2010–2012: Early career and debut with Bargh Shiraz

Esteghlal
As summer 2012, Hosseini joined Esteghlal signing a three-year contract. Later in an interview with Navad, he revealed that he declined a huge offer from Persepolis to join the team he supported during his childhood. This claim was later confirmed by Mohammad Rouyanian who was Persepolis' chairman at the time. On 9 July 2013, he made his debut in a friendly against Dynamo Kyiv in which he conceded a goal as Esteghlal beat their opponent 2–1. His first competitive appearance for Esteghlal was in Hazfi Cup against Caspian Qazvin on 10 December 2013.
After finishing his mandatory service, Hosseini returned to Esteghlal as backup for Mehdi Rahmati. After Rahmati was sidelined for Esteghlal's opening match of the Persian Gulf Pro League season against Naft Tehran due to injury, Hosseini started the match and made his season debut. He finished the season with 8 matches.
2017–18: Record Iranian top division league unbeaten streak
At the beginning of the season Mehdi Rahmati was the first choice keeper, however after failing to win four games out of the first five matches of the season, manager Alireza Mansourian decided to start Hosseini ahead of Rahmati. Hosseini made his season debut in the league on 15 September against Pars Jonoubi Jam in which he conceded 2 goals. He wore the captain's armband for the first time in the next game, on 20 September, in a league match against Zob Ahan. He kept his first clean sheet of the season in a 0–0 draw against Foolad. After keeping a clean sheet on 5 January 2018, he surpassed Alireza Beiranvand's record of 721 minutes without conceding a league goal in Persian GulfPro League in a 0–0 draw against Tractor Sazi. On 12 January, he surpassed the record for consecutive minutes in Iranian top division league set by Bahram Mavaddat in 1976 by 28 minutes against Saipa; he set the new all-time record at 872 consecutive minutes without conceding a goal. Reza Asadi finally ended his goalless streak by beating him in the 85th minute of the same match. His record is broken by Payam Niazmand in October of 2019. His performance earned him Navad's player of the month award at the end of January. On 24 February, Hosseini picked up a yellow card for time wasting in a match against Foolad, which ruled him out of the Tehran derby the following week.
International career
Hosseini represented Iran U17 at the 2009 FIFA U-17 World Cup in Nigeria. He also represented Iran U20. He was called to join Iran' training camp by Carlos Queiroz on 3 November 2017. However he did not make into the final squad. On 17 March 2018, he made his official debut as a substitute for Hamed Lak at the half-time against Sierra Leone, which Iran won 4–0 and Hosseini kept a cleen-sheet.
