"Front-end Developer" or "FE Engineer" are pretty standard titles these days. It essentially means you deal with the whole web stack (from Apache on up to CSS/JS) on servers that talk to a backend API. Your code typically won't deal with accessing databases directly or creating APIs.
Don't think of FE vs BE as HTML/CSS/JS vs server-side code. It is API client vs API server code. Architecturally, these stacks tend to be completely separate.
