GNSS RF System Engineer

Are you a dedicated individual wanting to join Apple's GNSS RF Systems Engineering team as an RF Systems Engineer! Part of Apple's world leading wireless SoC group, you’ll join a vertically integrated engineering team spanning RF, mixed-signal analog design, systems engineering, design verification, RTL design, firmware and software engineering, testing, and validation. Are you interested in doing work that challenges you, expands your thinking, provides innovative solutions for future problems while driving your growth as a recognized technical leader in the cellular industry. Be part of our team of industry-leading experts in Cellular GNSS RF and do the most fulfilling work of your life. At Apple GNSS, we are dedicated to developing GNSS technology that touches and transforms the lives of hundreds of millions around the globe!

In this role, you will join a growing RF Systems Engineering team dedicated to developing and innovating highly energy-efficient, robust GNSS receiver architectures. These architectures are designed to seamlessly coexist with various co-located high-power RF technologies operating in adjacent frequency bands. You will collaborate closely with Platform Architecture, RFIC Design, and PHY teams to evaluate, design, and orchestrate RF system innovations, emphasizing outstanding performance in real-world conditions. YOUR DAILY WORK INCLUDES THE FOLLOWING TASKS:

• Translate system level GNSS receiver requirements into detailed specifications for the integrated RX chain (including the breakdown to block / component level).
• Analyze the receiver chain by means of simulations in MATLAB, and level plan / impairment analysis (SysCalc). 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.
• Prepare specifications as input for RFIC / RTL design teams and FW teams.
• Tackle sophisticated and interdisciplinary problems that are related to the GNSS receive system, in collaboration with the GNSS systems team.
• Support validation teams in defining and carrying out measurements to validate RX performance.
• Assist with silicon debug, propose solutions, and workarounds as needed.
• Collaborate with Front End, Cellular, and CoEx teams on platform architectures.
• Drive the further development of the simulation environment and modeling.

• BS and a minimum of 10 years relevant industry experience.
• Strong background in Wireless Communications space (e.g. Connectivity, Cellular, GNSS; RF and/or PHY).
• Solid programming skills.

• MSEE or beyond is preferred.
• 10+ years of proven experience in RF/PHY system/architecture design, with emphasis on integrated SoC solutions.
• Knowledge of Wireless Transceiver Systems and RF concepts (e.g. AGC, NF, phase noise, spurs & harmonics, intermodulation, TRX calibrations).
• Design and simulation of analog/digital signal processing paths.
• Digital Signal Processing blocks (e.g. decimation, filtering, resampling, IQ correction).
• Wireless communications system modeling (e.g. Matlab, ADS, C++).
• Balanced combination of innovation demeanor and understanding of practical constraints of product development.
• Excellent communication skills, both written & verbal especially in a multi-functional environment.
