Ohiaeriaku played for Osun Babes as their first-choice goalkeeper in the inaugural Nigeria Women Premier League, where the team finished in third place. This performance resulted in the teenager being called up to the national team.[1] She subsequently left to join reigning champions Rivers Angels after they won two subsequent league titles, before transferring back to Osun Babes in early 2016. In a statement, she thanked the team and the support staff at Rivers Angels, describing them as family.[2]
Later that year, she transferred to Swedish side IFK Ostersund on a one-year deal with a possible extension of a further year.[3]
In the run up to the 2016 FIFA U-20 Women's World Cup, she hoped her continued football in Sweden would help her achieve a place in the squad.[8] She was subsequently named in the squad for the tournament.[9]
