Gladman, who will report to Mark Escolme, Findus' UK Frozen managing director, was North America brand director for Ragu, Bertolli Pasta Sauce and Knorr at Unilever.
Her appointment to the newly created role comes as Findus looks to strengthen its presence in the UK and win over consumers yet to be convinced by frozen food.
Gladman joins on 6 September, and will work closely with Findus' group marketing, category and innovation teams.
She started her career in retail at John Lewis, before moving into the food sector with Mars.
