Ritter was scouted by a modeling agent at the age of 15 at her local shopping center, the Wyoming Valley Mall in Wilkes-Barre, Pennsylvania during a modeling event. In a Philadelphia Style magazine interview, she said she was "tall, gawky, awkward, and really, really skinny." While in high school, she traveled to New York City and Philadelphia to model. She then signed with the Elite Model Management agency and Wilhelmina Models, Ritter moved to New York and subsequently established an international modeling career, appearing in print ads and on television. She did magazine, catalog, and runway work in Tokyo, New York City, Paris, and Milan.

Her "outgoing and bubbly and funny" performance personality had entertained casting personnel, she told Philadelphia Style.

The series was not picked up by the network for the 2009–10 season, by which time Ritter appeared as Jane Margolis in the second season of Breaking Bad. The role of Jane was her breakthrough, at which Ritter expressed surprise on People's Couch Surfing program: "Talk about (a) cult following, this show really is the gift that keeps on giving."
