Job Description


A globally leading consumer device company based in Cupertino, CA is seeking RF Hardware Engineer to join their team. This individual will work on overall system performance of multi-radio coexistence for various wireless technologies (e.g., Cellular, Wi-Fi, BT, GPS, UWB, NFC).
Job Responsibilities:

  • Partner cross-functionally to assess multi-radio coexistence performance and its impact on the end-user experience across platforms.
  • Define product-level coexistence performance specifications, use cases, test methodologies, and key performance metrics.
  • Bring up devices under test and develop bench setups, mockups, experiments, and test procedures for coexistence validation.
  • Define and execute validation and characterization test plans, track progress, analyze results, and communicate data-driven insights to cross-functional partners and leadership.
  • Collect and analyze performance data and wireless logs across RF parameters to characterize coexistence performance and derive hardware specifications.
  • Collaborate with analytics and field teams to understand usage patterns, assess the prevalence of coexistence issues, and demonstrate end-user impact through field-log analysis and controlled experiments.
  • Partner with cross-functional teams on circuit- and system-level simulations to identify risk areas and determine the root cause of coexistence issues.
  • Monitor hardware performance throughout development builds and recommend hardware, software, or process changes while considering design constraints and implementation trade-offs.
  • Collaborate with wireless software teams to design and implement mitigation policies based on bench, field, and factory hardware data.
  • Lead cross-functional efforts to establish software mitigation strategies for current and future technology platforms.


Minimum Qualifications:
• Bachelor's degree in electrical engineering with 10+ years relevant work experience. 
• Experience with at least one radio of Cellular, GPS, Bluetooth, Wi-Fi, Thread, NFC, and UWB.
• Knowledge of RF component characteristics and experience using lab equipment including spectrum analyzer, network analyzer, signal generator, oscilloscopes, call box.
• Knowledge of wireless architectures including front-end, antenna sharing, link budget lineup.
Preferred Qualifications:
• Master's degree in electrical engineering with 10+ years relevant work experience.
• Experience debugging and performing RF measurements at the conducted & radiated level.
• Experience on co-existence performance benchmark, impact analysis, software mitigation scheme, MAC/PHY and throughput measurement and debug.
• Experience working with chipset teams to define RF/wireless system-level requirements and influence chipset architecture or design decisions.
• Familiarity with wireless protocol stack at the RF, PHY & MAC layers.
Type: Contract
Duration: 12 months with extension
Work Location: Cupertino, CA (hybrid)
Pay range: $85.00 - $100.00 ph (DOE)
