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.
