What's the use case for them needing a subdomain of yours where they control the DNS though?

If you have the slightest doubt (the use of aggregators to get job postings sure sounds iffy to me) you're probably better off continuing your existing trajectory.

I like your site's premise btw; I've long thought the route to knock LinkedIn off their perch was via resumé curation as a first step.

Incidentally your cut&paste reply to every response here looks a bit spammy. Not really necessary IMO.
