Jayden arrived at Priestfield in January 2023, shortly after the takeover of the club involving Brad and Shannon Galinson.
The 23-year-old winger played in the Tottenham Hotspur academy but, on leaving the club, impressed at non-league level with Bedfont Sports and Hendon before a fruitful 2022-23 campaign with Dulwich Hamlet where he netted four times in 22 appearances.
He made his Gillingham debut in April 2023 during an away game against Bradford at Valley Parade before starting two weeks later at Salford in a 1-0 win.
