* Page and Esquire in the household of the Duke of Lancaster: This early role provided him with access to the royal court and exposure to high society.
* Controller of the King's Works: He was responsible for overseeing construction projects for the King, including palaces and castles.
* Clerk of the King's Works: This was a similar role to the previous one, with a focus on accounting and administration.
* Justice of the Peace for Kent: This position required him to adjudicate legal disputes and maintain law and order in the county.
* Member of Parliament: Chaucer served as a member of Parliament for Kent, representing the common people.
