It is thought Wildman will create two content divisions that consolidate commercial teams around a cluster of magazine brands.
The luxury and young women brands division, led by chief revenue officer Duncan Chater, includes Cosmopolitan and Elle.
The lifestyle and homes titles, led by Sharon Douglas, who is currently group publishing director of lifestyle, would comprise titles including Men’s Health and Runner’s World.
In a move to win over advertisers, it is expected that the commercial team will be organised in a number of hubs to cater for the big media-buying agency groups.
Hearst UK has committed to move to a new headquarters in Leicester Square next year but Wildman is keen to make the organisational changes now. These will include new divisions to run operations and devise strategy.
A Hearst spokesman said: "We are proposing a number of changes to both our editorial and commercial teams to ensure that our brands are in the best shape possible for the future and to allow us to develop more content in key areas where we see an opportunity for growth.
"As a result we do expect a number of people to leave the business, but we won’t know until the end of the consultation process what that number will be. Hearst UK prides itself on transparent communication coupled with a sensitive approach and we will ensure that everyone is supported with great care."
It is thought the process will complete by the end of July. Wildman took over from Anna Jones in April.
The publisher lost several dozen roles last autumn when it closed All About Soap in print and cut back two websites.
