What is "the line"?
> Below the line (BTL) advertising is more one to one, and involves the distribution of pamphlets, handbills, stickers, promotions, brochures placed at point of sale, on the roads through banners and placards. It could also involve product demos and samplings at busy places like malls and market places or residential complexes.

Of course this definition is not exactly correct or exhaustive anymore, this is just the origin. Now it’s understood as defined by the other commentators.
As a terminology aside online retail sales still uses “hard lines” and “soft lines” as product & organization categories!
I would include that as above the line. My understanding is ATL is for mass viewing. While BTL directly or reasonably targeted to the individual. I say 'reasonably' as often EDM/DM (emails and mailers) have broad targeting cohorts & elements but are considered BTL.

Even with advertising alone there is 1) buying it, 2) concepting the brand message 3) writing the specific content 4) creating how it looks 5) creating the material and 6) Placing it 7) project managing the process 8) analysing the results - all as separate fields.
And within above people can specialise in specific categories like online, above the line (e.g. billboards), below the line offline (e.g. snail mail), TV, sponsorship etc
And that's just getting ads live....
I googled 'types of marketing jobs' and read about 5 articles and they all have different guides about what makes marketing roles and none seems to cover it.... One article put sales in marketing which is a common misunderstanding of what marketing is, and several times I've seen companies put top sales management in charge of marketing because 'they can sell' which does not work as its a surprising different skill set.
But here's a couple of articles to cover the common areas;
