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 3M+ 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 and are looking for best-in-class engineers to help maximize Starlink’s utility for communities and businesses around the globe.

As a Wireless Software Engineer on these programs, you will be solving a wide range of novel engineering challenges:

  • Firmware, embedded, and signal processing software running on custom hardware that flies the world’s largest fleet of spacecraft.
  • Cutting-edge networking algorithms capable of connecting thousands of satellites to millions of users in real time.
  • Infrastructure and tools enabling a highly reliable, software-defined global network.

Our software engineers are responsible for the complete lifecycle of the software they create, including development, testing, and support.


  • Design, implement, test, and maintain physical and MAC layer software of the wireless software stack for the Starlink communications network.
  • Participate in architecting current and next-gen Starlink hardware and signal processing algorithms.
  • Participate in hardware bring-up, debugging, verification and launch.
  • Work with other teams for cross-layer integration of the end-to-end system.
  • Develop prototypes to prove out key design concepts and quantify technical constraints.
  • Collaborate with other engineers to plan and organize the development of our products.


  • Bachelor’s degree in computer science, engineering, math, or STEM discipline; OR 2+ years of professional software engineering experience, programming with C or C++ in lieu of a degree.
  • Experience working with wireless software or network protocols.


  • Strong knowledge of wireless communications, signal processing and/or network protocols.
  • Knowledge of RF systems and fundamentals: noise figure, link budget, non-linearity.
  • Experience writing software for RF/mixed-signal integrated circuits and/or systems, such as phase-locked loops, mixers, data-converters, RF attenuators.
  • Familiar with design and implementation of Digital Signal Processing algorithms and techniques: FFT, time and frequency domain equalizer, channel estimation, pilot tracking, digital pre-distortion, doppler compensation.
  • Experience with lab equipment such as RF spectrum analyzer, network analyzer, signal generator, oscilloscope.
  • Experience in any of physical and/or MAC layers in broadband access technologies such as: Wi-Fi, LTE, 5G or satellite broadband.
  • Creative approach to problem solving, exceptional analytical skills and engineering fundamentals.
  • Strong skills in debugging, performance optimization, and unit testing.
  • Excellent communication skills both written and verbal.
  • Ability to work effectively in a dynamic environment with changing needs and requirements.


  • Must be willing to work extended hours and weekends as needed.
