Margaret Jobling is set to join Birds Eye in the new year as marketing director following just over a year with Cadbury as one of its heads of marketing.
Her departure follows that of former Cadbury marketing boss Phil Rumbol earlier this year.
Jobling replaces Ben Pearman, who has joined General Mills as marketing director for Europe, the Middle East and Africa.
Her first role at Birds Eye will be to continue the successful advertising run featuring the award-winning Polar Bear series, which claimed top spot in the TV and cinema category at this year's Gramia awards, run by The Grocer.
At Cadbury, Jobling was responsible for the Dairy Milk brand. She joined the company from Sara Lee where, as marketing director for household and body care for almost three years, she was responsible for a portfolio that included Radox, Ambi Pur and Brylcreem.
Jobling spent the majority of her formative career at Unilever in a variety of research and development, innovation and brand management positions, culminating in the role of male grooming global brand director.
There has been an exodus of senior management at Cadbury following its takeover by Kraft, with more than 120 senior staff out of 165 thought to have left the business.
