Born in Næstved, Makienok began his professional career at Herfølge Boldklub, which later became HB Køge, making his debut in 2009, before joining Brøndby IF in January 2012 for a fee of €550,000. After a two-and-a-half-year spell at Brøndby, where the club barely avoided relegation, he was signed by Italian club Palermo for a fee reported to be €2.3 million in August 2014. Palermo then loaned him out to English sides Charlton Athletic and Preston North End, before he signed with Dutch side FC Utrecht in 2017. After two European appearances for the club, he suffered a knee injury which kept him sidelined for two years. He then played for Dynamo Dresden and FC St. Pauli in Germany before returning to Denmark in 2022 where he joined AC Horsens.
Makienok has also represented Denmark at senior and several youth levels, gaining his first cap for the senior side on 22 March 2013 as a 85th-minute substitute in a 2014 FIFA World Cup qualifier against Czech Republic which ended in a 3–0 win for Denmark.[2]
Career
Early career
Makienok grew up in Herlufmagle, and started playing for local club Suså IF at the age of 4, before making the move to Næstved Boldklub a few years later.[1][3] On 27 August 2007, he transferred to the Herfølge Boldklub youth academy.[4] He later told in the radio-show Fodboldeffekten on Radio 100, that Næstved Boldklub tried to retain him by offering him a job in a local Shell fuel station, due to lacking funds to pay players.[5][6] After having spent a year in Herfølge, Makienok signed a five-year contract with the club.[7] On 22 June 2009, he was effectively promoted to the first team competing in the Danish 1st Division (second highest division).[8] He made 22 goals in 58 league appearances for Herfølge and since HB Køge, as part of a 2009 merger.[9]

Makienok joined Brøndby IF on 28 January 2012 on a €550,000 transfer from HB Køge, signing a four-year contract which tied him to the club until the summer of 2016. He made his debut on 4 March 2012, in a 1–0 win against SønderjyskE.[10] He scored his first goal for the club on 18 March 2012 in a 2–1 away win over FC Nordsjælland.[11] He scored a total of 11 goals in 33 league and cup appearances in the 2011–12 season for HB Køge and Brøndby.
In the following season, Makienok was rewarded with Player of the Month of the Danish Superliga for his performances during November 2012.[12] In the 2012–13 season he amassed 15 goals in 34 league and cup appearances, as Brøndby barely avoided relegation from the Superliga in the last fixture of the season against Horsens.
On 20 August 2013, Brøndby announced that they had accepted an €3.8 million (DKK28.5 million) offer from a Russian club for Makienok.[13] However, Makienok was not interested in the move and decided t stay.[13] According to multiple Danish newspapers, he turned down a weekly salary of €34,000 (€1,632,000/year)[14] from Russian club FC Terek Grozny.[15] In the same year, he caught the attention of several French clubs[16] and English sides Crystal Palace[17] and Fulham while his price tag was reported as over €4 million.[18] According to several Danish media sources, Makienok had rejected a contract extension wanting to pursue new challenges during the 2014 summer transfer window.[19]
On 31 July 2014, Makienok made his Europa League-debut starting in a 3–0 away defeat to Belgian side Club Brugge.[20] During the last weeks of the 2014 summer transfer window, new rumours circulated about foreign interest in him. Several Serie A clubs revealed their interest, with Palermo leading Atalanta, Cesena and Scottish side Celtic in the chase, as his price tag was now €3 million according to Danish media.[21]

On 15 October he came off the bench in the 79th minute to score his first league goal of the season, with a dramatic injury time equaliser as he latched on to Gallagher's pin point cross to head home, which stretched Preston's unbeaten run to five games after a slow start to the season.[29]
Utrecht
On 7 June 2017, Makienok signed a three-year contract with Dutch Eredivisie club FC Utrecht, where he was meant to succeed Sébastien Haller as the team's target-man.[30][31] After making two appearances in the Europa League qualifiers he tore his anterior cruciate ligament keeping him sidelined for a lengthy period.[32][33] Makienok had multiple complications and setbacks during his rehabilitation, only making his comeback on the pitch two years after suffering the injury, on 31 October 2019 in a 4–1 cup win over fifth tier club Excelsior '31, in which he scored a goal.[34][35] A few days later, on 3 November, he was subbed on against Fortuna Sittard in the Eredivisie and scored his first goal in the Dutch league only three minutes later as Utrecht won 6–0.[36] After the match, he said that the comeback felt "surreal" and "a dream come true".[37] In an interview with Simon Routledge in the radio-show Fodboldeffekten on Radio 100, Makienok stated that he had "almost felt depressed" during his two years away from football.[38][5]
Dynamo Dresden
On 29 January 2020, Dynamo Dresden announced Makienok's signing on a six-month deal.[39] He was sent off with a red card seven minutes into his debut on 7 February against Darmstadt 98 after coming on as a substitute in the 70th minute of the match after stepping illegally on opposing goalkeeper Marcel Schuhen.[40][41] Makienok made his first goal for the club on 28 February, scoring the winner on a return ball in a 2–1 win over Jahn Regensburg.[42]

FC St. Pauli
On 29 August 2020, Makienok signed a two-year contract with FC St. Pauli where he was expected to replace Henk Veerman.[47] After signing, Makienok stated that he had always perceived St. Pauli as "a special club", whose values of "equality, tolerance and respect" he shared.[47] The same day as the move was announced, Danish tabloid B.T. revealed that Makienok had turned down an offer from Danish Superliga club OB.[48]
Horsens
On deadline day, 31 August 2022, Makienok joined Danish Superliga side AC Horsens on a deal until June 2023.[49] During the spring season, Makienok broke both an arm and a leg. For this reason, his stay in Horsens was never really good, which is why he left the club after the 2022-23 season.[50]
In August 2013, Simon Makienok started dating the Danish TV-host Ibi Støving who is 16 years older than him. Ibi has a son, Anakin, with the former professional footballer Tobias Grahn.[52] The couple revealed on their personal blog crystalkidbabyshark.com that Makienok had proposed to Ibi on 4 April 2014. They got married on 6 September 2014 in Holmen Church in Copenhagen.[53]
On 3 December 2019, it was confirmed that Makienok and Støving had split a year prior to the report, as rumours had emerged after the two had unfollowed each other on Instagram.[54] It was later revealed that Makienok had started dating Støving's friend, The Voice radio-host Ida-Sophia Petersen.[55]
