Go here (Lockheed Martin)

and do a search using MS2 for the business unit and Maryland for the location. I used to work there and we had a number of folks working there who lived in York.
Also try Northrop Grumman's website and search on Electronic Systems in Baltimore. We currently have hundreds of openings (obviously not all for MEs).
There's lots of defense work in the Baltimore area right now. As long as you can get a security clearance, there's plenty of jobs.
Good luck!
