In science jobs? No, get a grip. You can't effectively communicate sufficiently-technical ideas without using some jargon. The reason for that jargon is so that instead of describing a concept every time, you have a single precise word which means that concept. Because science is not everyday life, a lot of these concepts get words that are either not used in everyday life, or which have different meanings to their everyday ones.
Almost all fields of science can be simplified and then explained to a lay person by someone who is good at communicating. But in so doing, there are crucial aspects that end up necessarily getting simplified out. That is fine - good even - when you're describing it to a schoolkid or in a news interview, but it is not fine when you're actually doing the work.
