Alongside Peter Sellars, he understands that “creation can be politically committed, speaks of major societal topics while taking artistic risks.” In 1999, he joined the team of Théâtre Royal Flamand (KVS) in Brussels. In 2001, he was appointed head of this repertoire theatre which, during its refurbishment, moved to Molenbeek, a multicultural neighbourhood of Brussels. He reinvented the mission of the Flemish institution by orienting it towards contemporary, multilingual and multidisciplinary creation. In 2004, the KVS returned to its historical birthplace with a renewed audience and a project deeply connected to civic dialogue open to the city and the World. Under his influence, in fifteen years, the KVS became a key cultural organisation for Belgian and international creation, strongly linked to creation in Africa and the South.
In May 2015, he was appointed director of the Festival de Marseille. He took up his post in September 2015 before becoming the general director on 31 July 2016.
For the 2017, 2018 and 2019 editions of the Festival de Marseille, he presented the new creations by Brett Bailey, Bruno Beltrao, Rimini Protokoll, Serge Aimé Coulibaly, Fabrizio Cassol & Alain Platel , Nacera Belaza, Wael shawky, Latifa Laabissi and Boyzie Cekwana, amongst others.
In 2013, Jan Goossens received the Citizenship Award of the Foundation P&V which rewards the leading figures “committed in an exemplary way for an open, democratic and tolerant society”. He was given the title of Chevalier de l’Ordre des Arts et des Lettres for the Spring 2016 promotion by the French Ministry of culture.
