As an RF test engineer, you assess the functionality of devices that transmit or receive radio frequencies in manufacturing or research and development environments. Your job duties include using spectrum analyzers, vector network analyzers, signal generators, battery emulators, and other testing equipment, debugging issues that arise, and analyzing test data. A career as an RF test engineer requires you have some formal qualifications and post-secondary education, generally a bachelor’s degree in electrical engineering and experience with test instrumentation and equipment. You need strong math skills and familiarity with computer-aided design (CAD), Unix, MatLab, LabView, and C++ programming.
