About The Position

Snap Inc. is a technology company focused on improving how people live and communicate through its camera-centric platform. The company operates Snapchat, Specs Inc. (developing advanced eyewear and developer tools for augmented reality), Bitmoji, and Saturn. This role is within the Spectacles team, seeking a Desense Engineer to develop and implement innovative RF desense solutions (hardware and software) to ensure robust system performance. The engineer will collaborate with cross-functional teams, conduct rigorous testing, characterize desense issues, identify performance bottlenecks, and develop coexistence test plans. The role also involves authoring clear and comprehensive documentation.

Requirements

• 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
• Bachelor’s degree in a related technical field such as electrical engineering, computer science, or physics or equivalent years of experience
• Ability to travel including domestic and international (up to 15%)
• 10+ years of experience in electrical, RF, and/or computer engineering

Nice To Haves

• Master's or PhD in Wireless, Electromagnetics, Electrical engineering or related field
• Knowledge of ESD principles for consumer electronics

Responsibilities

• 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

Benefits

• Paid parental leave
• Comprehensive medical coverage
• Emotional and mental health support programs
• Compensation packages that let you share in Snap’s long-term success (equity in the form of RSUs)
