Moving group to recruit egghead for role (13)

'moving' is the definition.
(repositioning is a kind of moving)

'group to recruit egghead for role' is the wordplay.
I cannot really see how this works, but
'egghead' could be 'e' (head letter of 'egg') and 'e' is located in the answer.
'role' could be 'position' (position is a kind of role) and 'position' is located in the answer.
'group' could be 'ring' (a ring is a criminal organisation) and 'ring' is present in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
