[5] He has written for the TNT comedy-drama Men of a Certain Age (2010–2011) and HBO drama series Boardwalk Empire (2011), the latter of which earned him nominations for two Writers Guild of America Awards.
The musical premiered at The Public Theatre starring Adam Chanler-Berat, Andre de Shields, Brian Tyree Henry, and Rebecca Naomi Jones.
In 2024 Moses wrote the comedy-drama The Ally starring Josh Radnor as a Jewish college professor who deals with the moral quandary of being asked to sign a petition involving the denouncement of the state of Israel.
The production directed by Lila Neugebauer has received positive reviews with Sara Holdren of Vulture praising the performances and writing adding, "Pulsing ominously at the heart of The Ally is a question — a truly frightening one for artists, for scholars, for critics — about the more perilous face of nuance.
"[12] In a mixed review from Jesse Green of The New York Times he wrote that while "Moses’s play offers eloquent arguments on all sides of the Israeli-Palestinian conflict" it lacks certain narrative stakes adding, "I felt the need for more wisdom than craft".
