About the role
- Develop and implement innovative RF desense solutions (hardware and software) to ensure robust system performance
- Collaborate with RF, antenna, electrical, mechanical, and software teams to integrate RF systems into Spectacles products and ensure compliance with performance standards
- Conduct rigorous lab and OTA testing of RF systems, perform sensitivity and coexistence testing (LTE, 5G, WiFi, GNSS, Bluetooth, etc.), and validate performance against industry standards
- Characterize desense caused by internal aggressors (CPU, memory, power converters, displays, etc.) and external interferers. Trace root causes using probes, shielding tests, grounding checks, and layout reviews
- Identify system performance bottlenecks (impacts) due to antenna, RF board, assembly dependencies, multi-radio operation, etc.
- Develop and execute coexistence test plans and generate validation reports
- Author clear and comprehensive documentation
Requirements
- Bachelor’s degree in a related technical field such as electrical engineering, computer science, or physics or equivalent years of experience
- 10+ years of experience in electrical, RF, and/or computer engineering
- Strong RF, antenna, EMI, EMC, and coexistence engineering fundamentals
- Knowledge of wireless communication standards including WiFi, BT, BLE, GPS, 4G LTE, 5G, etc
- Knowledge of board level design strategies for desense and EMI minimization, signal integrity, and isolation
- Experience working with systems that include high-speed digital interfaces such as MIPI CSI / DSI, PCIe, SDIO / eMMC, UFS, etc
- Proven ability to use common RF and electrical test equipment such as oscilloscopes, spectrum analyzers, network analyzers, and power supplies
- Understanding of RF PCB design, associated constraints, impedance matching, and filter tuning
- Proficiency with RF simulation/design tools (e.g., CST Microwave Studio, Keysight ADS, XFdtd, etc)
- Excellent process development and documentation skills
