Kirk began her career at Leicester City, where she hails from, at the age of seven. She progressed through their academy ranks, and even earned herself international recognition during her time with the Foxes. This meant Kirk made a worthy claim to make her first-team debut for Leicester, and she did so in 2019, when she made her maiden appearance against Reading. After her first senior appearance, the forward was keen to claim more first-team minutes, and therefore joined Peterborough United in search of just that. And the 2022/23 season bore many fruits for the young striker, as she opened her first full senior campaign with plenty of strikes.
