In August 2025, Tjen qualified for her first Grand Slam main draw with a straight sets win over third qualifying seed Aoi Ito at the 2025 US Open. She became the first Indonesian player in a major since Angelique Widjaja at the 2004 US Open. In the first round, she defeated 24th seed Veronika Kudermetova in three sets, becoming the first Indonesian woman to win a Grand Slam match since Widjaja at the 2003 Wimbledon Championships. Tjen lost in the second round to Emma Raducanu in straight sets.
During her WTA 250 debut at the São Paulo Open in September 2025, Tjen became the first Indonesian woman to reach a WTA quarterfinal since Angelique Widjaja at the 2004 Wismilak International. After defeating third-seed Alexandra Eala in the quarterfinals and sixth-seed Francesca Jones in the semifinals, Tjen became the first Indonesian player to reach a WTA final since Widjaja in 2002. She lost the final to Tiantsoa Rakotomanga Rajaonah.
