Run the process as a separate user.

Create a group, and add yourself and the user that the process is
running under to that group.

Make the directory under your home directory writeable by your group
(chmod g+rw /path/to/dir) 

Set the appropiate umask(2) or use chmod(2) to create the appropiate
permissions on the files.
