Rangers
After spending years at the Rangers academy, Telfer signed his first professional contract in November 2011.
He would make one competitive first team appearance for the club against Stenhousemuir in April 2014. Telfer later describe playing in the Scottish Youth Cup Final as his biggest game of his life.
At the end of the 2013-2014 season, Telfer"s future at Rangers appeared to be in doubt when Dundee United were reported to be keen to sign him. Dundee United then made a £50,000 bid to sign Telfer, which was rejected by Rangers, who offered him a new contract.
Dundee United
After rejecting the offer of a new contract, Telfer signed for Dundee United in June 2014, with a compensation payment to be agreed between the clubs.
However, there was the possibility that Dundee United could avoid a tribunal. Telfer"s departure from Rangers was commented on by manager Ally McCoist, who described him as a "great prospect" and said that the club had wanted to keep him but it had been his decision to leave. To the conclusion, the panel was reached and ordered Dundee United to pay Rangers compensation, which was paid around £200K by January.
He made his Dundee United debut as a substitute against Aberdeen in the opening match of the 2014-2015 season.
On 4 December 2014, Telfer was named as SPFL Young Player of the Month for November 2014. Telfer started 2015 off by scoring United"s sixth goal in a 6–2 Derby victory over local rivals Dundee.
This was followed up by a brace against Motherwell later that month, in his fourth start for the terrors. Telfer was included as an un-used substitute for the Scottish League Cup Final, as Dundee United lost 2–0 to Celtic.
Despite this, Telfer made 25 appearance and scoring four times in first season at the club
= Livingston With his chances at Tannadice limited, Telfer moved on loan to Scottish Championship side Livingston in January 2016, in a deal until the end of the season. Telfer has represented the Scotland U17 and Scotland U19 sides.
