About the role

Wireless Systems Integration Engineer role within Apple's Wireless Connectivity team, focused on integration, bring-up, and tuning of physical layer/RF systems for next-generation wireless SoCs from pre-silicon to product launch, collaborating across PHY, RF, digital, MAC, and firmware teams to ensure end-to-end wireless performance.

Responsibilities

  • Drive Bring-up, integration, and performance optimization of Wi-Fi PHY and Radio Systems for both pre-silicon and post-silicon stages.
  • Develop and integrate PHY features and calibration algorithms such as TPC, AGC, TSSI, RSSI, and interference mitigation.
  • Debug and root-cause system performance issues across RF domains (impairments, calibration, gain control) and digital PHY processing (OFDM, synchronization, channel estimation, MIMO).
  • Collaborate closely with PHY system Algorithm Engineers as well as Radio, RFIC, MAC and digital circuit designers to ensure end-to-end feature integration.
  • Supporting the transition from lab bring-up to robust firmware integration and product readiness.
  • Characterize RF/PHY performance, and drive resolutions to ensure robust, high-quality product delivery.

Qualifications

  • BS and a minimum of 10 years relevant industry experience
  • Hands on experience in wireless system design, integration, or bring-up.
  • Strong fundamentals in signal processing, communication theory, OFDM systems, radio architectures, and analog/RF impairments, with understanding of their impact on key system performance metrics.
  • Preferred MSEE or PHD with 3+ years relevant industry 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 such as spectrum analyzer, signal generator, power meter.
  • Experience with at least one of the following - Matlab, Python, Shell scripting and/or C/C++.
  • Experience with automation infrastructure development including 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, Computer Engineering or other technical disciplines
