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! Apple's RF Systems Engineering team is looking for a hardworking, independent engineer with a proven track record in the area of transceiver systems engineering. As a GNSS SoC RF Systems Architect, you will work closely with Platform Architecture, RFIC design and PHY teams to assess, design and drive RF system innovations with a focus on groundbreaking performance under real-life conditions and clear differentiation from other competitors.
Description
Translate system level GNSS receiver requirements into detailed specifications for the antenna, RF front end, and integrated RX chain (including the breakdown to block / component level). Run static analysis for specific scenarios defined for the product by the architecture teams. Select, simulate and specify RF architectures suitable for integration into a GNSS receiver SoC. Drive the further development of the simulation environment and modeling. Prepare specifications as input for RFIC design team and FW team. Analyze the receiver chain by means of simulations in MATLAB, and level plan / impairment analysis (SysCalc). Identify and analyze critical requirements, and provide assessments with respect to critical metric impact, timeline and risks. Solve sophisticated and interdisciplinary problems that are related to the GNSS receive system. Support RF SiVal in defining and carrying out measurements to validate RX performance. Assist with silicon debug, and propose solutions and workarounds as needed.
Minimum Qualifications
- Minimum requirement of BS and 3+ years of relevant industry experience.
- 3+ years experience in RF Systems performance criteria and concepts such as AGC, noise figure, sensitivity/de-Sense, phase noise, spurious responses, harmonics and intermodulation.
- Strong analytical and interpersonal skills with an ability to thrive in a multi-functional environment.
- Excellent verbal and written communication skills.
Preferred Qualifications
- MSEE or beyond is preferred.
- 4+ years of proven experience in RF, including receiver system architecture design, with emphasis on integrated SoC solutions
- Expertise in RF System concepts and procedures for wireless systems including calibrations, analysis of receiver chains from RF antenna to digital baseband IQ, and translating top-level requirements into specification items for transceiver building blocks and RF components (e.g. LNA, Mixer, PLL, ADC, and Filters).
- Familiarity with Receiver Digital Signal Processing blocks (e.g. decimation, filtering, resampling, IQ correction, etc)
- In-depth knowledge of wireless radio standards (Connectivity, Cellular or GNSS), including their implications on system specifications.
