• Familiarity with test automation tools, data acquisition systems, and scripting (Python, LabVIEW, MATLAB, C/C++, etc.).
• Knowledge of configuration management tools and processes.
• Working knowledge of RF test equipment (spectrum analyzers, network analyzers, signal generators, oscilloscopes).
• Ability to review, interpret, and approve RF test data and results.
• Familiarity or hands-on experience with phased array testing and/or ESA testing.
