Sion has been a member of the board of directors since April 2020, and was previously CEO of Safran Electronics and Defense. He began his career in 1990 as a design engineer with the Société Européenne de Propulsion (SEP, now part of ArianeGroup) and later joined Safran Aircraft Engines as head of improvement initiatives.
“I welcome this appointment of Martin Sion whose background makes him very well placed to succeed André-Hubert Roussel as CEO of ArianeGroup,” said Eric Dalbiès, chairman.
