This was easier than I expected, actually. Possibly that's just because my job's fairly easy to explain. Also, I had hints from reading other folks'.
I tell computers what their job is, and how to do their job.
The computers I work with are needed to make phone calls. They make sure that when you want to call someone, you call the right person, and that you can hear the person you call, and that they can hear you.
Sometimes I tell the computers how to do new things, like how to talk to new types of phone, or to ring a lot of phones at once when you call one of them. Other times the computers break, and I need to fix them.
