Working steadily in film and television for the last decade, Posey is also the frontman of the band 'Lost In Kostko', in which he sings and plays guitar. One of his first, and one of his most unrecognized roles was Maid in Manhattan, in which he co-starred with Jennifer Lopez.

In his breakout role, Posey was cast as the lead in the MTV television series of Teen Wolf (a re-imagining of the 1985 film of the same name), as the soft-spoken Scott, a high school student bitten by a werewolf, who has to keep his secret from his loved ones and keep them safe from impending dangers. Because of this role, he has received many comparisons to Taylor Lautner of The Twilight Saga. Posey has known Lautner for a number of years, and actually finds the similarities laughable.^{[citation needed]} He jokes about when a new kid moved into his town who had a similar name to him, and that Lautner later started dating a girl that Tyler liked. He, as a matter of fact, auditioned for, and was the runner up for the role of Jacob Black in Twilight, that later went to Lautner.^{[citation needed]}
