It said the "web content developers" didn't know JS, only HTML and CSS. I'm curious: What do "web content developers" do where they can get by without JS?
I recently finished a bunch of upgrades that parse DocX files, rips out the contents list, pre-fills the structure in the system, auto-imports all image assets and an extra utility that individually rips tables out of the DocX file and converts them to HTML. This was all to speed them up a bit.
On top of content entry you are required to do a lot of proof-reading and review work to make sure what you have entered is faithful to the document and generally correct.
My table parser still isn't perfect, its had a few documents thrown at it with merged cells that look just fine in Word, but don't have the colspan attributes I'm expecting.
Its still significantly reducing the workload of our content guy, he just has to double check how its displaying.
I've largely tried to avoid styling extraction but I did have a quick go, tables do contain properties for background colours and border tinting but the values don't seem to match what is being displayed within word. I think DocX has an equivalent of a stylesheet kicking around somewhere which may contain more accurate styling info but my work hasn't required that I look into it yet.
The other thing that may be needed in this position is actual content development skills, ie: writing. You could be responsible for doing blog posts, pages on websites, marketing copy, etc.
"Web content developer" would also be the lowest paid position in an agency typically. The salary ladder goes "web content|web maintenance/support" > "front-end|SEO|social/marketing" > "back-end|fullstack" > "management" > "ownership" in my experience.
