Principal Software Engineer (Direct To Cell)

Company: SPACE EXPLORATION TECHNOLOGIES CORP
Location: Redmond
Posted on: November 25, 2022

Job Description:

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 ofenabling human life on Mars.
PRINCIPAL SOFTWARE ENGINEER (DIRECT TO CELL)
SpaceX is developing a breakthrough new direct to cell satellite network to bring ubiquitous cellular connectivity worldwide via the Starlink constellation. We are partnering with telecommunication companies around the world to bring this service directly from satellites to existing cell phones, with the goal of providing coverage anywhere a phone can see the sky.
More than 20% of the United States and 90% of the Earth remain uncovered by existing wireless networks, negatively impacting communities around the world. Starlink was designed to connect the disconnected and this new product will greatly expand that mission, extending Starlink's potential reach to billions of existing cellular devices. The applications range from connecting hikers in national parks, emergency workers such as firefighters, rural communities, remote sensors and devices, and people and devices in emergency situations. You can learn more about this recently announced effort .
