Brooklyn began his career with the Brazil Soccer School before being spotted by scouts from Premier League side AFC Bournemouth. He spent time on loan at Poole Town and was in Bournemouth's squad which went to Portugal for pre-season training in 2022. On 23 August 2022, Brooklyn made his first team debut for Bournemouth and scored his first senior goal after being on the pitch for one minute, during a 2–2 win on penalties over Norwich City in the League Cup.
