Apple Cellular RF Transmitter Systems Engineer 
United States, Massachusetts, Waltham 
705295353

Today
In this role, you will be part of an industrial-leading RF Transmitter Systems Engineering team. You will work closely with other architecture- and systems engineering teams, RF design teams and SW teams to assess, specify and drive transmitter concepts with focus on innovative performance and uncompromised quality as baseline for differentiating products. Your daily work includes the following tasks: - Translate system-level and performance requirements into requirements for the TX line-up and TX features, including RF control/algorithm specifications for RFICs and system firmware.- Understand and specify RF algorithms (e.g. power control, calibration) and define the RF control infrastructure, including compute resources, interfaces, memory and timing constraints.- Lead HW/SW partitioning of RF algorithms (control functionality), ensuring optimal trade-offs between flexibility, latency and power.- Simulations (e.g., MATLAB, Python, C) for performance analysis.- Identify and analyze critical requirements and provide deep-dive assessments of system performance impact, timelines and risks.- Drive the alignment of requirements, design targets and design trade-offs with other teams such as HW design and SW engineering.- Provide specifications as input for the HW and SW development.
  • BS and 10+ years of relevant shown experience required.
  • Knowledge of cellular radio/3GPP standards (GSM, UMTS, LTE, LTE-A, 5G NR), including RF aspects as well as system use cases and TX waveforms.
  • Familiar with RF systems and transceiver architecture, including lineup design and component-level trade-offs (e.g. gain, linearity, noise, power, thermal).
  • Understand how to translate top-level requirements into specifications for transceiver building blocks, including dimensioning digital control systems for RF applications (CPU, memory, buses, real-time constraints).
  • Experience with HW and SW co-design and clear understanding of trade-offs between digital HW and firmware implementations.
  • Strong analytical skills and the ability to collaborate and communicate across multicultural, global teams.
  • PhD degree with previous work on cellular topics.
  • 5+ years of proven experience in RF, including cellular transmit architectures.
  • Initial expertise in transmitter system-level concepts and control procedures like power control, digital pre-distortion, envelope tracking.
  • Familiar with mmWave architectures, phased array systems and related control concepts.
  • Background in digital signal processing.
  • Understanding of SoC integration constraints and multi-chip RF architectures.
