Club career
Ulsan Hyundai
A graduate from the football club of Hyundai High School, known as an academy of K League 1 side Ulsan Hyundai, he signed his first professional contract with the club's senior team in 2018. He was originally set to reinforce their reserve team at the R League, but made an unexpected debut as a starter under manager Kim Do-hoon in the club's league opener against Jeonbuk Hyundai Motors on 1 March 2018. He played 56 minutes before being replaced by Júnior Negrão, and his side eventually suffered a 2–0 away loss. After playing his first AFC Champions League match as a 70th-minute substitute in a 2–2 away draw with Kawasaki Frontale on 18 April, he appeared as a substitute in two more K League 1 matches against Suwon Samsung Bluewings and Pohang Steelers in May.
On 24 January 2019, Oh moved on loan to K League 2 club Asan Mugunghwa, whose status was going to be changed from the police's club to a city-owned club due to a plan to abolish the auxiliary police in South Korea. On 2 March, he made his Asan debut and first professional goal in a 3–0 away win over Jeonnam Dragons. He got more opportunities at the new club, scoring seven goals in 30 K League 2 matches.
Prior to the 2020 season, Oh decided to serve his compulsory military duty, enlisting in military-owned K League 1 club Sangju Sangmu (renamed Gimcheon Sangmu the next year). After finishing his military recruit training, on 29 April, he got into the club's car, which was going to arrive at a clinic, to be tested for COVID-19, but was in a car accident. On 13 June, he made a late debut for Sangmu in a 4–2 home loss to Pohang Steelers, where he scored both of Sangmu's goals. On 22 July, he had one goal and one assist in a 2–0 home win over Daegu FC, being named the Most Valuable Player of the Round by the league's federation. Since September, he took breaks due to aftereffects of the car accident and training at the national under-23 team. He had four goals and two assists in 13 matches for about two months despite his poor physical condition.
After making four lethargic appearances in the first half of the 2021 season, Oh was discharged from Sangmu and returned to Ulsan.
Just after completing his military service at Sangmu, Oh played Group F matches of the 2021 AFC Champions League held in Thailand for Ulsan. On 26 June, he provided an assist for the team's winning goal in the first match against Viettel, where they won 1–0. On 2 July, he scored his first and second goals for Ulsan in a 3–0 win over Kaya–Iloilo, where the club set a new tournament record of 12 consecutive wins. He had three goals and two assists in six group stage matches, helping his team win all the matches. On 29 August, he scored his first goal at Ulsan Munsu Football Stadium, Ulsan's home stadium, in a 3–2 win over Incheon United. On 21 November, he scored two goals in a 3–1 home win over Jeju United, and was selected as the league's MVP of the Round for the second time. At all competitions during the second half of the 2021 season, he played 29 matches for Ulsan, and had 10 goals and four assists.
Shimizu S-Pulse
On 24 February 2022, Oh joined J1 League side Shimizu S-Pulse on a permanent deal. He scored his first goal for Shimizu in a 1–1 draw with Gamba Osaka on 10 April, his second J1 League match, but faced competition from Thiago Santana and Yūta Kamiya. He played only two matches as a starter until July, and was sidelined by sprains since August.
After Shimizu were relegated to the J2 League, Oh had two goals and five assists in 25 league appearances including six starts the next year.
Machida Zelvia
On 5 January 2024, Oh joined newly-promoted J1 League club Machida Zelvia on a season-long loan. On 30 March, he scored his first and second goals for Zelvia in a 3–1 home win over Sagan Tosu. During the 2024 J1 League, he had eight goals and two assists in 33 matches, contributing to Zelvia's third-place finish along with his compatriot Na Sang-ho.
On 5 January 2025, Oh signed a permanent deal with Zelvia. On 20 July, he was criticised for attacking opposing defender Hiroto Taniguchi with his knee irrespective of the ball in the middle of a league match against Tokyo Verdy by the press and fans. His controversial act was not followed by the referee's whistle. He scored only two goals at the league, but he led the club to their first-ever final at the Emperor's Cup by making one goal and one assist in the 2–0 semi-final win over FC Tokyo. On 22 November, he and Na Sang-ho came on as 65th-minute substitutes in the 3–1 Emperor's Cup final win over Vissel Kobe, and won his and the club's first major title.
Return to Shimizu
On 1 February 2026, Oh moved to his former club Shimizu on a five-month loan. At the J1 100 Year Vision League, he scored seven goals including a seventh-second goal against V-Varen Nagasaki during 19 appearances. His record of seven seconds was faster than a J1 League record of eight seconds, set by Hisato Satō in 2006, but was not officially recognised because it did not occur in the regular season. He received the league's Monthly MVP award for March.
On 27 June, Shimizu converted Oh's loan deal into a permanent deal.
International career
Oh started to represent South Korea at the 2015 FIFA U-17 World Cup. Under manager Choi Jin-cheul, he played four matches as a substitute until the round of 16, where South Korea lost 2–0 to Belgium, and scored the winning goal in a 1–0 win over Guinea.
By manager Chung Jung-yong, Oh was called up to the South Korea under-20 team for the 2018 Toulon Tournament and the 2018 AFC U-19 Championship. He played only two matches as a starter at the latter, where his country qualified for the 2019 FIFA U-20 World Cup as runners-up. At the U-20 World Cup, however, he became their main striker, playing all seven matches until the final including six as a starter. Before South Korea lost to Ukraine in the final, he scored each of two headers against Argentina and Japan, and scored his team's last penalty in a penalty shoot-out win over Senegal.
Oh was selected for the South Korea under-23 team for the 2020 AFC U-23 Championship by manager Kim Hak-bum. He scored a brace in their 2–1 win over Uzbekistan. After getting involved in Taeguk Warriors' first victory at the competition and qualification for the 2020 Summer Olympics, he was selected for the Team of the Tournament by Fox Sports Asia.
On 6 June 2024, Oh made his senior international debut as a 87th-minute substitute for Son Heung-min in a FIFA World Cup qualifier against Singapore, which ended in a 7–0 win. On 15 October, he scored his first international goal in a World Cup qualifier against Iraq, where South Korea won 3–2.
Style of play
Oh is a center-forward, who performs the role of target man. Noted for his physique and aerial ability, he is frequently compared with Kim Shin-wook, another South Korean international and his role model.
