Our RF Systems Engineering team is looking for a passionate, self-motivated individual to work on overall system performance of multi-radio coexistence for various wireless technologies (e.g., Cellular, Wi-Fi, BT, GPS, NFC, etc.).

You will be responsible for assessing platform-level multi-radio coexistence performance, including:

– Performing HW failure analysis at the RF/wireless system level to understand low margin or failing behaviors making use of hands-on experimental modifications to hardware.
– Proposing design and process changes for multi-radio coexistence issues considering design constraints and align with cross-functional partners on trade-offs and implementation path.
– Execution of validation & characterization test plans to meet multi-radio coexistence performance targets.
– Tracking validation status, analyze results and communicate insight from data.
– Working with cross-functional partners to assess the multi-radio coexistence user impact.
– Working with wireless software partners to design the software mitigation scheme, assess the trade-offs and implementation path.
– Collaborating with cross-functional partners for circuit-level, system-level simulations to understand risk areas and root cause issues.

BS with 3+ years relevant experience required.Experience on 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 and oscilloscopes.Knowledge of wireless architectures including front-end, antenna sharing, link budget line-up, etc.
