The former Platform Home Loans boss will be responsible for shaping the strategy and plans of the software provider.
Tweedy said: "This is an exciting move for me to an ambitious and expanding business. I’m looking forward to re-joining the UK financial services market at a key time and helping to shape Target’s business growth over the coming years.”
Target’s chief executive Paddy Byrne added: “I’m delighted to welcome David on board, his wealth of highly relevant market experience and strategic approach will help drive our business growth forward. He will provide valuable input to support our customers and the further development of our business.”
Tweedy has a 25-year career in residential and commercial mortgages and retail banking, with a strong track record in mortgage funding, originations, servicing and leading change.
For the past year he has been working in Dublin for Ulster Bank as head of mortgage arrears and prior to that he was the managing director of Platform Home Loans for 13 years.
He has also worked in a number of board level roles at Britannia Building Society, Western Mortgage Services, The Money Store and, during the 1990s, Lehman Brothers.
At Target David will be responsible for shaping our strategy and plans as the financial services market evolves. He will work closely with the sales and marketing team to monitor Target’s key markets and work with customers to understand trends and identify new opportunities.
