Former Conservative cabinet minister Penny Mordaunt is taking up a part-time paid role with British American Tobacco as a member of its "transformation advisory board".
Details of the appointment were published on the website of Acoba, the watchdog that provides advice on jobs politicians accept after they leave government.
In a letter to Acoba, British American Tobacco said Mordaunt would be "asked to contribute her insights on the topics of tobacco harm reduction".
Mordaunt told the watchdog the role would also involve testing the company's strategy "to reduce its combustible products i.e. cigarettes".
British American Tobacco has produced some of the world's most famous cigarette brands including Lucky Strike and Rothmans, but in recent years has begun selling vapes.
The company says it wants to build "a smokeless world" by moving smokers to smokeless alternatives. It aims to become a "predominantly" smokeless business by 2035.
