In addition to her novels and short story collections, she has worked as a script advisor for Bong Joon-ho's Snowpiercer in 2013.

In 2004, her first published work of fiction, The Experience of Touch, won the inaugural Korean Science & Technology Creative Writing Award.

[5][6] Kim's short stories are often rooted in or inspired by significant flashpoints in Korean society, such as the Sewol ferry disaster, and an incident informally dubbed 'Korean Gamergate' in which a voice actress for a prominent video game posted a photo of herself wearing a shirt with the words 'Girls Do Not Need a prince', which resulted in the actress losing her job.

[8] Kim's current works that have been translated into English are I'm Waiting for You (HarperVoyager, 2021, translated by Sophie Bowman and Sung Ryu) and On the Origin of Species and Other Stories (Kaya Press, 2021).
