Absolutely. I work currently doing QA as a large portion of my position (even though my title is GIS Analyst).

I write multiple testing scripts for our company's software tool that are immensely helpful and time-saving. No one else on our team has these kinds of scripting and automation skills and it can end up being frustrating. Many of the other GIS Analysts are surprised about what can be automated. I built a basic unit testing system for us that none of the programmers really had time to build. I'm basically going alone when I do these things.

I enjoy the scripting portion of my job more than the QA portion of my job by far. Perhaps the reason you don't find too many dedicated QA people who can write scripts is that, by and large, people who can script/code like doing that more than testing.
