In this technical role, you will be part of a silicon design group responsible for system integration, bringup and characterization of state-of-the-art wireless SoC products from conception to production.
Core responsibilities include, but are not limited to, the following:Lead PHY hardware validation efforts on emulation and FPGA platforms ; Develop and maintain Python/Matlab based Pre/Post-silicon validation and debug environments ; Design and implement optimal calibration algorithms in Python/Matlab simulation environment, simulate and bench mark performance ; Implement on-chip calibration algorithms with HW/SW constraints for factory tuning and real time operation ; Bringup, validate, and tune Phy/Radio systems on emulation, simulation and real silicon platforms to achieve optimal performance ; Work alongside PHY, MAC, FW, RFIC and digital circuit designers on efficient implementation of DSP algorithms ; Develop and implement test plans, collect and analyze test results, identify and debug issues.
- BS and a minimum of 10 years relevant industry experience.
- Hands-on experience with chip bringup, tuning transmitter and receiver chain performance.
- In-depth knowledge in communication theory, OFDM systems, RF system architecture and signal processing algorithms (such as timing recovery, signal estimation and detection, automatic gain control, RF impairment estimation and correction, channel estimation, equalization, coexistence, interference mitigation etc.).
- Experience designing algorithms for calibration, pre-equalization, cancellation, and/or digital pre-distortion techniques.
- Experience with Python, Matlab, or C/C++ implementation.
- Hands-on experience using wireless test lab equipment (spectrum analyzer, signal generator, network analyzer, power meter), along with a solid understanding of the underlying theory for communication system debugging.
- Knowledge of wireless communication protocols like 802.11a/b/g/n/ac/ax/bc, 802.11ad/ay or LTE.
- Experience with pre-silicon validation using emulation and FPGA prototyping tools and methodologies.
- Excellent analytical and debug skills, with an ability to debug hardware issues within emulation environment.
- Experience building test automation and verification flow development with scripting languages such as Python.
