I’m actually a systems engineer for a major financial organization. My work’s been more on the hardware and Windows system administration side of the house than with tech writing, although I did have my eye on tech writing as a career path when I started in graduate school.
I enjoy being one of the few actual writers among engineers, as the old adage that “engineers don’t write” is certainly a truism. My writing skills will take me places in the future, but at present I’m making more money per year than I ever thought I would in my life, and I’m saving it for any eventuality such as the recent 6 month unemployment stint I was on before landing back on my feet here.
I'm with Heinlein on one thing at any rate: Specialization is for insects.
