The role
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.
RAN VALIDATION 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 RAN Validation Engineer on the Starlink Mobile program, you will be responsible for validating and optimizing the 4G/5G RAN software protocol stack. This includes developing automated test cases for feature validation, performing lab and field testing, analyzing and optimizing network performance, and collaborating with developers to resolve complex issues.
