Rae had remained at Leeds United despite announcing his exit earlier this year.
The out-of-contract Leeds United goalkeeper, Joshua Rae, played for Hibernian's development side on Tuesday evening - conceding and saving a penalty in a 4-3 defeat.
Rae announced his departure from Leeds at the start of the summer and has spent time with both Blackburn Rovers and Huddersfield Town since then.

Curiously, the 18-year-old was also part of the Whites' pre-season plans and travelled with Marcelo Bielsa's squad to Cagliari at the end of last month.
But he was named as one of two new additions ahead of Hibs' Tunnock's Caramel Wafer Challenge Cup tie with Elgin City, although unlike Dino Leddie, who has signed a two-year deal with the Edinburgh side, the length of Rae's stay has not been specified.
And that does little to clear up the confusion which currently surrounds the young Scot's situation.
Rae is already known to Hibernian's first-team manager, Paul Heckingbottom, who had a four-month spell in charge of Leeds last year.
Leeds are expected to recruit a goalkeeper of their own ahead of Thursday's transfer deadline for clubs in England's top two divisions, after selling Bailey Peacock-Farrell to Burnley.
