Born and raised in the small town of Simpele, Rautjärvi located near the Russian border, Joronen joined Fulham Academy in 2009.[3] In June 2010, Joronen signed his first professional contract with the club, which would keep him there until 2013.[4]
In May 2012, Joronen signed a two-year extension with Fulham that would keep him with the club until 2014.[5] Five months later, on 25 October 2012, Joronen joined Maidenhead United on loan[6] and in February 2013, Joronen was loaned to Cambridge United.[7] Only a day later, Joronen returned to Fulham after he refused to be named as a substitute for Cambridge.[8]
After a loan spell at Maidenhead United, Joronen then moved back to Finland, where he joined Veikkausliiga side FC Lahti on loan until August.[9] After making eighteen appearances for the club, where he established himself as a first-choice goalkeeper, Joronen returned to his parent club in early August.[10]

Joronen joined Accrington Stanley on loan for one month on 17 October 2014.[14] He made his Accrington Stanley debut the next day, starting in goal, in a 2–1 loss against Stevenage.[15] However, after making three more appearances at Accrington Stanley whilst on loan, he returned early after dislocating his kneecap during a League Two match against Morecambe.[16] Then, it was announced that Joronen would be out for three to four months.[17]
On 27 August 2015, Joronen signed for Stevenage on loan until January 2016.[18] He made his Stevenage debut two days later, in a 1–1 draw against Dagenham & Redbridge.[19] Joronen scored with a long-range clearance in a match against Wycombe Wanderers on 17 October 2015.[20] He then kept his first clean sheet in a 3–0 win over Gillingham in the first round of the FA Cup.[21] However, after making eleven appearances for the side, Joronen suffered an injury during the match against Gillingham and subsequently returned to his parent club.[22] After returning to his parent club, Joronen signed a contract extension, keeping him there until 2017.[23]
In the 2016–17 season, Joronen was featured three times in the EFL Cup, being the first-choice goalkeeper ahead of Bettinelli.[24][25] At the end of the 2016–17 season, he was offered a new contract by the club.[26]
AC Horsens
However, instead of signing a new contract, Joronen left Fulham to join Danish side AC Horsens, signing a two-year contract on 10 July 2017.[27]
Joronen made his AC Horsens debut in the opening game of the season, in a 2–1 win over AGF Aarhus.[28] On 4 August 2017, he kept his first clean sheet for the side, in a 1–0 win over Silkeborg, a win that saw the club go to the top of the table.[29]
