Youth career

Starting his youth career with several Silesian clubs, Mrozek joined Lech Poznań's youth setup in mid-2014. In 2017, he joined English club Manchester United on a trial basis and drew interest from Crystal Palace, before making his first senior appearances for Lech's reserve team that year.

Loans to Elana, GKS & Stal

Starting from the 2018–19 season, he spent three years on loan at third division outfits Olimpia Elbląg and GKS Katowice. On 12 May 2022, Mrozek joined Ekstraklasa club Stal Mielec on an emergency loan until the end of the season, after Stal's goalkeepers Rafał Strączek and Damian Primel suffered injuries ruling them out for the remainder of the campaign. He made his Ekstraklasa debut three days later, on 15 May 2022, in a 1–1 home draw against Śląsk Wrocław which secured his team's survival from relegation. On 16 June 2022, he extended his contract with Lech until June 2024 and was sent on loan to Stal again, until the end of the season, with an option to buy. Mrozek remained a starter for Stal throughout the entire campaign, keeping 12 clean sheets in 34 league matches. After Stal made use of their buy option at the end of the season, Lech immediately exercised their buy-back clause to bring Mrozek back to the club on a new three-year deal.
