[2] Young began his professional career in 2004 working as a junior sound designer in the centralised audio department of Sony London Studio.

[2][5] He has described this period as "an apprenticeship" and a "baptism by fire"[6] which stood him in good stead for his future game audio work.

[4] Young left Sony in 2007 and joined startup video game developer Media Molecule to establish their audio department and "make LittleBigPlanet sound awesome".

[4] LittleBigPlanet's audio aesthetic: minimal, playful yet endlessly customizable building blocks of sound and music that support, underpin and emphasize the playfulness inherent in the game's unique art direction, character design and game design structure.

[9][10] Young and fellow composer Mat Clark won the GANG awards for Best Original Instrumental (for "The Gardens") and Best Interactive Score.

[13] Tearaway's folk-infused soundtrack received a 2014 British Academy Video Games Award nomination for Original Music[14] and is notable for its hand-made aesthetic, being written and performed entirely by Young and co-composer Brian D'Oliveira.
