The 19-year-old joins on loan from Motherwell and follows Leighton McIntosh (Wrexham), Adam Livingstone (Motherwell) and Seb Ross (Aberdeen) to the Balmoral Stadium.
Cove boss Hartley told the club website: "I would like to thank Motherwell and their manager, Stephen Robinson, for giving us the opportunity to work with Jamie.
“He’s an exciting young player and joining us gives Jamie the opportunity to gain more experience of playing at first-team level, which will be great for him at this stage of his development.”
