He joined Hearts from his local team Inverkeithing United, and played for Hearts in a 1922–23 Scottish Cup tie against Bo'ness. He was later loaned to East Fife, and played for them in the 1926–27 Scottish Cup final against Celtic.
Gilfillan moved to play in England with Portsmouth of the Football League in 1928. He was to go on to make 359 senior appearances with the south coast club, including playing for them in the 1929 and 1934 FA Cup Finals. In his nine seasons with the club he kept 107 clean sheets in 330 League matches.
He eventually left Portsmouth to play for Queens Park Rangers, where he made 21 League appearances, and he then had a short loan spell with Clapton Orient, although he did not play a league game for them.
Gilfillan played for Clapton Orient against his registered club Queens Park Rangers on Thursday 11 November 1937 in a First Round Division Three Southern section Cup game before 3 500 fans at Brisbane Road. Rangers winning 2-0. Orient had their two goalkeepers unavailable. Jacob Iceton on the injured list and Charlie Hillam feeling unwell and had to go home, so Gilfillan was given permission to play by Rangers management and the FA against his Rangers teammates. He went back to Rangers the next day. Source: Neilson N. Kaufman, honorary historian Leyton Orient FC.
