The left full-back/midfielder had been at the club since he was a small lad and grew up to be the captain of Liverpool's Under-18 side. He made the step up to Jürgen Klopp's first team at Melwood and was part of the squad that travelled to the US in the summer of 2019. He played the full ninety minutes of the FA Cup fourth round replay against Shrewsbury on 4 February 2020 and was loaned to French Ligue 2 side Amiens for the 2020/21 season. However, after just nine appearances, the loan was cut short in January 2021 and Lewis joined Plymouth Argyle for the remainder of the season.

Lewis scored once in twenty League One appearances with Plymouth and was loaned to Livingston for 2021/22. He impressed early in the season before suffering from a fractured metatarsal. However he recovered by the end of the season and featured in five of the final eight games. On 22 June 2022 it was announced that he would be spending the 2022/23 on loan at Newport County. He impressed making 28 appearances at left back but his season was brought to an early end with a hamstring sustained in February and he returned to Liverpool for recuperation. Lewis impressed enough however for another season long loan spell at Newport to be agreed for 2023/24. Lewis' contract at Liverpool expired in June 2024 and he signed a one year deal with Morecambe. Although The Shrimpers were relegated to the National League, he scored once and provided six assists in 44 appearances, earning him a contract with League Two Chesterfield for 2025/26.
