Sr. Software Engineer, RF Silicon (Starlink)



Software Engineering
Redmond, WA, USA
Posted on Wednesday, January 24, 2024

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 millions of 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.

We are seeking motivated, proactive, and intellectually curious engineers who will work alongside world-class cross-disciplinary teams (systems architecture, ASIC design, firmware, pre-silicon verification, post-silicon validation, product engineering, manufacturing/production, and more). In this role, you will be developing software control for cutting-edge next-generation RFICs for deployment in space and ground infrastructures around the globe. These chips are enabling connectivity in places it has previously not been available, affordable or reliable. Your efforts will help deliver solutions that will expand the performance and capabilities of the Starlink network.


  • Bring up new RF silicon as the first engineer to power on chips for the very first time
  • Design and build modular, reusable software driver libraries for low-level silicon control with special attention to timing, throughput, performance, and simplicity
  • Design and build hardware test platforms (hardware-in-the-loop/HTIL/HIL), and validate silicon driver software on physical hardware or FPGA emulators
  • Support software integration into multiple project-specific flight software teams such as satellite phased-arrays and user terminal production


  • Bachelor’s degree in electrical engineering, computer engineering or computer science
  • 5+ years of professional development experience in C, C++, or Python


  • Professional experience developing, debugging, and deploying software that has been used in real-world applications or projects
  • Solid engineering fundamentals and knowledge of electronics, math, physics, and RF communication systems
  • Strong skills in debugging, performance optimization, and unit testing
  • Creative approach to problem-solving and exceptional analytical skills
  • 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 to meet critical milestones


Pay range:
RF Software Engineer/Senior: $160,000.00 - $220,000.00/per year
