At age 15, after auditioning for and being rejected by most of the country labels in Nashville, Tennessee, Decker began working with Carla Wallace of Big Yellow Dog Music. One of her songs attracted the attention of Mercury Records, which offered her a recording contract. She released her debut album, Jessie James, in 2009. A few years later in 2013, she starred with her husband Eric Decker, a wide receiver in the National Football League, in the E! reality show Eric & Jessie: Game On.

On April 18, 2014, Decker released an EP through iTunes entitled Comin' Home. On Epic in 2017, she released a five-track EP, Gold, and released a surprise live EP on June 9, 2017, titled Blackbird Sessions. On October 13, 2017, she released her second full-length album and first for Epic Records, Southern Girl City Lights. On This Holiday, her first full-length Christmas album, was released on October 26, 2018.

On September 30, 2019, Decker stated, "I have a new chapter that's about to happen with my music...I have new music coming out soon. I'm working on an EP that’ll be dropping soon."

On September 18, 2020 Jessie gave ET an update after signing a new record deal with Atlantic/Warner music in January. She revealed that while she was supposed to go on tour with new music this summer, it got postponed due to the pandemic. She says "I will be putting out a Christmas single, so I will have a Christmas song out in November, but as far as my album I've been working on and recording, we actually decided today we're going to hold off. We're going to wait for the top of the year so we can do it right, 'cause I'm really excited about it."
