Orient and Embleton went their separate ways after the club’s 3-1 loss to Tranmere Rovers on Saturday. The loss left Orient in 14th place in the league eight points adrift of the play-off places.
Nigel Travis, Leyton Orient’s chairman confirmed then that McAnuff would fill in until further notice.
"Jobi is a natural leader and someone we feel has got what it takes to make a top-class manager," he told Skysports.
The 39-year-old McAnuff made 166 appearances for Leyton Orient over two spells – from 2014-2016 and from 2017.
McAnuff made 32 international appearances for Jamaica between 2002 and 2016.
The 31-year-old midfielder, who spent the final year of his career as player-coach for EFL League Two outfit Leyton Orient, played his final game against Carlise, on May 1, which ended in a 3-2 home defeat for Orient.
McAnuff, who also played 32 games for the Jamaica national team, believes the time had simply come to hang up his boots.
“After 20 seasons and nearly 800 career games, the time has finally come to announce my retirement,” McAnuff said via social media platform Instagram.
“It’s been a tough decision, but my body and mind have finally had enough of the rigours of day-to-day football and I definitely feel now is the right time to hang the boots up,” he added.
“I’ve put in a lot of work over the last few years to make sure I was as prepared as I could be for this day and I look forward confidently and excitedly to the next phase of my professional life.”
Despite having taken over as coach for Orient’s final 16 fixtures, while also playing in midfield, McAnuff will not be continuing on as the team’s coach. Orient finished in 11th position.
