Born in Rufisque, N'Doye began his career with Yakaar before moving to France to play for Épinal. Following his time there, he had stints at Créteil and Angers.[2][3]
On 14 July 2017, N'Doye signed a two-year contract with English club Birmingham City, moving on a free transfer.[5] He went straight into the starting eleven for the opening fixture of the 2017–18 season, which Birmingham lost 1–0 away to Ipswich Town,[6] and made 37 league appearances as his team narrowly avoided relegation from the Championship.[3][7] N'Doye appeared in Birmingham's first two matches of 2018–19, but with the club under pressure to reduce expenditure to comply with Financial Fair Play regulations, he was allowed to return to his former club, Angers, on loan for the season.[8] He was released by Birmingham when his contract expired in June 2019.[9]
On 6 October 2020, after over a year without a club, N'Doye returned to France, signing a one-year deal with Championnat National side Red Star.[10]
