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, UWB, NFC).
Description
You will be responsible for assessing platform-level multi-radio coexistence performance, including:
- Working with cross-functional partners to assess the multi-radio coexistence performance impact to the end user.
- Working with wireless software partners to design the software mitigation scheme, assess the trade-offs and implementation path.
- Bring-up device-under-test, setups and test procedures for multi-radio coexistence performance studies.
- Analyze wireless logs to understand field usage patterns and incorporate these learnings to perform controlled bench performance studies for multi-radio coexistence.
- Proposing HW/SW 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.
- Collaborating with cross-functional partners for circuit-level, system-level simulations to understand risk areas and root cause issues.
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 line-up.
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.
Excellent communication written and verbal skills.
