Doctor abroad securing work for hippie (7)
I believe the answer is:
dropout
'hippie' is the definition.
(thesaurus)
'doctor abroad securing work' is the wordplay.
'doctor' becomes 'Dr' (synonyms).
'abroad' becomes 'out' (I've seen this before).
'securing' means one lot of letters goes inside another.
'work' becomes 'op' (common abbreviation for 'opus').
'dr'+'out'='drout'
'drout' enclosing 'op' is 'DROPOUT'.
'for' is the link.
(Other definitions for dropout that I've seen before include "Student who fails to complete a college course" , "A student no longer" , "One ceasing to participate in society" , "Cease to participate" , "Momentary loss of recorded signal" .)
