Apple’s RF Systems Engineering team is seeking a motivated and talented RF engineer to develop and optimize Cellular RF Receiver architectures. In this role, you will architect and deliver wireless solutions for Apple products, working on today's 5G New Radio and pioneering the path to 6G. You will have a unique opportunity to work on the core technologies that enable an outstanding wireless experience for millions of customers worldwide.
As a key member of our industry-leading team, you will drive the evolution of our receiver architectures. You will influence and collaborate with RFIC design, antenna, platform architecture, and software engineering teams to define and implement concepts that deliver uncompromising performance and quality.
You will architect, analyze, and optimize receiver line-ups from the antenna to the digital baseband interface.
You will perform detailed RF line-up analysis, identify RF performance impairment dependencies and crosstalk risks, and develop mitigation techniques.
You will translate system requirements into block-level specifications for the receiver blocks (noise figure, gain, linearity, phase noise, IQ imbalance, etc).
You will define requirements for interference suppression performance, drive validation objectives, and implement interference mitigation strategies.
You will work with other teams to drive the concept-to-product journey, ensuring successful integration, validation, and optimization of receiver enhancements from the architectural phase through to mass production.
BS and a minimum of 10 years relevant industry experience
Minimum 8 years of experience in Radio Receiver design.
Demonstrated System Engineering experience in designing complex communication RF systems (e.g. Cellular, WiFi), with deep expertise in state-of-the-art receiver architectures for sub-6 GHz and mmW frequencies.
Proficiency in using MATLAB and Python for RF system modeling and simulations.
Proficiency in using AI for coding, model generation, and data analysis.
Strong analytical and problem-solving skills, with the ability to communicate complex technical concepts effectively to diverse, cross-functional global teams.
Experience with lab bring-up, system calibration, and debugging RF hardware.
Understanding of RF line-up analysis for modern receiver architectures, including modeling techniques in time and frequency domain.
Deep theoretical and practical understanding of receiver performance metrics and impairments (noise figure, non-linearity, phase noise, IQ imbalance, DC offset, gain and phase errors) and their direct impact on overall system performance.
Understanding of 3GPP standards with a focus on RF requirements and physical layer procedures.
Demonstrated ability to influence and drive innovation and execution across an organization.
Understanding of cellular system use cases, transmit/receive interactions, and coexistence challenges in complex consumer electronics.
Familiarity with modern digital modem architectures.
Familiarity with RFIC design and layout considerations.
