Jessie worked as a school teacher at Saint Thomas, Ontario for some time and then studied social sciences at the McMaster University from where she graduated in 1947 with a Bachelor of Arts and decided to serve the cause of people in difficult circumstances overseas.
She came to India in 1947 and served as a Missionary in Kakinada, Vuyyuru, and Tuni. In 2009, the circle members comprising 10 ladies visited India to see the places where Jessie Rosser served, especially the Eva Rose York Bible Training and Technical School for Women in Tuni.
When Jessie Rosser came to India during 1947/1948, the members of the Centre Street Baptist Church in Saint Thomas, Ontario formed a Jessie Rosser Mission Circle in honour of her.
