Industry sources said that Flint is the preferred candidate for the post, which will report to James Wildman, Yahoo's UK managing director and vice-president of sales.
Flint has worked at Virgin Media's sales operation, and its predecessor, ids, since 2009. Before that, he was the sales director at Hearst Digital UK.
A former colleague of Wildman's at ids, Flint is the front runner for a role that is due to be vacated by Steve Brown.
Last month, Marissa Mayer, the chief executive of Yahoo, announced plans to focus on mobile and improve the company’s search, news and e-mail services.
Flint and Yahoo! declined to comment.Follow @nickbatten2
