LTE System Integration & Test Lead

Engineering | Santa Clara, CA | Full Time

Job Description

About Us:

Kumu Networks is revolutionizing the way wireless systems are built, using an innovative full-duplex wireless design developed by its co-founders at Stanford University. Wireless full-duplex allows a radio to transmit and receive signals at the same time using a single frequency channel. Kumu's patent pending full-duplex technology changes the basic assumptions on which current wireless radios are built, allowing for improved performance and reduced complexity across a variety of wireless devices and markets. Come help us change the future of wireless!
