Kind person like Vlad once a Guardian worker? (10)
I believe the answer is:
typesetter
'once a guardian worker?' is the definition.
(the Guardian newspaper once employed typesetters)
'kind person like vlad' is the wordplay.
'kind' becomes 'type' (type is a kind of kind).
'person like vlad' becomes 'setter' (Vlad is a Guardian crossword setter).
'type'+'setter'='TYPESETTER'
(Other definitions for typesetter that I've seen before include "whose work will leave a lasting impression?" , "Printing expert" , "Old newspaper producer" , "Former newspaper employee" , "Compositor" .)
