Muller committed to the University of Texas at Austin to play college baseball for the Texas Longhorns. He was drafted by the Braves with the 44th pick of the 2016 MLB draft. He signed with the Braves, receiving a $2.5 million signing bonus, to forgo his commitment to Texas.
After signing, Muller was assigned to the GCL Braves, where he posted a 1-0 record with a 0.65 ERA in 27.2 innings pitched. In 2017, Muller pitched for the Danville Braves where he pitched to a 1-1 record and 4.15 ERA in 11 games started.

He had a 7-6 record and a 3.14 ERA in 22 starts.
Muller did not play in a game in 2020 due to the cancellation of the minor league season because of the COVID-19 pandemic. After the year, the Braves added Muller to their 40-man roster.
On June 16, 2021, Muller was promoted to the major leagues for the first time after Tucker Davidson was placed on the injured list. He made his MLB debut that day, pitching one inning and allowing two runs against the Boston Red Sox. He made his first career start on June 21 against the New York Mets, allowing 1 run over 4 innings during the 4-2 loss. On July 3, Muller was optioned back down to Triple-A Gwinnett. In 2021 with the Braves he was 2-4 with a 4.17 ERA in nine games (8 starts). The Braves finished with an 88-73 record, clinching the NL East, and eventually won the 2021 World Series, giving the Braves their first title since 1995.
