In 1997, Michael joined the Jordan test team. In 1998 he was promoted to race engineer for Ralf Schumacher. When the German departed to go to Williams in 1999, Michael inherited Heinz-Harald Frentzen. His partnership with Frentzen was successful, resulting in a win at the French Grand Prix at Circuit de Nevers Magny-Cours, and then again at the Italian Grand Prix at Monza.
