Amorim was hired at S.C. Salgueiros of his home city in July 2016.[1] On 6 October, he climbed up a level by being hired at C.D. Santa Clara of the LigaPro, when Quim Machado left after only two weeks.[3] Having won once in 11 games, he was replaced by Carlos Pinto two months later.[4]
On 18 January 2017, Amorim returned to the third tier at fourth-placed U.D. Leiria, signing an 18-month contract.[5] He won 15 and lost 3 games over the remainder of the season, although the club were placed in the relegation series.[6][7] By 8 October 2017, Leiria were the only team in Portugal's top three leagues to have won all their games (five in the league and two in the Taça de Portugal), as owner Alexander Tolstikov targeted a future place in European competitions.[6] The team however missed out on promotion after losing their playoff semi-final to C.D. Mafra on the away goals rule in May 2018.[8]
In June 2018, 41-year-old Amorim signed with F.C. Vizela and was tasked with winning promotion to the second tier.[9] His team fell in the playoff quarter-finals, again on the away goals rule, this time to U.D. Vilafranquense.[10]
Amorim returned to the Leiria District and signed for C.D. Fátima in 2019. He left by mutual consent on 21 November, with the club in 8th place after 11 games.[11]
On 26 January 2021, Amorim signed for Clube Condeixa for the remainder of the season.[12] He returned to Salgueiros for the following campaign. In April 2022, with his exit for disciplinary reasons not concluded, the team played their promotion series game away to Leça F.C. with no manager.[13]
