You can create default custom method in the same class. In the method return the hr.employee record id based on required conditions.
*Below Example from Default core Module:*
def _get_default_journal( self ):
return  self .env[ 'account.journal' ].search([( 'type' , '=' , 'general' )], limit = 1 ).id

journal_id = fields.Many2one( 'account.journal' , string = 'Journal' , required = True , default =_get_default_journal, domain =[( 'type' , '=' , 'general' )])

so in my case what should it put inside the domain ?  if i want to get the value of the parent_id field ?
def _get_default_manager(self):
return self.env['hr.employee'].search([('??', '=', '??')], limit=1).id

manager = fields.Many2one('hr.employee', string='Manager', required=True, default=_get_default_manager, domain=[('??', '=', '??')])
