Furneaux-Harris joins NGN on September 1, when the newspapers will have been without a permanent chief marketer for almost a year. The post was left open when Nick Canning left in October to go to food chain Iceland.
He was replaced on an interim basis by promotions director Andy Agar, who quit in March to set up his own promotions agency.
Furneaux-Harris is a former Barclays and HSBC marketer. She left Barclays at the end of 2001 without a job to go to and has since been working as a marketing consultant. At HSBC, she handled the £22m marketing strategy of its rebranding from Midland Bank in the UK.
The Sun and the News of the World are the market leaders in their sectors and have undergone a series of editorial changes after David Yelland was promoted from his role as editor of The Sun to a vice-president of NGN-owner News Corporation.
News of the World editor Rebekah Wade took over at The Sun, and she was replaced on the Sunday tabloid by her deputy Andy Coulson.
There have been suggestions that the papers could get a new look following the appointment of Simon Cosyns as group art director.
The appointment of Furneaux-Harris as marketing director is expected to trigger a series of promotional activities, although it is expected she will be charged with keeping costs down following The Sun's expensive price-cutting war with the Daily Mirror at the beginning of the year.
