The phrase "technology utility player" almost perfectly describes my current role. My official job title is "Principal Software Engineer". However, I spend less than half of my time doing actual software development. I am also responsible for maintaining the Linux side of our infrastructure (it is a mixed Windows/Linux environment and IT only manages the Windows side); occasionally get pressed into service debugging low-level hardware issues in prototypes of custom boards and cables; and until fairly recently was being shipped all over the country on short notice to support product demos.
TBH I actually enjoy this kind of role, except for one aspect: I don't think management understands that everything takes longer because I am juggling so many different things. All they really see is that Project X, which was supposed to take 80 hours, takes a month or more of calendar time. Or that infrastructure issue Y goes unresolved for weeks because it isn't an emergency (yet) and never floats to the top of the priority list.
There used to be two of us "utility player" software guys here. The other one quit a few months ago, and we were not able to find a replacement with the same mix of skills. This has definitely lengthened the list of things I need to juggle.
