Shindler began her career working for Granada Television, for whom she first came to prominence as a script editor on the drama series Cracker (1993). She then went on to work as assistant producer on the BBC's Our Friends in the North (1996) and producer on Hillsborough, a dramatised account of the 1989 football stadium disaster. All three starred actor Christopher Eccleston, who subsequently featured in several dramas for Red.
Red – named after the nickname of Shindler's favourite football team, Manchester United – was formed in 1998 and its first project, with Shindler producing, was writer Russell T Davies' gay drama serial Queer as Folk. Queer as Folk gave Red a reputation as producers of noteworthy drama, and they followed this off with subsequent series for Channel 4 such as Love in the 21st Century (1999) and Queer as Folk 2 (2000).
