Sr RF Characterization Engineer - San Jose, CA, United States
$115,600 - $150,500 USD yearly
Originally posted 3 September 2026 by the employer.
This role focuses on the characterization and design validation of RF Front-End Modules (RF FEMs).
About the role
As a Senior RF Test Development Engineer, you will own the design, implementation, and scaling of automated test Racks and Benches used for Characterization and Design Validation Testing (DVT) of complex, highly integrated RF Front-End Modules (RF FEMs).
What you'll do
- Partner with RF IC and Hardware Design Engineers to align test methodologies with design simulation models.
- Design, enhance, and maintain highly scalable, automated RF test scripts and software environments (primarily VB.net, Python, C#, or LabVIEW).
- Lead lab bring-up, DVT, and comprehensive root-cause debugging of mobile prototype FEMs containing Power Amplifiers (PAs), Low Noise Amplifiers (LNAs), switches, MIPI RFFE programing, and integrated filters.
- Analyze and plot performance results and share with design teams.
- Mentor Technicians on new software and laboratory equipment.
What you'll need
- BSEE with an emphasis on RF/Microwave systems.
- 5+ years of active industry experience in mobile cellular/wireless RF validation.
- Demonstrated proficiency programming for instrument communication and measurements, including with VB.net, Python or C++.
- Mastery of lab infrastructure: Vector Network Analyzers (VNAs), Spectrum Analyzers, Vector Signal Generators (VSGs), power meters, and MIPI RFFE protocol analyzers.
- Strong working knowledge of 3GPP standards (LTE, 5G NR, FR1/FR2) and/or Wi-Fi architecture.
Skills: RF validation, VB.net, Python, C#, LabVIEW, VNA, Spectrum Analyzer
