An RF (Radio Frequency) Engineer is a specialist who focuses on radio frequency technology and electromagnetic fields. Their main role involves designing, implementing, maintaining, and enhancing wireless communication systems that operate using radio frequency signals. These systems encompass diverse wireless technologies like cellular networks, Wi-Fi, Bluetooth, satellite communication, radar systems, and more.

RF Engineers work on transmitting and receiving radio waves, aiming to ensure the efficient operation of wireless communication systems. They design antennas, transmitters, receivers, and other RF components, striving to optimise signal strength, coverage, and reliability while minimising interference and signal degradation. Their responsibilities often include conducting site surveys, performing studies on radio propagation, analysing and mitigating interference, optimizing network performance, troubleshooting issues, and ensuring compliance with regulatory standards and specifications.
