Principal Software Engineer (Direct To Cell)
Company: SPACE EXPLORATION TECHNOLOGIES CORP
Posted on: November 25, 2022
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 .
