While going to school, Melissa performed stand-up comedy around Manhattan, and soon made a name for herself on the NYC comedy scene. Her one-woman show, "The Miss Education of Jenna Bush", in which she portrayed Jenna Bush, the former President's daughter, garnered critical acclaim and played to sold-out audiences (Outstanding Solo Show and TheaterMania's Audience Favorite Award—New York International Fringe Festival/HBO's US Comedy Arts Festival).
Some of Rauch's early work was as a regular contributor to VH1's Best Week Ever television show.
In 2009, Rauch began playing the recurring role of Bernadette Rostenkowski, a co-worker of Penny who began to date Howard Wolowitz, in the third season of TV's The Big Bang Theory. The following season her character became Howard's fiancée and Rauch was promoted to a series regular. The characters married in the season five finale.

Rauch is married to writer Winston Rauch (né Beigel), who collaborated with her on The Miss Education of Jenna Bush and other projects. Rauch modeled the voices of Bernadette after her parents: the "sweet, high-pitched purr" is modeled after her mother, while the "eerie, haranguing imitation" of Mrs. Wolowitz is modeled after her father. Both are "very different" from Rauch's real voice.
