This is a Contract position in Chicago, IL posted October 21, 2021.

Summary Posted: Oct 7, 2020 Role Number: 200197609 Would you like to join Apples 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.

Wed like you to consider being a part of our team.

As the RF Systems Lab Manager, you will be part of the GNSS RF System team and design, purchase and review the HW platforms and lab machines to enable this mission.

Key Qualifications The ideal candidate will have the following qualifications: Design RF centric boards for internal validation usage Review, represent and promote the team interests with regards to other boards related to our product and layout designs Debug boards issues related to poor boards design practices, pin point the issue, simulate it and come up with suggested solution Board bring up to a stable phase Capable of reworking SMAs and BGAs components up to 0201 Proven experience in RF test development, debug, and reporting Strong RF background and familiarity with RF systems fundamentals Shown experience working with RF test equipment (network analyzer, spectrum analyzer, vector signal generator, etc.) Knowledge in test and script development (Python, PERL, TCL) Good written and verbal communication skills Proven understanding of RF, PLL, and general wireless systems measurements (i.e.
