Skills which someone has put a name to already are nouns. But if you are trying to say something meaningful about the skills required in a rapidly-evolving field, it is going to be hard to find prepackaged nouns and so you are going to need to use verb phrases.

EDIT: for example, the notion of a language “working” in a mechanical sense has only been around for the past 60 years. If there is a specific noun to refer to understanding those mechanics as you type, it is obscure. This 28-year old software engineer who has worked in both the US and UK has not heard it.

Skills are generally gerunds, which are nouned verbs. "Nouned" is an adjective made out of a verbed noun.
