The Queen is advertising for a washer-up, who must be willing to travel for up to three months of the year around her palaces to do the dishes.
The 86-year-old monarch is willing to pay £14,200 a year, which works out at £6.83 an hour, well below the London Living Wage of £8.55 an hour.
The General Catering Assistant (Wash-up) job is the latest in a succession of openings at the Palace to pay below the living-wage rate, following similar packages for a gardener and a butler.
Though based at Buckingham Palace, the role involves travel to Windsor, Sandringham, Balmoral and the Palace of Holyroodhouse in Edinburgh when the royal household moves around.
The job advert on the royal website states: "You must be willing to work away from London for up to three months of the year.
"You will join the team responsible for maintaining the cleanliness of the staff restaurant, wash-up areas and equipment in accordance with the Health and Hygiene Regulations to ensure the smooth operation of the staff restaurant."
The successful applicant must be "punctual, reliable, able to work well in a team and have a flexible and willing attitude".
The job - which is for 40 hours a week - has a closing date for applications of 15 January.
