Watson (pictured) will be based in London and report directly to Nick Hilton, head of lending.
She will be responsible for post completion administration as well as providing support and efficiency of process for all borrowers, from loan enquiry through to redemption.
Her previous roles include redemptions officer at Amicus Finance, as well as collections and litigations agent at The North View Group.
Guy Harrington, CEO of Glenhawk, said Watson had joined at an exciting time, as the lender continues to explore new ways to expand its business offering.
He added: “Following the launch of our free valuation offering initiative, the business continues to perform strongly.
“The significant redemption figure demonstrates the growing maturity of the business while being testament to the quality of both the loans the team is originating and the counterparties we are transacting with.
“At the same time, the amount of enquiries we are originating is growing month-on-month, highlighting the continued appeal of investing in UK real estate.”
Since launching in January 2018, Glenhawk has lent more than £50m, across 87 loans with a total gross asset value of £103m, and has originated over £750m of enquiries.
