Julian played over 150 games during his three and a half seasons at Billericay, helping the club to win promotion to the National League South.

His best stop came in the 21st minute when he managed to claw away a stinging drive from Hasney Aljofree and moments later he also denied Blair Sturrock with a low block".

[12][14][15] Stevenage kept 12 clean sheets during the season, although failed to make the play-offs following a 2–0 defeat at Forest Green Rovers,[12] finishing sixth.

[12][17] At the end of the 2005–06 season, Graham Westley, the man that had brought Julian to Stevenage, left the club and was replaced by Mark Stimson.

[21] However, after Potter was sent-off in Stevenage's home game against Crawley Town, Julian made his first appearance of the season, coming on as a 63rd-minute substitute in a 3–2 defeat.

[22] Julian remained first choice goalkeeper from then onwards, making 53 appearances for the club during the 2006–07 season as Stevenage finished eighth in the Conference National.

[12] He also made a number vital saves in the club's semi-final second leg against Grays Athletic, which Stevenage went on to win by a 3–1 aggregate scoreline.

[12] This served as the catalyst for a run of eight games without conceding a goal, equalling a Conference National record when they beat Farsley Celtic 4–0 at Broadhall Way.

[12] After manager Mark Stimson left Stevenage to join Gillingham,[27] Julian refused to sign a new contract, stating he wanted to "keep his options open for the summer".

[28] Despite being on the transfer-list, Julian remained first choice goalkeeper under new manager Peter Taylor until Stevenage's 3–1 home defeat to Torquay United on 12 April 2008, his final appearance of the season.

[30] Four days later, Julian made his first league start for Gillingham, playing the whole match in a 1–0 home loss to Luton Town.

[30] It was Julian's last appearance of the 2008–09 campaign as Gillingham secured promotion back to League One after a 1–0 play-off Final win against Shrewsbury Town.

[30] Ahead of the 2009–10 campaign, manager Mark Stimson admitted he was undecided as to whether Julian or Simon Royce would start in the club's opening fixture of the season.

[33] After three straight defeats in the space of a week with Gillingham conceding seven goals,[33] Julian was replaced by Royce ahead of the club's League Cup game against Blackburn Rovers.

[42][43] After Gillingham's 7–4 away loss at Accrington Stanley,[44] Julian regained his first-team place, playing in a 2–1 home win against Stockport County on 9 October 2010.

[45] He remained as first choice goalkeeper throughout the season as Gillingham finished in eighth position in League Two,[40] narrowly missing out on a play-off place after losing three out of their last four games.

[51] As a result of Chris Day dislocating his finger,[52] Julian started in the club's first game of the 2011–12 campaign, keeping a clean sheet in Stevenage's 0–0 home draw against Exeter City.

[56][57] He subsequently missed the first three months of the season, before eventually making his first-team debut for Newport on 17 November 2012, in a 3–1 home defeat to Hyde.

[58] Julian went on to make 11 appearances during a campaign in which Newport would return to the Football League after a 25-year absence following the club's 2–0 play-off final victory over Wrexham in May 2013.

[63] On 19 October 2019, in an FA Cup fourth qualifying round match against his former club Sutton United, Julian scored an injury-time goal to earn his side a 1–1 draw and a replay.

[64][65] In September 2020, Julian joined National League South club Hampton & Richmond Borough following a successful trial period.
