After receiving her doctorate in 1974, she taught at Cambridge University, where she worked as a research assistant to Arnold J. Toynbee. While at Cambridge, Caplan helped establish one of Britain's first courses in Women's Studies.^[1]

Caplan relocated to the United States, where she became visiting assistant professor at Columbia University in New York. She then moved to Bryn Mawr College in Pennsylvania, to become the Marjorie Walter Goodhart Professor of European History, a position she held until 2004.^[1]

In 2004 she returned to the UK to become a member of the History Department at the University of Oxford. She is currently a visiting professor at Birkbeck, University of London.

In 2011, Caplan became visiting fellow at the Max Planck Institute for the History of Science.

In addition to her position at Birkbeck, Caplan was appointed visiting professor of history for the 2013/2014 academic year at Gresham College.^[2] There she delivered a series of free public lectures in June 2014 collectively entitled "How do I know who you are? The History of Identity in Britain and Europe", following her research on individual identity.^[3]

Caplan regards her main research field to be Nazi Germany and most of her publications have been on this period of history. She also holds an academic interest in the history of women, sexuality and the history of individual identity and identity documents. She is currently working on the administration of identification in Nazi Germany, especially civil registration.^[1]

She has been a member of many editorial boards. She is one of the founding editors of Signum – The International Society for Mark Studies^[4] and she currently sits on the advisory board for German History,^[5] H-Net German,^[6] International Labor and Working Class History and L’Homme: Zeitschrift fur feministische Geschichtswissenschaft. She has also been Editor of History Workshop Journal and sat on the editorial board for American Historical Review, German History^[5] and Journal of Modern History.

In 2008, Caplan set up IdentiNet with Dr Edward Higgs from University of Essex. The aim is 'Documenting Individual Identity: Historical and Comparative Perspectives since 1500'. IdentiNet describes themselves as a 'network of academics from four continents, working to tell the story of individual identification within a long-term, international and comparative framework'. IdentiNet was supported by an International Networks grant from the Leverhulme Trust to the University of Oxford's Faculty of History.^[7]

Jane Caplan unexpectedly found herself thrust into the public spotlight due to her insightful commentary on the highly controversial topic of privatizing the Royal Mail. While walking down the streets in Oxford, Caplan was stopped by a reporter who sought her opinion on the matter. Unfazed by the unexpected encounter, Caplan passionately delved into an impromptu rant, eloquently articulating her views and raising critical points. Her unscripted outpouring was captured on camera and shared on YouTube.^[8]
