About the Job

Requirements

  • A bachelor's degree is required.
  • Hands-on experience in wireless system design, integration, or bring-up is required.
  • Strong fundamentals in signal processing, communication theory, orthogonal frequency-division multiplexing systems, radio architectures, and analog/radio-frequency impairments are required, including understanding their impact on key system performance metrics.

Responsibilities

  • Drive bring-up, integration, and performance optimization of Wi-Fi physical-layer and radio systems for both pre-silicon and post-silicon stages.
  • Develop and integrate physical-layer features and calibration algorithms such as transmit power control, automatic gain control, transmitter signal strength indication, received signal strength indication, and interference mitigation.
  • Debug and root-cause system performance issues across radio-frequency domains, including impairments, calibration, and gain control, and digital physical-layer processing, including orthogonal frequency-division multiplexing, synchronization, channel estimation, and multiple-input multiple-output processing.
  • Collaborate closely with physical-layer system algorithm engineers, radio, radio-frequency integrated circuit, medium access control, and digital circuit designers to ensure end-to-end feature integration.
  • Support the transition from lab bring-up to robust firmware integration and product readiness.
  • Characterize radio-frequency and physical-layer performance and drive resolutions to ensure robust, high-quality product delivery.

Desired Qualifications

  • A Bachelor of Science in Electrical Engineering or Master of Science in Electrical Engineering and at least 3 years of relevant industry experience are preferred.
  • Experience, knowledge, and skills in wireless system design, integration, bring-up, and debugging of wireless physical-layer and radio-frequency systems on system-on-chip platforms are preferred.
  • A strong understanding of orthogonal frequency-division multiplexing and multiple-input multiple-output wireless systems across baseband and radio-frequency domains, with a solid foundation in related communication theory and signal processing, is preferred.
  • A strong understanding of wireless transceiver architectures, radio-frequency front ends, and related system-level tradeoffs is preferred.
  • Knowledge of analog/radio-frequency impairments, including DCOC, IQ imbalance, IP2, LOFT, and digital predistortion, and their calibration flows is preferred.
  • Proficiency with performance metrics such as error vector magnitude and sensitivity, and with impairment-mitigation strategies, is preferred.
  • Experience working across multi-radio coexistence environments is preferred.
  • Proficiency in using and understanding the theory of operation of laboratory equipment such as spectrum analyzers, signal generators, and power meters is preferred.
  • Experience with at least one of MATLAB, Python, shell scripting, or C/C++ is preferred.
  • Experience with automation infrastructure development, including traceability, repeatability, Git, continuous integration, databases, and reporting tools, is preferred.
  • Knowledge of wireless communication protocols, including 802.11a/b/g/n/ac/ax/be, LTE/WCDMA/GSM, or 802.11ad/ay, is preferred.
  • An advanced degree, such as a Master of Science or Doctor of Philosophy in Electrical Engineering, Computer Engineering, or another technical discipline, is preferred.
