Jesco attracted international attention with his participation in the Nikolai Malko Competition for Young Conductors of the Danish National Symphony Orchestra in Copenhagen. Under the jury presidents Lorin Maazel and Sakari Oramo, he won Fifth Prize in 2012 and then both Third Prize and Audience Award in 2015.
Following an invitation by Emmanuel Krivine, he made his debut with the Orchestre National de France in 2016, resulting in immediate re-invitations in the same season and the appointment as Chief Assistant of the orchestra. His concerts at the "Chorégies d’Orange" festival and the "Festival Palazzetto Bru Zane Paris" in France, were broadcast by France Musique radio, ARTE Concert and medici.tv.
After three years as Chief Assistant Jesko returned to the Orchestre National de France as Guest Conductor and opened the 2020-2021 Radio France concert season at the Auditorium of the Maison de la Radio in Paris. In addition, he appeared for the last time as Conductor and Music Mediator at the Düs- seldorf Symphony Orchestra to make up for his farewell as Associate Conductor and Musical Director of the #IGNITION series, after a very successful 8 years.
In recent years Jesko Sirvend conducted among others the Robert Schumann Philharmonie Chemnitz and Staatsphilharmonie Rheinlfand Pfalz (Germany), Bern Symphonieorchester (Switzerland), Zagreb Philharmonic Orchestra (Croatia) and Tonkünstler Orchestra (Austria).
