A previous feature request has come up for attention by the development team. The idea is that "softwareengineering.stackexchange.com" can be quite long and annoying in the cases where people have to type it into their browser.
The development team is offering a shorter subdomain for redirect, however "se" as a subdomain is off the table since the abbreviation "SE" is also used for the Stack Exchange network as a whole.
A few possible options are swe, swen, or sweng. Another option, of course, is that a shorter subdomain doesn't make sense (either in general or because se is off the table).
