Birmingham City

After leaving school Boyd-Munce came to England where he took up a two-year scholarship with Birmingham City F.C.'s Academy in July 2016.^[5] Academy coach Steve Spooner described him as a "good technician [who] has a very good engine and displays the capabilities of a real box to box midfield player."^[5] He established himself in Birmingham's under-18 team, played for the under-23s,^[2] and was a member of the youth team that reached the semifinal of the 2017–18 FA Youth Cup, in which Chelsea beat Birmingham 7–0 on aggregate.^[6] He was not offered professional terms after his two years, instead accepting a third scholarship year.^[7]

In August 2018, Boyd-Munce spent a month on loan to Redditch United. He played four matches in the Southern League Premier Division South and, according to senior development coach Richard Beale, found it an eye-opening experience.^[8][9] Boyd-Munce went on to become a regular for Birmingham's development squad team the 2018–19 season, making 21 appearances as they finished as runners-up in the Professional Development League northern section and lost out to Leeds United on penalties for the overall title.^[10][11] He was offered a two-year deal in March 2019,^[8] and signed it in June.^[10]

Boyd-Munce made his competitive debut for Birmingham on 6 August 2019 in the EFL Cup first round. Manager Pep Clotet fielded an inexperienced team for the visit to Portsmouth, and Boyd-Munce came into the 3–0 defeat as a second-half substitute, replacing Jude Bellingham after 81 minutes.^[12] He made his first appearance in the Championship on 7 February 2020, as a very late substitute in a 3–1 win away to Bristol City, and made a further five, all from the bench, in the last few matches of the 2019–20 season.^[13] In November 2020, new head coach Aitor Karanka gave Boyd-Munce a difficult first league start, playing out of position at left wing-back directly marking AFC Bournemouth's in-form winger David Brooks.^[14] Later that month, he injured an ankle and did not return to first-team training until the end of the following March.^[15] Although he regained sufficient fitness to help Birmingham's U23 team beat Sheffield United U23 in the national final of the 2020–21 Professional Development League,^[16] he had no matchday involvement with the first team in what remained of the season.^[17]

In June 2021, reassured as to his future by manager Lee Bowyer and director of football Craig Gardner, Boyd-Munce signed a two-year contract to remain with Birmingham City.^[18] However, he had no further involvement with the first-team matchday squad, and Bowyer suggested he was likely to be leaving.^[17][19]

Middlesbrough

On 7 January 2022, Boyd-Munce signed a two-and-a-half-year contract with another Championship club, Middlesbrough, for an undisclosed fee.^[20] He started the next day's FA Cup third-round tie away to League Two club Mansfield Town, scored his side's second goal after 14 minutes of a 3–2 victory and, according to the TeessideLive reporter, made a positive contribution both in and out of possession in the hour he spent on the pitch.^[21] He made only two Championship appearances over the next 12 months, both as a substitute, and his contract was terminated by mutual consent at the end of the January 2023 transfer window.^[22]

St Mirren

Boyd-Munce signed a short-term contract with Scottish Premiership club St Mirren in March 2023.^[23]
