Additional Information

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. SR. RAN SOFTWARE ENGINEER (STARLINK MOBILE) SpaceX is developing a satellite-to-mobile network to deliver ubiquitous cellular connectivity worldwide through the Starlink constellation. We are partnering with mobile network operators globally to provide direct-to-cell service, extending coverage to billions of existing cellular devices. Starlink Mobile was designed to connect the unconnected, and this new product will greatly expand that mission by extending coverage to billions of existing cellular devices. Applications include connecting hikers in national parks, emergency responders, rural communities, remote sensors, and people in emergency situations. As a Sr. Software RAN Engineer on the Starlink Mobile program, you will lead the validation and optimization of the 4G/5G RAN software protocol stack. This role requires strong software engineering skills to build scalable test automation frameworks and work directly with other software developers to triage and resolve complex 4G/5G protocol stack software issues.
