Hirsch is most known for creating the series Gravity Falls for the Disney Channel. He provided the voice of Grunkle Stan, Soos, Old Man McGucket and Bill Cipher, as well as many other minor characters featured throughout the show.
Hirsch first started out as a writer and storyboard artist for The Marvelous Misadventures of Flapjack, where he worked alongside and befriended fellow animators J. G. Quintel (who would go on to create Regular Show) and Pendleton Ward (who would go on to create Adventure Time).
Hirsch later moved on to be the writer, storyboard artist and creative consultant for Fish Hooks, which he also developed for television alongside Maxwell Atoms, where he portrays Clamantha, her father, Fumble, one of the fish police and a Ferret.

It was revealed on August 16, 2016 that Hirsch is now co-writing the new live-action Pokémon movie Detective Pikachu alongside Guardians of the Galaxy and Captain Marvel writer Nicole Perlman.
Gravity Falls was inspired by Hirsch's own childhood experiences with his twin sister during their summer vacations. He places many of his real-life experiences in the show, like living in Piedmont and trick-or-treating with his sister as kids. Mabel Pines, one of the lead characters of Gravity Falls, was inspired by his twin sister, Ariel Hirsch. In the series Mabel gets a pet pig, just like his sister had always wanted when she was a kid.
Hirsch is a graduate of Piedmont High School. In 2002, as a junior, he won the high school's annual bird-calling contest and appeared on the Late Show with David Letterman, demonstrating the call of the great blue heron.
