Spartans Born in
Edinburgh, Kader began his career at amateur team
Spartans, of the
East of Scotland Football League. On 6 January 2006, he was an 80th-minute substitute as they won 3–2 against
Scottish Third Division club
Queen's Park in the third round of the
Scottish Cup. On 5 February, he was again a late substitute in the next round as they achieved a goalless draw with
St Mirren, the team then in first place in the
First Division. In total, he spent seven years at the City Park club.
Forfar Athletic On 25 July 2012, after a successful trial, Kader joined
Forfar Athletic. He made his first appearance in the
Scottish Football League on 11 August, as the
Second Division season began with a 2–0 loss at
Queen of the South. Kader did not record a league goal until his 17th game, netting in a 3–1 home win over
Stranraer on 2 March 2013, and was also on the scoresheet in his next game two weeks later, when he scored Forfar's first of a 3–3 draw against
Stenhousemuir. Across 25 games of his first season in a nationwide league, his only other goal came on 27 April, concluding a 3–0 victory at Stranraer's
Stair Park. Forfar finished the season in a play-off place, where they lost 7–4 on aggregate to Dunfermline. Kader's second season with Forfar began in the Challenge Cup first round on 27 July 2013, with him scoring the first goal of a 2–1 win over
East Fife. It took him 18 games to achieve a goal in the newly rebranded
Scottish League One, doing so on 1 February 2014 in a 1–1 home draw with
Airdrieonians. His season ended with three goals in 30 league games. In his third season, Kader scored in two consecutive games over November 2014, helping Forfar to a 3–3 draw at
Brechin City and a 2–0 home triumph over
Ayr United. He featured in all 36 matches over the
league season, recording four goals, as Forfar made the promotion play-offs. In the semi-final first leg, he opened the scoring in a 3–0 home victory over Ayr, and in the first leg of the final, he scored the first goal of a 3–1 victory against
Alloa Athletic. However, Alloa, who were in the play-offs to maintain their place in the
Scottish Championship, came back to defeat Forfar in the second leg.
Alloa Athletic After impressing Alloa manager
Danny Lennon with his play-off performances against them for Forfar, Kader was one of five players whom he signed on 8 July 2015. He made his debut 17 days later as they won 1–0 away to
Highland Football League team
Brora Rangers in the first round of the Challenge Cup, replacing
Eddie Ferns for the last ten minutes. On 29 August, he made his league debut, as an 82nd-minute substitute for
Mark Williams in a 1–0 home loss to
Greenock Morton.
Return to Forfar Kader left Alloa by mutual consent, and returned to Forfar on 1 September 2015. The first game of his second spell came four days later, a 4–0 loss to Dunfermline Athletic at Station Park. In his next game on 12 September, he scored the first goal of his return to the team, confirming a 2–0 win at Brechin City. In a season which ended with relegation, he added only one more goal, in a 1–1 draw at Airdrieonians on 8 March 2016.
Arbroath On 10 May 2016, Kader joined up with former Forfar manager
Dick Campbell, being one of four players to sign for
Scottish League Two team
Arbroath, alongside his Forfar teammates Michael Dunlop and Gavin Malin. The team won promotion at the end of the season as League Two champions. Arbroath won the League One title in 2019, though Kader scored only once, in a 5–2 home win over Stenhousemuir on 1 December 2018. On 9 November 2019 he scored Arbroath's third goal as they wrapped up a 3–0 win against
Inverness Caledonian Thistle at
Gayfield Park. ==Personal life==
