She trained at the Walden Theatre Conservatory program, and later at New York City's Juilliard School (Drama Division Group 31: 1998–2002).

Before graduation, she was cast in the 2002 Broadway revival of Arthur Miller's The Crucible starring Liam Neeson and Laura Linney.Carpenter first attracted critical attention for her performance in The Exorcism of Emily Rose. She took home the 2006 MTV Movie Award for "Best Frightened Performance", and received a "Hollywood Life Breakthrough Award". She was named "Breakout Performer" at the 2006 Scream Awards.

Carpenter played the role of Debra Morgan in the Showtime crime drama television series Dexter, which premiered October 1, 2006. Her portrayal of the title character's adoptive sister impressed a number of critics, with Australian journalist Jack Marx describing her portrayal of "cool and clumsy" Debra as "so perfect that many viewers appear to have mistaken the character's flaws for the actor's."

In 2008, she starred in Quarantine, an American remake of the 2007 Spanish horror film Rec, about a deadly zombie virus outbreak in an apartment complex.

In 2011, she starred in the off-Broadway play Gruesome Playground Injuries at Second Stage Theatre and had a guest appearance on the CBS drama The Good Wife.

In January 2014, it was announced that Carpenter would star in a new ABC drama Sea of Fire, playing FBI Agent Leah Pierce. However, the show was not picked up as a series. In August 2014, it was announced that she would provide the voice of Juli Kidman in the survival horror video game The Evil Within, marking her first video game appearance. The game was released in October 2014, and Carpenter provided voicework for two of The Evil Within's DLC chapters, "The Assignment" and "The Consequence", which featured Juli Kidman as the playable protagonist. However, Carpenter did not reprise the role in the game's sequel, The Evil Within 2, and her character was recast.

In early 2015, Carpenter was cast in the CBS drama series Limitless in which she co-starred with Jake McDorman.

On July 13, 2021, Showtime confirmed that Carpenter would reprise her role of Debra Morgan in a 10-episode limited series, Dexter: New Blood, with Clyde Phillips returning as showrunner. The series premiered on November 7, 2021.
