The National Trust is looking for a guide to work at the childhood homes of Paul McCartney and John Lennon.
The "once in a lifetime opportunity" has become available due to a long-serving member of staff retiring.
The Beatles composed and rehearsed many of their early hits at the houses in Liverpool.
The charity said it wanted someone with "accurate historical knowledge" to bring the "early years of two of the Beatles' story to life".
Paul McCartney lived at 20 Forthlin in Allerton from the age of 13 to 22 and about 100 Beatles songs were composed there.
Lennon lived at Mendips, a 1930s semi-detached house in Woolton, with his Aunt Mimi from the age of five to 22.
