She began her career in production at Ciné sud Promotion. She started Parati Films with the goal of creating a cinematic exchange program, most notably between France and the countries of Latin America. The dynamism of the four areas of Parati Films – event organization, subtitle & translation, production and teaching production management – has resulted in collaborations with countless professionals from the world of cinema and international festivals. One such example is the Cannes Film Festival, where from 2011 till 2021 Parati has been the official partner of the Institut Francais and Séverine is in charge of the selection of projects and the coordination of the La Fabrique des Cinémas du Monde program. She also teaches International Co-production at the EICTV (Cuba) and Film Production at the master level in Paris. Parati has just produced two short films: Salvo, a documentary by Séverine Roinssard and Julio Lisboa (France) and Bolero Rojo by Angel Molina (Paraguay) and is co-producer of projects in development: Corações Solitários, by Caru Alvez (Brazil), El Lugar y la Esperanza by Ariagna Fujado (doc, Cuba), and Neon by Angel Molina (Paraguay). Séverine is focusing part of her work also on Crok Cine – the Education and the Image Project – focus on social mix in France, using auteur cinema as a tool.
