Hill, the paper's former US business editor, replaces John Gapper, who is now chief business commentator and associate editor.
Hill said: 'There are two main areas where we might interact with PR professionals. The first is features, which used to be called Inside Track.
Andy Davis is in charge of that section and already fields ideas and pitches on the nitty-gritty of management, business, technology and science.
The second area is with PR people whose clients might be potential contributors.
We are looking to increase the variety of people who write for us and are interested in big names, experts in their field or possibly some executives who might have an angle on an area of business.'
Hill will also oversee the FT's comment and analysis pages, which aim to provide what the paper calls a 'global forum for opinion formers'.
He added: 'We are hoping there will be newsworthy names and pieces that become talking points in economics, policy and business. We are looking to make a big impact with the main analysis piece, which may be linked to a major news piece in the paper.'
He stressed that these pages were unlikely to be influenced by PROs.
Although Hill insisted that there was no need for 'radical change', FT editor Andrew Gowers said: 'The new analysis and op-ed pages are already among the best things in the FT, and Andrew will take their development to the next level.'
Hill joined the FT in 1998 and has held various posts, including foreign news editor, Brussels correspondent and Milan correspondent. Most recently, he spent four years as bureau chief and then US business editor in New York, where he was the main writer of corporate and business stories.
The FT has a daily circulation of 480,000. Internationally, it is published in 21 cities and has a global readership of 1.6 million people.
