RF Systems Lab Engineer at Apple

Summary

Posted: Sep 16, 2021
Role Number:200289011
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 Systems Lab Engineer, you will be a key member of part of the GNSS RF System team and design, purchase and review the HW platforms and lab equipment to enable this mission.
