The 25-year-old actor, who portrayed young werewolf Tom McNair in the BBC Three supernatural drama, will play one of three leads in the ABC show.
According to Deadline, Socha will star as The Knave of Hearts in the show, which is penned by Once Upon a Time creators Eddy Kitsis and Adam Horowitz.
The story will be told from the point of view of Alice, as well as Socha's character - described as "a sardonic adventurer, a man of action, a loner and a heart-breaker" - and "exotic, soulful and optimistic" character Amahl.
The series will be set in a "pre-curse" Wonderland, based on the work by Lewis Carroll.
Being Human came to an end earlier this year after airing for five series.
