Tyson previously spent seven years at Shawbrook Bank, initially as lending manager and senior lending manager positions.
He was promoted to team manager of residential mortgages in 2015, and in that role handled complex applications.
Since launch in May 2017, the bridging lender has been hiring quickly – with its team expanding from three to 17 in the period.
The specialist lender said it will shortly be announcing more senior hires.
Tyson commented: “I’ve always enjoyed challenging myself and there’s no better place to do that than at Octane Capital, which has ripped up the rule book with its product-less lending.
“I can’t wait to get stuck in and help the company achieve the impressive growth targets it has set itself in the years ahead.”
Matt Smith, director of risk, added: “The Octane risk team is quickly starting to form into the most impressive I’ve worked with.”
