Kim Eun-jae, known professionally as Ejae, is a South Korean and American singer, songwriter, and record producer.
A graduate of New York University Tisch School of the Arts, Kim started as a trainee for SM Entertainment in 2003 but did not debut as a soloist or music group member. She moved into songwriting and producing and initially became known for her work with K-pop acts Red Velvet, Aespa, Twice, Le Sserafim, and other South Korean artists. She co-wrote the topline for "Psycho" for girl group Red Velvet, which topped the US Billboard World Digital Songs chart.
Kim had her international breakthrough in 2025, providing the singing voice for Rumi in the Sony Pictures Animation and Netflix film KPop Demon Hunters (2025) and co-writing several songs on its soundtrack. "Golden", one of the songs she co-performed and co-wrote for the film, topped the Billboard Hot 100 and other global music charts, and earned four Grammy Award nominations (including Song of the Year).
It became the first K-pop song to win numerous North American industry awards, including the Grammy Award for Best Song Written for Visual Media, the Golden Globe Award for Best Original Song, and the Academy Award for Best Original Song. Kim released her debut solo single "In Another World" on October 24, 2025.
