And sometimes you are hiring construction workers, and sometimes trade-specialists. I've hired contractors to address specific tech-debt, or accelerate QA on project, to implement a CRUD type stuff for things with well-known approaches that just take time.
Well, then may be it's important to note that we are talking about two different industry niches and practices from one of them are not a good match for the other. And may be we even should come up with some kind of names for these kinds of "tech" to avoid mixing one up with the other.
We do have a variety of words that have certain connotations -- there are even essays / blog posts about the supposed hierarchy (or soup) of script kiddies, hackers, coders, programmers, developers, architects, etc. etc. etc. but the analogies to their metaphorical ancestors (very often from real construction) are neither perfect nor stable. A housing developer can more easily search for laborers than a software hiring manager can search for a code monkey who doesn't try to steer the ship!
