About the role

Role focused on system integration and characterization of state-of-the-art wireless SoCs, bringing up PHY/radio on first-silicon, optimizing performance through calibration and test automation, and driving silicon maturity toward mass production.

Responsibilities

  • Bring up, integrate, and tune PHY and radio systems on first-silicon wireless SoCs.
  • Characterize and validate PHY/RF performance across operating modes and conditions.
  • Debug and root-cause system-level issues spanning PHY algorithms, RF circuits, firmware, and test setup.
  • Work closely with cross-functional teams—including PHY algorithm, RF design, digital, MAC, and firmware—to ensure seamless system integration and performance optimization.
  • Develop and automate test and characterization workflows to accelerate silicon evaluation and regression.
  • Analyze results to identify performance bottlenecks, drive improvements in calibration algorithms (e.g., IQ imbalance, LO leakage, TSSI, Power Control), and ensure robust performance across process and temperature corners.
  • Document findings, communicate results, and drive silicon maturity through iterative bring-up cycles until mass production readiness.

Qualifications

  • BS and a minimum of 3-10 years relevant industry experience
  • Strong fundamentals in RF/PHY systems, signal processing, communication theory, and analog impairments — with practical expertise in their application to OFDM-based transceivers.
  • Preferred MSEE or PHD degree with some relevant experience
  • Knowledge in existing wireless communication protocols: 802.11a/b/g/n/ac/ax/be, LTE/WCDMA/GSM, or 802.11ad/ay.
  • Understanding communication theory and key Tx/Rx metrics like EVM and sensitivity.
  • Experience bringing up radio calibration algorithms (such as Power Control, IQ imbalance, LO Leakage, TSSI or others).
  • Experience in system bring-up, integration, characterization, and debug of real wireless silicon in a lab.
  • Experience using and understanding the theory of operation of wireless/RF test equipment such as signal analyzer, signal generator, and spectrum analyzer.
  • Experience developing test automation including equipment drivers, debug tools, automation scripts, database interfaces, and reporting tools.
  • Experience with Python, Matlab, Perl, C/C++, or C#.
  • Experience with automation infrastructure development (traceability, repeatability) and related tools (GIT, CI, database, reporting tools).
  • Preferred advanced degrees MS or Ph.D in Electrical Engineer or Computer Engineering.
