Atkinson played youth football for Rush Athletic and the Metropolitan Girls' League Academy, before spending three years with Enniskerry FC. She signed for Women's National League (WNL) club Shelbourne in July 2017.[1]
The 2020 WNL season, delayed by the COVID-19 pandemic, began with Atkinson in excellent form for Shelbourne. Instead of occupying her usual position on the wing, she had been repurposed as an attacking left-back.[2] Her goal against Bohemians was named Goal of the Month for August 2020.[3]
Atkinson's first competitive appearance for Ireland was in a 1–0 FIFA Women's World Cup qualifying defeat in Norway in June 2018. She was an 89th-minute substitute for Áine O'Gorman and was shown the yellow card.[11] She started her first match in a 1–0 friendly defeat by Belgium, staged in Murcia, Spain, on 20 January 2019.[10]
