During nearly four years, Juca gained six caps for Portugal. His first game was a 1–1 draw with Austria on 23 November 1952 in a friendly match in Porto, and his last appearance was in another exhibition game, with Hungary (9 June 1956 in Lisbon, same result).
Shortly after retiring, in 1960, Juca started managing, his first job being with main club Sporting's under-19. He was promoted to head coach of the first team the following year, being in charge for three 1/2 of the following five years, and winning the 1962 and 1966 leagues (he was only in charge for four matches in the latter campaign however) and the 1963 Portuguese Cup.
After spending the following years with three clubs, namely Académica de Coimbra – he was also inactive in some seasons – Juca returned to Sporting for the 1975–76 season, being fired after the team could only rank in fifth position, 12 points behind champions S.L. Benfica.
