When I made it to the phone screen, the interviewer asked if I'd seen the editor role, and if that would be of interest. So, at this point, I broadened my stance and said I'd love it if she could give me the details of both roles. We had an open dialogue about how much writing and editing I'd like to do; and in the end, I technically landed the editor role — but with a larger writing component than it had originally called for.

So, while I wouldn't suggest applying to multiple positions out of the gate, don't shy away from an honest discussion with the hiring manager. If he mentions that you might be more interested in or qualified for another role, that's your perfect opening to mention that it caught your eye as well.
It's awesome when the company you're interested in is hiring. But just because multiple positions catch your eye, doesn't mean you should put in an application for each one. Use the tips above to see if you can narrow your focus and submit a targeted application.
