- Proficient working in the lab with RF test equipment, including vector network analyzers, spectrum analyzers, signal generators, power meters, oscilloscopes, and logic analyzers
- Strong grasp of RF fundamentals: S-parameters, impedance matching, gain, compression, noise figure, phase noise, intermodulation, and link budgets
- Working knowledge of calibration, de-embedding, fixture removal, and the sources of measurement error and how to mitigate them
- Proficiency with programming and automation/scripting languages or ability to quickly learn them (i.e. Python, C++, MATLAB) for instrument control and data analysis, and navigating Linux terminals and file systems
- Familiarity with design tools for schematic capture and reading RF/analog schematics
- Strong technical documentation skills, including report writing and test result documentation and storage
- Familiarity with software defined radios
- Experience analyzing circuits and developing functional test plans
- Board rework experience, specifically surface-mount soldering & hot-air rework
