Rossi began his career in the United States before moving to Europe as a teenager to pursue a career in Formula One. He won four races in the developmental GP2 Series, one for EQ8 Caterham Racing in 2013 and three more for Racing Engineering in 2015. After serving as a test and development driver for Caterham F1 and Marussia F1, Rossi made his Formula One debut in 2015 for the renamed Manor Marussia F1 Team, driving in five Grand Prix races, including his home Grand Prix in the United States, where he finished a season-best twelfth.
