The scrapping of a total of 11 positions is part of a wider restructure at the publisher, which comes into effect from April 10.
In addition to the commercial director roles, the firm is also dropping the position of magazine trading manager and deputy magazine sales director.
At the same time, Emap has created two head of market positions, which it is looking to fill. They are: head of men's entertainment, which will oversee Q, Empire, Mojo, Kerrang! and Match; and head of women's weeklies, which will span Heat, Closer and the soon-to-be-launched Project Jackie.
Emap said it expected that, of those affected by the redundancies, some would be redeployed within the company, either taking on the new head of market positions, or roles in other areas of the business.
Marcus Rich, Emap Advertising's managing director, said: "All of the commercial directors at Emap Advertising have performed magnificently and made our magazine sales operation the fastest growing in the UK.
"We must, though, continue to respond to our customers' needs. These are greater access to decision-makers, quicker responses and more resource in growing areas of interactive and Emap. I believe these positive changes will meet those needs."
