Plamen Iliev is a Bulgarian professional footballer who plays as a goalkeeper for Ludogorets Razgrad and the Bulgarian national team. Iliev spent his early years with his hometown club Balkan Botevgrad, before joining Vidima-Rakovski's youth academy in 2006. He made his professional debut in 2009 at the age of 17 and quickly became a regular starter. In December 2010, Iliev moved to Levski Sofia for an undisclosed fee. Four and a half years later he signed for Romanian club Botoșani. In February 2017, he moved to Astra Giurgiu where he stayed two years before he returned to Bulgaria to join up with Ludogorets Razgrad. A former regular for Bulgaria at Under-21 level, Iliev made his senior international debut in May 2012.
In his youth years in Botevgrad, Iliev started to play football at Balkan. He joined Vidima-Rakovski when he was fourteen years old and signed his first professional contract in 2009. At the beginning of the 2009–10 season, Iliev was added to Vidima's senior squad by manager Dimitar Todorov. He made his B Group debut in the starting line-up on 8 August 2009 in a 1–1 draw against Kom-Minyor. During the season he became first choice goalkeeper and earned 23 appearances, helping his team to win promotion to the A Group. Iliev was also the first choice keeper for the team from Sevlievo in the first half of the 2010–11 season and earned praise for his performances.

On 6 April 2012, Iliev was appointed as Levski's captain, but became vice-captain for the 2012–13 season, as new coach Ilian Iliev decided to give the captain's armband to Stanislav Angelov. On 14 September 2012, Iliev signed a new contract keeping him at the club until 2016.

Ludogorets Razgrad
On 7 January 2019, Ludogorets Razgrad confirmed that Iliev had signed a preliminary contract under the Bosman ruling and is set to join the team as a free agent in June 2019 if the negotiations between Astra and Ludogorets in January didn't end with a transfer agreement, but on 12 January the teams reached an agreement and Iliev joined the team for an undisclosed fee.
