GNSS Validation Engineer hos Apple


Posted: Sep 22, 2021
Role Number:200289924
Would you like to join Apple’s growing wireless silicon development team? Do you like hard problems? Global Navigation Satellite Systems (GNSS) space vehicles transmit the power of a lightbulb, they are 13,000 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 cellular SoC team. We are a vertically coordinated engineering team spanning RF, mixed signal analog design, systems engineering, RTL design, DV, 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 Validation Engineer, you will be a key member of our highly innovative GNSS design team, developing GNSS technology and SoC for novel ultra-low-power location-based applications.
