After seven years playing for Rivers Angels in the Nigerian Women's Championship, in June 2015 it was announced Chukwunonye was joining the National Women's Soccer League side Washington Spirit. She was signed at the same time as Australian international Hayley Raso, with the announcement coming the day before the Nigeria women's national football team played Australia in the 2015 FIFA Women's World Cup. Chukwunonye said at the time, "I am excited to join the Washington Spirit family; it’s a thing of joy and a dream come true for me, I love playing with great players like Crystal Dunn, who I faced in the U20 World Cup in 2012. I am excited to work with coach Parsons because I know he will bring out the best in me." Chukwunonye was the second Nigerian international in the squad, joining Francisca Ordega. After playing two games for the team, she was released in December 2015.
