No. At the time of the Harry Potter story, he was a death eater in the past, but in the meantime he repented, and (despite his unpleasant character!) worked faithfully for Dumbledore, and the Order of the Phoenix.

Severus was pretending to be a death eater, spying on the Order of the Phoenix. When he was actually a Order of the Phoenix member, pretending to be a death eater spying on the Order. He risked his life for years to try and save Lily and then Harry.
They don't use this word before the fourth book, but of course Lucius Malfoy, Peter Pettigrew and Severus Snape (who appear in books 1-3) are indeed Death-Eaters. (Severus Snape was a death eater, then changed sides.)
