Born in Lagos, Algarve, Viana spent six years as a youth at Sporting CP.

After two years with F.C. Penafiel in the second tier, Viana joined Gil Vicente F.C. of the top flight in 2013. In November that year, he signed a new contract to keep him there until 2016, and with a release clause of €5 million.
Viana signed with First Professional Football League club PFC Litex Lovech in June 2015, after two years in the Primeira Liga with Gil Vicente FC. In the summer of 2016 he joined PFC CSKA Sofia on a free transfer, after the former merged with the latter.
On 31 January 2017, Viana moved to C.F. Os Belenenses for an undisclosed fee. He scored once for the reorganised Belenenses SAD on 11 March 2019, as they came from behind to hold leaders S.L. Benfica to a 2–2 away draw.
After his deal expired, Viana was confirmed as a player for S.C. Braga on 25 June 2019, on a two-year contract.
