What types of jobs/careers involve using Linux?  I'd like to hear from those of you who use Linux on the job, whether Linux is your main job/career or just one aspect of your job/career.

Although I am currently seeking an embedded engineering position (working with microcontrollers), I have also thought of turning Linux into a career as well.  An embedded engineering position at a workplace that uses Linux would be a good way to combine the two.
