Cellular PHY Systems Engineer

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 architectures.
• Conduct simulation and emulation-based validation of control flows and PHY/L1 algorithms.
• Design algorithms for LDPC, Polar, and Turbo encoding, signal estimation, and detection.
• Develop models and link-level simulations using Matlab, C/C++, and Python.
• Execute chip bring-up using protocol test equipment, spectrum analyzers, and signal generators.
• Perform lab testing and characterization of wireless communication systems.
• Analyze E2E timelines for time-critical algorithms and low-power algorithm design.

What we're looking for

• MS in EE or related field.
• Knowledge of cellular communication standards including 5G NR, 4G LTE, and PHY uplink channels and signals.
• Deep knowledge of communication system theory and signal processing for algorithm design.
• Experience with Matlab, C/C++, and/or Python for algorithm development, modeling, and link-level simulation.
• Experience in low power algorithm design for power critical applications (preferred).
• Experience in E2E timeline analysis for time-critical algorithms (preferred).
• Experience in chip bring-up using lab equipment such as protocol test equipment, spectrum analyzers, and signal generators (preferred).
• In-depth knowledge of wireless communication systems with hands-on experience in lab testing and characterization (preferred).
