An extremely versatile player, Aaron has played in a number of positions for the Jammers but has impressed Hoops manager Ross Jenkins in the right-back position over pre-season.
The full-back has been an ever present in the team in pre-season, scoring City’s fourth goal in the 4-0 victory over Stratford Town.
Aaron joined Maldon & Tiptree in 2020 and enjoyed a fruitful four year spell with the club, helping them reach the FA Cup first round proper in 2020 where they were beaten by Morecambe.
After signing with the Hoops, Williams-Bushell said: “It feels good [to become an Oxford City player]. I'm happy to finally be here and I’m just ready to get started.
“Going up two divisions doesn’t happen too often and I just want to show people that I can play at this level.”
Manager Ross Jenkins said: “Aaron has come in and applied himself well through pre-season, he’s shown a hunger to do well and has worked very hard to earn a chance to play at a higher level.”
