...the fact that she is not a programmer or engineer serves her well as a tech writer.
This phrase is very true. I said the very same thing to a class of students at UTSA last fall, and I find myself thinking it at the career fairs I've been to recently. Many job applicants hear "technical writer," or sees what NI does, and think "I'm not a programmer" or "I'm not an engineer." To these students, I say, good.
We need more non-engineers and non-programmers looking at our products: testing them, writing about them, and polishing them via documentation or other means. We need creative people with non-technical backgrounds to push back on the developers and say "This isn't designed well" or "If I can't understand it, how will a customer?" After all, just because we're a tech company, that doesn't mean all our customers are technology oriented. Engineers and programmers are trained a certain way, which doesn't always include ease of use or user-friendliness. That's (part of) our job. So in these cases, being a non-techie is very beneficial.
So we don't need, or sometimes even want, you to be tech-savvy when applying for the open technical writer positions we have (hint, hint). When we're interviewing or looking at resumes, what we are looking for is that you are interested in technology or are curious or passionate about it. We don't need you to come in and start writing C++ immediately - that's for the programmers.
We do, however, expect you to come in and start writing English immediately :-)
