RF Engineer
Apply physics principles to design reliable systems and products.
What is a RF Engineer?
RF Engineers specialize in the design, development, testing, and troubleshooting of electronic systems that operate at radio frequencies (RF), typically from 3 kHz to 300 GHz. They work with antennas, transmitters, receivers, and integrated circuits to ensure efficient and reliable wireless communication.
Most days are indoor bench work: setting up RF measurement rigs, calibrating instruments, running controlled tests, and maintaining experiment databases. You spend time developing statistical models and simulations to extract signal features, preparing technical reports for collaborators and regulators, and adapting hardware or software for clinical use. Meetings with life scientists and face-to-face troubleshooting punctuate the day.
