See you on the court!

Ognjen started playing basketball at seven years old as a pupil of Jovan Popovic Grammar School in Krusevac, in OKK Junior club, where he was coached by physical education teacher Bosko Vranes. In 2006 he moved to Belgrade with his family where, at not even 11 years old, he joined the youngest categories of Partizan and spent the next 6 years there.

Joining Mega Vizura in the 2012/13 season marked the beginning of his professional career. This was followed by a loan to Smederevo 1953 club during the first half of Basketball League of Serbia 2013/14, where he had a prominent role as the best shooter in that phase of the competition. Nearing the beginning of Serbian Super League in 2014, he returned to Mega Vizura. He spent the next four years playing for this club, where he participated in the greatest successes in the history of Mega when they won the Radivoj Korac Cup in 2016 and entered the finals of ABA league that same year. Also, in the season 2016/17 Mega played the FIBA Champions League, which was Ognjen’s debut in this competition.

In the summer of 2017 he was selected with the 58th overall pick by the New York Knicks club for which he played in the summer league. However, grave health problems began. New York sent him to the hospital where he was diagnosed with pulmonary embolism and taken out of the game for the following six months. Considering the circumstances, he decided to renew the contract with Mega and secure his return to the court in the same club where he played for previous several seasons.

In June 2018, he signed a two and a half year contract with then first league club San Pablo Burgos, only to return to Partizan on February 12th 2019, where he debuted in the EuroCup. He won an ABA league Supercup with Partizan (2019) and two Radivoj Korac Cups (2019 and 2020). Also in 2020, he wins the MVP award of Radivoje Korac Cup. After his contract expired, end of 2020/2021 season, Jaramaz leaves Partizan to sign a three-year contract with Bayern Munich. He wins the German Cup with this club in 2022/23 season. In July 2023, he returned to Partizan. Po isteku ugovora, na kraju sezone 2020/21, Jaramaz je napustio Partizan i potpisao trogodišnji ugovor sa Bajern Minhenom. Sa Bajernom je osvojio Kup Nemačke u sezoni 2022/23. In July 2023, he returned to Partizan.
