An Audio or Sound Engineer, much as the name implies, is tasked with the management of the technical aspects of sound in terms of media, whether it be live streaming or pre-recorded broadcasting.
They are generally meant to set up audio equipment and work with producers, directors, and musicians to optimize the use of this technology and understand the problems that need solving and the perimeters of the project. The Engineer also alters and edits audio files as necessary and fixes issues as they come up.
A person seeking work as a Sound Engineer generally needs to have only a high school diploma, though a university degree and certification in a relevant subject may be preferred or even necessary. Previous work experience is often needed in positions similar to this one or even those assisting Sound Engineers. Creativity, understanding of microphones and other audio equipment, and communication skills are also important.
