MS&E jobs in CO?

Hi there,
Recent M.S. graduate in MS&E trying to get a job in Colorado...Lockheed
Martin, although they have a perfect position for my background, won't bite
(and they seem to not like follow up calls), and I really would love to work
for them. But there must be other good companies out there. I'm interested
in any and all facets of MatSci, especially semiconductors and metallurgy.
Does anybody here know of some good, high tech materials science and
engineering-related companies in Colorado? Preferably in the Denver area,
but not necessary. I'm actually usually very adept at using web searches
for this kind of thing, but I'm having a hard time with this particular
subject.
Thanks in advance!
Matt
