What the Team is Saying
What We Do
For over 40 years, we’ve been challenging the status quo and evolving our company to anticipate opportunities for business growth, industry innovation and greater customer choice.
Recently, DISH and EchoStar successfully completed their merger, joining forces to deliver on our Vision: To Change the Way the World Communicates. Originally established as one company, in 2008, the two companies were spun off as separate entities and forged ahead so each could focus on and expand their unique capabilities. In that time as separate entities, our teams achieved remarkable milestones—launching satellites into space, connecting millions to their favorite entertainment and reimagining wireless communication.
As we merge our teams, we are strategically positioned for success, poised to emerge as a global leader in terrestrial and space connectivity. We are cleared for takeoff. Join us in a Connectivity Revolution.
Why Work With Us
At EchoStar, we work to create opportunity and cultivate an environment where people thrive. Between our brands, our partners, our teams and our customers, the opportunities are endless. Get started on your next career adventure with EchoStar!
