His first musical steps were at a young age when he started taking classical guitar lessons. His career as a musician and producer began in 1983, as one of the founding members of the synthpop band Camouflage. In the 1990s, Maile founded with Marcus Meyn the music publishing company, Areu Areu. During this time, he met the music producer Mathias Willvonseder. They formed a long-term partnership, resulting in numerous commercials and films, which were often awarded prizes at festivals. He is also a member of the Composers' Collective Gutleut, where he met composer and arranger Torsten Kamps, and the two began working closely together. During this time, Maile started to develop a desire to compose for films and approached producer Christian Becker. Maile finally began composing for films in 2006 when he did the music for a short film called Basti. Maile was then hired by Becker to create the score as well as a few original songs for the teen-thriller The Wave. The film was a hit among both critics and viewers. He also made music for the popular film Vorstadtkrokodile, and its sequels Crocodiles Strikes Back and Crocodiles: All for One. Maile went on to have a good working relationship with Christian Becker and The Wave director Dennis Gansel and composed the music for "We Are the Night", which was nominated for German Film Prize (the German Oscars) in 2011. In 2017 Maile won the "Deutscher Fernsehpreis 2017", Best Music for "Winnetou - Der Mythos lebt".
