No. If some they want someone for the Fortnite, they add this info to the title of job offer.
Check this for yourself, I count less than 10 offers specifically for this game.

Of course, some of the engine guys spend time on engine features required by Fortnite. Still, they merge a lot of good stuff from their projects into the vanilla engine.
Question is: how many engine systems wouldn’t exist at all if Epic wouldn’t create their own games? I doubt that we would have skeleton animation tools and AI if they wouldn’t develop big games that need these systems.
Seriously they don’t need all these engineers to create skins for Fortnite
