job send email to developers upon complexion and include DBAs if it fails
What you can do is, add a job step called for example mail dba.

In that job step you put the msdb.dbo.sp_send_dbmail 

An example job step

EXEC msdb.dbo.sp_send_dbmail  
    @profile_name = 'DBA',  
    @recipients = 'some_email@somedomain.com',  
    @body = 'The Job Failed.',  
    @subject = 'Automated Error Message' ; 


Then you edit every step of the job to go to job step mail dba when it fails.
