Rosenfeld has been involved in the food and beverage industry for about 30 years. Her first job was at Dancer Fitzgerald Sample advertising agency in New York City; she later joined General Foods in consumer research.

In 2004, Rosenfeld was appointed chairwoman and CEO of Frito-Lay, a division of PepsiCo, where she focused on product promotion.

Rosenfeld was appointed CEO of Kraft Foods In June 2006. She joined General Foods which later became a part of Kraft. Among her many accomplishments at Kraft, she led the restructuring and turnaround of key business in the US, Canada and Moscow. She is active in a number of industry and community organisations, including the Economic Club of Chicago. She was appointed to the additional post of chairman in March 2007, following Altria Group's spin-off of Kraft.

In 2008, she was named sixth on The Wall Street Journal's "50 Women to Watch" list. Rosenfeld has been listed multiple times as one of the 100 most powerful women in the world by Forbes where she was ranked at 15th, just behind Oprah Winfrey, in 2014.

In August 2011, Kraft said it planned to split into two publicly traded companies, one focusing on its international snack brands like Trident gum and Oreo cookies and the other on its North American groceries business that includes Maxwell House coffee and Oscar Mayer meats.

On December 5, 2011, Kraft announced that Rosenfeld would stay on as chairman of the $31 billion global snacking company, which would be called Mondelēz International, Inc. Tony Vernon, the president of Kraft Foods North America, would become CEO of the $17 billion North American grocery business, which would keep the Kraft Foods name.

Mondelez announced in August 2017 that Dirk Van de Put would replace Rosenfeld as CEO of the company following her retirement in November 2017.

During campaigns for the 2016 US presidential election, Mondelēz and Rosenfeld were criticized by Republican candidate Donald Trump and Democratic candidates Hillary Clinton and Bernie Sanders for outsourcing approximately 600 U.S. jobs from Chicago to Salinas, Mexico, prompting the Oreo Boycott. Worker pickets have also taken place at various events Rosenfeld has attended, in addition to outside her own home.
