As an Audio/SFX editor, your role is to create the sound effects for the show while also piecing the voices and music together, essentially editing all the audio for the show to feel as seamless as possible.

Side note: When applying for this position, you can clarify whether you are okay with doing both or just one or the other. Being able to do both would have better chances of being picked, but multiple people are needed for this position so both abilities are not required to apply.
