A couple suggestions:

1) You could use a gui (run X and vncserver so they can connect and have 
a desktop)

2) You could run something like Jupyter an have them connect to that.

Either method would allow them to connect via ssh as long as the 'job' 
is running.  I use both for different users/groups.
