Hehe. On weekdays I go to a building that is owned by a company. I sit down on a chair at a desk, stare into a device and sometimes push some of the 105 buttons on it. Sometimes I also fill out forms on paper. After 8h plus break I leave and go home. In return the company advises my bank to increase a number each month.

We have really advanced technology, so few people have to work in agriculture or as handymen and theoretically it's enough to feed us all. The rest of us keeps busy by shuffling paper around. And in recent times we were able to do away with some of the paper and replace it with those machines. There are some slightly different variants, but they pretty much all look the same.

Well, my job showed up around then. So they would know the term Millwright, but the modernisation would probably make them a little incredulous.

My job is to digitize cassette tapes, VHS tapes, and other magnetic media.

So first I'd have to explain the miracle of how we managed to capture moving images and sounds onto these thin strips of plastic covered in rust. I'd follow that up by explaining how that technology is now considered quaint and out of date, and that these days we just get a thinking machine to remember that sort of thing for us.

I'm a glorified locksmith for magic wiz boxes. Technically I do other things as well, but mostly it's just getting past the locks that people have lost the key for.

There are also magical entities that take works from the nether realm and bring them into existence here, only they are all powered by grumpy demons and so I don't deal with those.

I'm a magister, scholar, and merchant. (I own a technology company).

Hmm... I'm a cosplayer/erotica model. So a seamstress that gets naked for money? Not too outlandish, but they'd never understand what cosplay was.

We have these things that are like stained glass books and I make how the glass looks.

Front-end developer.

I'm a teacher. They would understand that I educate the young, but would be nowhere close to understanding my students. They would think I teach a few children of the wealthy when I actually teach hundreds from the poorest of families in my area. Including several imigrants who speak a different language and many students with various disabilities.

Yes, my job has a fairly simple explanation. People who feel bad for whatever reason sit on my couch and I help them feel better.

Edit: I'm a therapist.

Anyone in the history of civilization would understand my job

Hell no

I test and design massive industrial electrical systems used in steel mills, power grid distribution, space equipment, coal mines, oil & gas, etc etc etc.

They didn't even figure out electricity at the time

I make a long list of things for people to do in order to create a final outcome, and then keep track of the progress and find solutions for deviations.

Project manager.

They never really called it that, but I'm pretty sure the concept isn't new. Architects and the likes did pretty much the same when building ginormous structures back in ancient Rome and Egypt, so they'd get the idea. Probably wouldn't understand the project deliverable, but at least the process.

I am paid to perform other duties as assigned.

If anyone has any idea on how to explain generative AI to someone from the 1700s, let me know. Maybe we can try explain my job then.

First I'd have to explain electricity. Then I'd have to explain electric circuits.... And the function of different components

THEN i could try to explain what my job was

We have devised methods to allow performers, both thespian and musician, to be heard and seen by larger and larger audiences. These audiences can be several thousand. Imagine if an entire city came out to see the performance.

I am one of the individuals responsible for maintaining and operating those tools.

I sell drugs and drug accessories, I doubt it would be hard to explain.

Lots of "I use magic to do magic stuff" for talking to people not long after the Salem witch trials.

Easily, I think they had a form of food delivery in the 1700's, it's just faster now.

Nope

I am a computational chemist so... Not sure how you would translate that so that someone from the 1700s would understand but whatever it is would get me burned as a witch.

I use vastly advanced looms to do math

Yes.

Before the melancholia debilitated me, I worked a long time as an unguilded teamster.

i sell gold & silver so ye

I put roofs on, both slate and standing seam. They would probably be surprised at how much money the really rich people have. But explaining standing seam would be pretty easy.

We even get our copper from Revere, as in Paul Revere, though he wasn't born until 1735.
