TL;DR · Wireless PHY Systems Engineer

As a Wireless PHY Systems Engineer on the Wireless SoC team, you will develop end-to-end simulation frameworks and physical-layer algorithms for next-generation modem architectures. You will be responsible for modeling, simulating, and analyzing complex wireless systems across multiple protocol layers, including propagation channel models, RF/antenna behaviors, and signal processing. Your daily work involves collaborating with cross-functional teams to translate algorithm insights into hardware-ready specifications while managing large volumes of field and simulation data to visualize performance metrics like latency and throughput. You will utilize MATLAB, C/C++, and Python along with AI/ML libraries such as NumPy, PyTorch, and scikit-learn to accelerate development cycles. The role focuses on solving technical challenges in Bluetooth-based wireless audio and ultra-wideband sensing, ensuring robust performance across the full signal chain from PHY to MAC layers.

What you'll do

  • Develop end-to-end simulation frameworks covering propagation channels, RF/antenna behavior, and PHY/MAC protocol stacks.
  • Invent and evaluate physical-layer algorithms and DSP techniques for Bluetooth and Ultra-Wideband (UWB) protocols.
  • Process large volumes of field and simulation data to create visualizations of system performance and metrics.
  • Translate algorithm insights into hardware-ready specifications for fixed-point design and RTL vector generation.
  • Perform lab bring-up and validation including FPGA/silicon testing, calibration, and RF equipment operation.
  • Integrate AI/ML techniques to optimize algorithm design, simulation frameworks, and large-scale data analysis.

What we're looking for

  • Bachelor's degree required; MSEE or Ph.D. in electrical engineering, Digital Communications, or Signal Processing preferred.
  • Proficiency in MATLAB and C/C++ for system modeling and simulation.
  • Experience collecting, processing, and visualizing large-scale field and simulation datasets.
  • Familiarity with wireless standards such as Bluetooth, Ultra-Wideband (UWB), or other wireless protocols.
  • Knowledge of analog/RF impairments including phase noise, IQ imbalance, and nonlinearity.
  • Proficiency in Python and data science/ML libraries like NumPy, PyTorch, and scikit-learn.
  • Experience applying AI/ML methods to wireless systems problems and simulation automation.
  • Experience with fixed-point design, RTL vector generation, or High-Level Synthesis (HLS).
