Cheshire East Council has appointed Carole Mullineux to the newly created post of business development manager as it attempts to deliver extra attractions on the estate.
The council is facing strong local opposition from residents to certain plans including a children's storytelling theme park, called BeWILDerwood, planned to occupy 125 acres of woodland.
Mullineux will join the Tatton management team from Monday, reporting to Brendan Flanagan, Tatton Park and Cheshire East visitor economy manager.
Cheshire East Council said in a statement: "This role will be instrumental in delivering the Tatton Park Vision, the park's five-year plan to develop its visitor experiences and fully realise its full potential and will oversee the park's commercial and marketing activities."
Mullineux previously worked in marketing and business development positions with Royal & SunAlliance, Venture UK and the Co-operative Wholesale Society.
Flanagan said: "As part of the Tatton Vision we have realigned our structure and staff roles to help deliver the long-term benefit we seek. Carole's role is instrumental in developing our capacity to deliver these benefits and ensuring a sustainable financial future for this historic estate."
Mullineux added: "I am really looking forward to working with the rest of the team at Tatton, understanding what is important to our visitors and developing new and existing products and services to enable the Tatton brand to continue to flourish."
Tatton Park is managed and financed by Cheshire East Council on behalf of the National Trust. The 1,000-acre deer park attracts 750,000 visitors a year.
