Mills attended Lake Forest High School in Lake Forest, Illinois where he also competed in the shot put and discus. He committed to the University of Notre Dame to play college football and enrolled early beginning in the spring semester of 2020.
During Notre Dame's 27-17 win over Indiana during the first round of the 2024 College Football Playoff, Mills suffered a torn ACL while sacking Indiana quarterback Kurtis Rourke. Although Notre Dame head coach Marcus Freeman initially said there was "optimism" Mills could have returned for the team's next match against Georgia, he was ruled out of the rest of the season on December 23.
As a true freshman at Notre Dame in 2020, Mills played in 9 games and made his first start in the 2021 Rose Bowl against Alabama. He played in all 13 games in 2022 and recorded 24 total tackles throughout the season.
Mills was selected by the Seattle Seahawks with the 142nd pick in the fifth round of the 2025 NFL draft. On July 15, Mills was among six Seahawks rookies placed on the non-football injury list following his ACL tear at Notre Dame. He was activated from the list on December 13. He made his NFL debut the next day, playing seven snaps in Seattle's 18-16 win over the Indianapolis Colts. He recorded his first career sack during the second quarter of Super Bowl LX on February 8, 2026, when he pushed New England Patriots guard Jared Wilson into quarterback Drake Maye.
