Cellular RF Receiver Systems Engineer

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 contribute to the receiver line-up for our next-generation cellular solutions. You will influence and collaborate with RF circuit design, platform architecture, and software engineering teams to implement performance-enhancing 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.
