We do hire interns but we don't have a regular (e.g. summer) internship program. Interns are hired when we have a space and usually stay until graduation. Right now we have interns so it's unlikely we'll have new intern positions until, at least, the end of this year. If you're interested I would sign up for USAjobs.gov and create a notification for engineering internship positions. You can see a list of our current open positions [1] on USAjobs.gov as well.
