The family moved to Los Angeles when Sierra was young to chase entertainment careers. She grew up singing in church alongside her older sister Lauryn and younger sister Tiffanie.

Her first on-screen role came at age 13 in Tyler Perry's 2007 film Daddy's Little Girls, where she played a character named Sierra. Lauryn and Tiffanie also appeared in the film.

McClain's big break came in 2016 when she was cast as Nessa Parker on Fox's Empire. The role, which ran for two seasons, put her in front of millions of weekly viewers and opened doors to bigger parts. In 2018 she starred as Tosha in the dance film Honey: Rise Up and Dance. The following year she joined the cast of Netflix's Mindhunter, playing Tanya Clifton in the show's second season.

From 2020 to 2023 she played Grace Ryder, a firefighter-paramedic, on Fox's 9-1-1: Lone Star. The role made her a series regular for three seasons and became her most visible acting credit. Meanwhile, her music career progressed in parallel. The McClain sisters, originally called 3McClainGirls, released their debut single Santa Baby in 2013.
