Use parameter expansion:

#! /bin/bash

strings=('Job with id 0 ended with status COMPLETED, return code 16, in 1 minute 12 seconds'
         'Job with id 0 COMPLETED with return code 255'
        )

for string in "${strings[@]}" ; do
    code=${string#*return code }
    code=${code%,*code%%[!0-9]*}
    echo $code
done

# removes pattern from the left, % from the right.
