In 2015, Jackson started the season with Round Rock. He converted to the bullpen in May after having started 97 of his first 101 professional games. He was called up to the majors for the first time on August 6, 2015. However, he was sent back down to Round Rock on August 11, before making an appearance with the Rangers.

The Rangers again promoted Jackson to the major leagues on September 1. In 2015 with Texas he was 0-0 with a 10.80 ERA in 11.2 innings, and his fastball velocity of 96.8 mph was in the top 5% in baseball.

Atlanta Braves (2017–2021)
On December 8, 2016, the Rangers traded Jackson to the Atlanta Braves in exchange for pitchers Tyrell Jenkins and Brady Feigl.
In 2017 in the majors he was 2-0 with a 4.62 ERA in 50.2 innings over 43 relief appearances, and the hard-hit percentage against him was 41.5%, in the worst 2% in baseball. Jackson was designated for assignment on December 20, 2017.
Jackson had his contract purchased by Atlanta on April 4, 2018. He was later designated for assignment on April 15, 2018. He cleared waivers and was outrighted to the Gwinnett Stripers. He had his contract purchased again on May 6, and was again removed from the roster two days later. On June 5, he was called up once again. Jackson was later designated for assignment again on June 13. He was called up once again on June 17. With AAA Gwinnett in 2018 he was 2-1 with a 1.69 ERA, in 21.1 innings in which he struck out 34 batters (14.3 strikeouts per 9 innings), in 10 games (one start). With Atlanta, he was 1-2 with a 4.43 ERA and one save and three holds in 40.2 innings in which he struck out 46 batters (10.18 strikeouts per 9 innings). In 2018 he stopped throwing a changeup, threw a lower percentage of four-seam fastballs and curveballs, and began to throw his slider more.
In 2019, he was 9–2 with 18 saves and nine holds, and a 3.84 ERA with 106 strikeouts (13.1 strikeouts per 9 innings) in innings over 70 relief appearances. Jackson induced a 60.5% ground ball percentage, the third-highest in baseball (minimum 70 innings). He induced a chase rate of 35.1%, in the best 4% in baseball, and a whiff percentage of 36.7%, in the best 3% of baseball.
In 2020, he was 2–0 with a 6.84 ERA in innings over 19 relief appearances. He had a barrel percentage against of 3.1, in the best 5% in baseball.
In 2021, Jackson was 2–2 with a 1.98 ERA and 70 strikeouts in innings in 71 games (sixth-most in the NL). His 31 holds ranked second in the major leagues. Between 2015 and 2021, he relied mostly on his 88 mph ground ball-inducing slider and 96 mph four-seam fastball, also throwing an 85 mph curveball. He won a championship ring that year as the Braves won the World Series in six games.
Prior to the 2022 season, the Braves disclosed that magnetic resonance imaging had revealed damage to the ulnar collateral ligament of Jackson's right elbow. He underwent successful Tommy John surgery on that elbow on April 13, 2022. In May, Jackson was granted a $3.6 million salary for the 2022 season via arbitration. He missed the entire 2022 season due to his surgery.
San Francisco Giants
On January 9, 2023, the San Francisco Giants announced that Jackson had been signed to a two-year contract, for a guaranteed $11.5 million, with a club option for a third season. He will earn $3 million in 2023, and $6.5 million in 2024. The Giants have an option for $7 million for 2025, with a $2 million buyout if the team declines to exercise it.
