Verilog and VHDL are the 2 languages for designing chips- Verilog is probably a bit more common.
Personally, I would recommend the verification field. There are surprisingly few people who can take a silicon design file and systematically and thoroughly test that it does what it is supposed to do in as many circumstances as practicality allows and be able to show that all the important areas have been covered through a logically valid system. It needs to be divided into a short set of tests that can validate a design change before it gets checked into the official copy of the design and tests that take all night to run.
Big field, actually. Verification people can be more in demand than designers. For some reason the universities haven't really pushed it as a field and thus a shortage of quality people.
