Born in Santiago de Chile, Vinet began ballet training at Escuela de Ballet del Teatro Muncipal de Santiago. After two years under full scholarship he moved to Houston, Texas to finish his training at Ben Stevenson Houston Ballet Academy.

 
In 2009 he joined the Houston Ballet and in 2010 the San Francisco Ballet. Vinet danced principal roles by renowned choreographers including Marcia Haydée, Kenneth Macmillan, William Forsythe, Christopher Wheeldon, Helgi Tomasson, Stanton Welch, Mark Morris, Ben Stevenson, Demis Volpi, Val Caniparoli, John Cranko, among others. He has been invited to dance at international ballet galas in England, Denmark, China, Dominican Republic, Uruguay, Indonesia, Russia, Mexico, Argentina, Brazil, Ethiopia, Colombia, Japan, Australia, the United States, Hungary, Canada, Peru, Paraguay and Switzerland – where he was one of the winners and an apprenticeship recipient at the 2009 Prix de Lausanne. Vinet also was a recipient of the Premio Jovenes Líderes del diario El Mercurio (2009) – an award to Chilean artists, presented by the ambassador of Chile in the United States. Vinet appeared as a special guest dancer at the 2009 Grammy Awards and holds a parallel career as a model, appearing in campaigns for brands like Armani, Burberry,
Newman and Dolce and Gabbana, and has been featured in Vogue. In 2017 Vinet was the artistic director and creator of the first international ballet gala to be presented at the emblematic theater in Chile Teatro Oriente. 

In 2018 he was mentioned in Dance Australia as one of the best performances of the night during the premiere of FORTE in Melbourne, Australia and in 2020 he directed and founded the digital show interMission, a production filmed in three continents gathering some of ballet’s biggest stars all coming together digitally to raise funds for the international charity Save The Children.

Most recently, Vinet was honored to be a 2020 Prix de Lausanne competition jurist in Switzerland and in 2022 for Youth American Grand Prix, Danza Activa in Panama and Icon Dance awards, being the youngest person in the history of these prestigious competitions to be invited to join the panel of judges. 

Sebastian is currently an international principal guest dancer, performing at several international ballet galas and dance events as well as teaching masterclasses at the top ballet schools in the world and companies around the world like: ABT, Les Ballet de Monte Carlo, Ballet Nacional Sodre, Ballet de Santiago, San Francisco Ballet, Compañía Nacional de Danza, among others. These teaching experiences have inspired him to create a scholarship program called Bailarines del Manana, awarding over $100,000 USD in scholarships in Chile and Peru.
