GNSS RF System Debug Engineer

San Diego , California , United States



Posted: Jan 22, 2021

Role Number: 200218088

Would you like to join Apple's growing wireless silicon development team? Global Navigation Satellite Systems (GNSS) space vehicles transmit the power of a lightbulb, they are 13000 miles away, and are moving four kilometers per second. The received signals are commonly one hundred times weaker than cosmic microwave background radiation left over from the Big Bang and arrive next to interfering signals ten billion times stronger, just few MHz away. Our GNSS team is part of Apple's wireless SOC team. We are a vertically integrated engineering team spanning RF, mixed signal analog design, systems engineering, Design Verification, RTL design, firmware and software engineering, Test, and Validation. Our focus is on highly energy efficient and robust GNSS receiver design. We develop GNSS technology that touches hundreds of millions of lives, something we are passionate about. We'd like you to consider being a part of our team. As a GNSS RF System Debug Engineer, you will be a key member of Apple's cellular team, driving cellular development for our next generation wireless products used by millions. Come to Apple and do your life's best work!
