Job Summary
As a hands-on technical contributor you will be at the forefront of bring-up and system integration of advanced PHY and radio systems for state-of-the-art wireless SoCs. Your responsibilities will span over:- Transmit and receive chain bring-up tuning and performance optimization for both pre-silicon and post-silicon stages.- Develop and integrate PHY features and calibration algorithms (e.g. TPC AGC TSSI RSSI interference mitigation etc).- Development of chip control drivers and reference implementations in bring-up environments.- Close collaboration with PHY system Algorithm Engineers as well as Radio RFIC MAC and digital circuit designers.- Conduct pre-silicon emulation-based bringup integration and validation of the PHY system.- Supporting the transition from lab bring-up to robust firmware integration and product readiness.- Characterize performance analyze data root-cause system-level issues and ensure high product is a high-impact role requiring strong cross-functional coordination and deep technical insight into multicarrier wireless PHY/RF systems.
- BS and 10 years of relevant experience.
- Experience knowledge and skills on wireless system design integration bring up and debug of wireless PHY and RF systems on SoC platforms.
- Strong understanding of OFDM and MIMO-based wireless systems across both baseband and RF domains with a solid foundation in related communication theory and signal processing.
- Strong understanding of wireless transceiver architectures RF front-ends and related system-level tradeoffs.
- Knowledge of analog/RF impairments (e.g. DCOC IQ imbalance IP2 LOFT DPD) and their calibration flows.
- Proficiency in performance metrics such as EVM sensitivity and impairment mitigation strategies.
- Experience working across multi-radio coexistence environments.
- Proficiency using and understanding of the theory of operation of lab equipment (spectrum analyzer signal generator power meter).
- Experience with at least one of of the following: Matlab Python Shell scripting and/or C/C.
- Experience with automation infrastructure development (traceability repeatability) and related tools (GIT CI database reporting tools).
- Knowledge of existing wireless communication protocols: 802.11a/b/g/n/ac/ax/be LTE/WCDMA/GSM or 802.11ad/ay.
- Advanced degrees - MS or PhD in Electrical Engineer or Computer Engineering.
