Payload Engineering team develops the RF devices that power our satellites and ground antennas - from power amplifiers to waveguide components to reflectors to antennae. As a RF Systems Engineer, you’ll be responsible for simulating and modeling the terrestrial and orbital communication systems for Starlink and help define their architectures and specifications. You’ll also support our certification efforts as a liaison with our regulatory teams and various governmental bodies and industry organizations.


  • Simulate and model communication systems
  • Work with system architects, RF engineers, antenna engineers, modem/DSP, and ASIC engineers to partition functions between hardware and software domains
  • Assess the feasibility of various designs in support of architecture definition
  • Derive top level specifications for RF links and RF and antenna subsystems
  • Characterize and analyze system performance
  • Provide technical support to regulatory, coordination, and market access teams


  • Bachelor’s degree in an engineering discipline
  • Experience in MATLAB, Python, C++ or other tools for modeling and analyzing RF systems
  • 10+ years of research and/or industry experience in RF/microwave system specification/design


  • Master’s degree or PhD in an engineering discipline with emphasis in RF/microwave circuits or electromagnetic theory
  • Experience modeling complicated communications systems for analysis
  • Thorough understanding of RF passive components
  • Thorough understanding of digital communication systems, spread spectrum, single and multi-carrier techniques, modulation types such as PSK, APSK, QAM
  • Thorough understanding of electromagnetic propagation and antenna systems
  • Knowledge of RF transceiver architectures and digital communication theory
  • Experience in RF/microwave design in the Ku, Ka, V and E-band frequency range
