TL;DR · Cellular PHY Systems Engineer

The Cellular PHY Systems Engineer joins the system engineering team to work on modem systems features and requirements. This role involves pre- and post-silicon bring up, as well as the validation of end-to-end cellular systems. The engineer will map systems algorithms and requirements to hardware and firmware architecture while performing simulation and emulation-based validation of control flows and PHY/L1 algorithms. Key responsibilities include collaborating with SoC, PHY, and software teams to meet system requirements. Required skills include knowledge of 6G, 5G NR, and 4G LTE standards, along with signal processing expertise for LDPC, Polar, and Turbo encoder designs. Candidates must use Matlab, C/C++, and Python for algorithm development, modeling, and link-level simulation to solve complex wireless communication and signal estimation problems.

What you'll do

  • Perform pre- and post-silicon bring-up and validation of end-to-end cellular systems.
  • Map system algorithms and requirements to hardware and firmware architecture.
  • Conduct simulation and emulation-based validation of control flows and PHY/L1 algorithms.
  • Design algorithms for LDPC, Polar, Turbo encoding, signal estimation, and MIMO detection.
  • Develop models and link-level simulations using Matlab, C/C++, and Python.
  • Execute chip bring-up using spectrum analyzers, signal generators, and protocol test equipment.
  • Perform lab testing and characterization of wireless communication systems.
  • Analyze end-to-end timelines for time-critical algorithms.

What we're looking for

  • BS degree is required.
  • 10+ years of relevant experience is required.
  • Knowledge of 6G, 5G NR, 4G LTE, and PHY Uplink channels and signals is required.
  • Deep knowledge of communication system theory and signal processing is required.
  • Experience with Matlab, C/C++, and/or Python for algorithm development and simulation is required.
  • Experience in low power algorithm design for power critical applications is helpful (preferred).
  • Experience in E2E timeline analysis for time-critical algorithms is helpful (preferred).
  • Experience in chip bring-up using lab equipment and wireless communication systems is helpful (preferred).
