Snr. Mixed Signal Chip Design Engineer

Engineering | Sunnyvale, CA | Full Time

Job Description

About Us

Kumu Networks is revolutionizing the way wireless systems are built using an innovative full-duplex wireless design that its co-founders developed in their research at Stanford. 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!


The Mixed Signal Design Engineer will be a key contributor to the evolution of Kumu Networks full-duplex technology. He/she will work with Kumu’s core technology team to drive the miniaturization of self-interference cancellation into integrated circuits. The ideal candidate will have excellent fundamentals and understand the pros and cons of different analog implementations of a desired function, as well as possess the creativity to use standard components in nontraditional and very innovative ways. The candidate will also have a deep understanding of different IC technologies (standard CMOS and RFSOI,) and the design flow from concept all the way through to release for production.
