[1] Waché earned a doctorate in fluid dynamics from the National Polytechnic Institute of Lorraine, specialising in bio-mechanical engineering.
After graduating, he began working in 2001 for the global tyre manufacturer Michelin in their Formula One programme, and was an engineer that was responsible for the interaction between tyres and track conditions for Formula One cars.
[1] At the end of 2006, Michelin left Formula One as a tire supplier, which resulted in Waché being recruited by BMW Sauber as a performance engineer, working with tyres and suspension.
[2] In 2009, BMW announced that it would leave Formula One, which resulted in Waché replacing Loïc Serra as the head of vehicle performance for Sauber.
