About the role

Join Apple's Wireless SoC team to define next-generation modem architectures, develop physical-layer algorithms, and build end-to-end simulation frameworks for wireless systems. Focus areas include Bluetooth-based wireless audio and ultra-wideband (UWB) sensing, with contributions spanning signal chain modeling, algorithm development, hardware-software integration, and AI-assisted analysis to accelerate development and improve end-to-end model accuracy and scalability.

Responsibilities

  • Design and develop end-to-end simulation frameworks encompassing propagation channel models, RF/antenna abstractions and PHY/MAC protocol stacks
  • Invent, derive, and evaluate physical-layer algorithms and DSP techniques for Bluetooth, UWB, and other wireless protocols
  • Collaborate with cross-functional teams to model and visualize system performance across the full signal chain
  • Process and analyze large volumes of field and simulation data; develop clear, user-friendly visualizations of complex results including measurement accuracies, system latencies, and protocol performance metrics
  • Partner with digital and analog design teams to translate algorithm insights into hardware-ready specifications, supporting fixed-point design and RTL vector generation
  • Support lab bring-up and validation activities, including FPGA/silicon testing, PHY/RF/MAC debugging, calibration procedures, and lab equipment operation
  • Utilize AI/ML techniques across all aspects of the role — including algorithm design and optimization, simulation framework development, post-processing and visualization of large-scale datasets, and lab-based testing and debugging workflows

Qualifications

  • Bachelor's degree
  • Hands-on software programming skills for system modeling and simulation, with required proficiency in MATLAB and C/C++
  • Experience collecting, processing, and visualizing large-scale field and simulation datasets, including performance metrics such as measurement accuracy, latency, and throughput
  • Familiarity with analog/RF impairments common in wireless systems (e.g., phase noise, IQ imbalance, nonlinearity)
  • Experience with or knowledge of wireless standards such as Bluetooth, Ultra-Wideband (UWB), or other wireless protocols
