In 2009, Kubler became just the second player in history (after Rafael Nadal) to go undefeated through the World Youth Cup and Junior Davis Cup. Following his success at the Junior Davis Cup, Kubler won five titles in a row which saw his junior ranking rise to No. 3 in the world.

Kubler won six junior titles throughout his career and achieved the combined No.1 world ranking in May 2010 with a win–loss record of 67–17 in singles and 40–19 in doubles.

Kubler made his professional debut in September 2008 at the Australia F7 Futures event on the ITF Men's Circuit, the third tier for men's professional tennis. Kubler won through qualifying to make his main draw professional debut but lost in the first round to compatriot Marinko Matosevic.{{Cite web |url=https://www.itftennis.com/en/tournament/australia-f7-futures/aus/2008/m-fu-aus-07a-2008/draws-and-results/ |title=Australia F7 Futures 2008 Tennis Tournament | ITF |access-date=29 June 2022 |archive-date=29 June 2022 |archive-url=https://web.archive.org/web/20220629033150/https://www.itftennis.com/en/tournament/australia-f7-futures/aus/2008/m-fu-aus-07a-2008/draws-and-results/ |url-status=dead }}

In 2010, following continued success on the junior circuit, Kubler was granted wildcards into the Brisbane International and Sydney International qualifying draws, but failed to win a match at either event. He was then awarded a wildcard to make his ATP Tour and Grand Slam debut at the 2010 Australian Open. Drawn against 24th seed Ivan Ljubičić, Kubler was handily beaten 6–2 6–1 6–1 in a lacklustre display.

In April, Kubler won the first main draw professional match of his career at the Australia F3 Futures event in Ipswich, where he went on to make the final, losing to Brydan Klein.{{Cite web |url=https://www.itftennis.com/en/tournament/australia-f3-futures/aus/2010/m-fu-aus-03a-2010/draws-and-results/ |title=Australia F3 Futures 2010 Tennis Tournament | ITF |access-date=29 June 2022 |archive-date=29 June 2022 |archive-url=https://web.archive.org/web/20220629033718/https://www.itftennis.com/en/tournament/australia-f3-futures/aus/2010/m-fu-aus-03a-2010/draws-and-results/ |url-status=dead }} Kubler's best results for the remainder of 2010 were a string of semi-final appearances at Netherlands F2, Italy F23, Portugal F5 and Spain F37 Futures events.

Kubler missed the start of the 2011 Australian summer of tennis due to a knee injury.{{Cite web |title=Kubler out of action with knee trouble |url=https://www.tennis.com.au/news/2010/12/30/kubler-out-of-action-with-knee-trouble |access-date=2022-06-29 |website=Tennis.com.au}} Further injuries during the year limited his play before he won the first professional title of his career at the USA F28 Futures event in Birmingham, defeating Yoshihito Nishioka in the final.{{Cite web |title=Kubler wins first Futures title |url=https://www.tennis.com.au/qld/news/2011/11/01/kubler-wins-first-futures-title |access-date=2022-06-29 |website=Tennis Queensland }} Kubler won his second professional title the next week at the USA F29 Futures event in Niceville, salvaging an otherwise frustrating year with injury. He finished the 2011 season ranked No. 530 in the world.

Kubler began the 2012 season by entering four Futures tournaments in Florida after again bypassing the Australian summer. Kubler lost in the final of USA F1 to Jack Sock and USA F3 to Brian Baker before winning the USA F4 event in Palm Coast to cap off a promising start to the year. Kubler returned to Australia in March, where he lost the final of the Australia F3 event against Sam Groth but defeated John Millman to claim the Australia F4 title in Bundaberg. Kubler then travelled to Europe, to compete in further Futures tournaments and the first Challenger events of his career, where he made a quarter-final at the Todi Challenger in September. Following more success on the Futures tour, Kubler's world ranking steadily rose, peaking at a career-high No. 268 on 29 October 2012. He ended the 2012 season ranked No. 332 in the world.

In 2013, Kubler played in Futures tournaments throughout the United States, Spain, Great Britain, Australia, Italy and Egypt, but only on clay due to ongoing knee concerns. He won three Futures tournaments for the year, however his ranking dipped to No. 397 to end the season.

Kubler again chose to miss the Australian summer of tennis, opting to play Futures events in Egypt and Spain. He entered six tournaments during this stretch, making the final of three and winning one. In March, Kubler qualified for the main draw of Challenger events in Panama and Barranquilla, but failed to win a match at either tournament. In April, he competed in further Challenger events in Savannah and Tallahassee, making the second round at both tournaments. In May, Kubler qualified for the ATP event in Düsseldorf, his first ATP World Tour event since the 2010 Australian Open.

File:Jason Kubler 6, 2015 Wimbledon Qualifying - Diliff.jpg]]Kubler skipped the Australian summer of tennis for a fifth consecutive year. He instead played a variety of Challenger events across South and North America, his best result being a quarter-final appearance in Sarasota. In May, Kubler attempted to qualify for the French Open, but lost in the first round to Tim Pütz. This was Kubler's first appearance at a Grand Slam event in five years, albeit in the qualifying tournament. In June, Kubler entered the qualifying tournament at Wimbledon, marking his first competitive appearance on the grass in three years.{{cite web|url=http://www.theroar.com.au/2015/06/23/wimbledon-qualifying-australian-perspective/|title= Wimbledon qualifying: Australian perspective|publisher=theroar.com.au|author= Shane Jones|date=23 June 2015|access-date= 23 June 2015}} He defeated Rui Machado in straight sets in round 1 but was eliminated in the second round by Aleksandr Nedovyesov, who went on to qualify for the main draw. In September, Kubler attempted to qualify for the US Open, but lost in the opening round to Facundo Bagnis. This was Kubler's first competitive hard court appearance at any professional level in five years. Following the US Open, Kubler underwent knee surgery. A lacklustre year on the court and limited tournament play saw Kubler's ranking freefall to No. 544 to end the 2015 season.

After rehabbing from knee surgery, Kubler commenced the 2016 season by playing several Futures events in North America. He reached the quarter-final of USA F6 and semi-final of USA F8 in February. At USA F9 in March, Kubler retired in the first round. In May, just eight months after his last surgery, Kubler underwent the sixth knee operation of his career which side lined him for the rest of 2016.{{cite web|url=http://www.tennis.com.au/news/2017/03/21/kubler-returns-in-canberra|title=KUBLER RETURNS IN CANBERRA|date=21 March 2017|website=Tennis.com.au|access-date=21 March 2017}} As a result, Kubler finished the year ranked outside the world's top 1000.

After a year out of the game and without a world ranking, Kubler returned to professional tennis in March at the Australia F2 and F3 Futures events in Canberra. In the lead up to the events, Kubler was frank about his future in the sport, commenting that another knee operation would likely mark the end of his career.{{Cite web |last=Tiernan |first=Eamonn |date=2017-03-23 |title=Comeback kid Kubler back on the winner's list at ACT International |url=http://www.smh.com.au/sport/act-sport/act-claycourt-international-marks-comeback-for-jason-kubler-20170322-gv40vs |access-date=2022-06-29 |website=Newcastle Herald }} After little success in Canberra, Kubler travelled to Europe in April for Futures events in Spain and Italy. Although Kubler managed to make a semi-final appearance at Spain F12, the highlight of his European trip was a doubles title with compatriot Alex Bolt at the Italy F14 tournament. This was Kubler's first professional trophy of any kind since 2014.

In October, Kubler won through qualifying at the Traralgon ATP Challenger and made a remarkable run to the final after defeating two former top 100 players in Taro Daniel and Matthew Ebden. He defeated Alex Bolt in the final to claim his first Challenger title since 2014, which skyrocketed his ranking inside the world's top 350. Kubler was expected to compete in the Australian Wildcard Playoff in December for a spot in the 2018 Australian Open, but ultimately withdrew alongside a host of top-seeded players.{{Cite news|url=http://www.tennisworldusa.org/tennis/news/ATP_Tennis/49807/2018-ao-wildcard-playoff-alex-bolt-and-alex-de-minaur-lead-the-field/|title=2018 AO Wildcard Playoff: Alex Bolt and Alex De Minaur lead the field|work=Tennis World USA|access-date=2017-12-23}} Kubler finished the year ranked No. 341 in the world.

Kubler started his 2018 campaign at the Playford Challenger in South Australia, which he won after qualifying. The victory saw Kubler move inside the world's top 250 for the first time since 2015. Following an impressive run of form and a huge improvement in ranking over the past six months, Kubler was awarded the final wildcard into the 2018 Australian Open, his first Grand Slam appearance in eight years.{{cite web|url=http://www.heraldsun.com.au/sport/tennis/alexei-popyrin-and-jason-kubler-secure-australian-open-wildcards/news-story/90efefb55997dff920f27c16764ae8f8|title= Alexei Popyrin and Jason Kubler secure Australian Open wildcards|publisher=Herald Sun|date=6 January 2018|access-date=7 January 2018}} Kubler faced 10th seed Pablo Carreño Busta in the first round, where he lost in a highly competitive four-set match. Kubler showed plenty of promise in the match, leading by a break in both the first and third sets, but failed to capitalise on his opportunities. Following the Australian Open, Kubler competed in nine Challenger events across Australia and Asia from February to May. His best results through this stretch included three semi-final appearances at the Burnie International, Quijing International and Seoul Open. Kubler improved his world ranking to No. 160 following the Asian swing, his best world ranking in three years.

At the French Open, Kubler lost in the first round of qualifying to Gonçalo Oliveira. Following the French Open, Kubler proceeded to lose in the first round at his next three Challenger tournaments before making a semi-final run at the Ilkey Trophy, where he eventually lost to Oscar Otte. The result saw Kubler return to the world's top 150 for the first time in more than three years.

Kubler then entered the Wimbledon qualifying tournament and showed good form through his first two matches, defeating Arthur De Greef and Adam Pavlásek. In the final round of qualifying, Kubler defeated Canadian journeyman Peter Polansky in four-sets to qualify for the Wimbledon main-draw for the first time in his career.

Following Wimbledon, Kubler entered the Winnipeg Challenger. As the fourth seed, Kubler dropped just one-set the whole tournament to claim his second Challenger title of the year, defeating Lucas Miedler in the final. The result saw Kubler move to No. 114 in the ATP rankings, eclipsing the career high he set way back in November 2014. To finish his Canadian tour, Kubler made the semi-final of the Gatineau Challenger before withdrawing from the Granby Challenger with knee soreness.

Kubler then attempted to qualify for the Washington Open, an ATP 500 event.

After being sidelined for 10 months due to ongoing knee issues, Kubler made his return to competition on the ITF World Tennis Tour in November. He played two events in Brisbane and Carrara, making the final in the latter.

Kubler attempted to qualify for the 2025 Australian Open but fell in the opening round to Thiago Monteiro, causing his ranking to tumble outside the Top 800. With limited opportunities at higher-level events, he turned to the ITF World Tennis Tour, where he found immediate success. In February and March, he claimed back-to-back titles in Burnie and Launceston, the latter capped by a win over Cruz Hewitt, son of Australian tennis legend Lleyton Hewitt in the final. Kubler’s resurgence continued in April with his ninth career Challenger title in Gwanju, followed by another ITF title in Baotou. His impressive run of form sparked a remarkable rise in the rankings, surging more than 600 places to reach No. 210 in just four months.

In May, Kubler attempted to qualify for the French Open but was defeated in the second round of qualifying by James Trotter.
