Senior AI Engineer

Macmillan is one of the Big 5 Publishers with mission-critical systems running royalties, distribution, and the supply chain that books move through from manuscript to consumer. Those systems cannot be turned off. They also cannot stay as they are. The organization has committed to a multi-year modernization of its core technology platforms, the build of a Publishing Operating System that enables imprints to operate more efficiently, and the productionization of AI capabilities across the publishing lifecycle.
