What's a Coffee Engineer? Are you engineering coffee plants, or is that a euphemism for a barista? I've started seeing the word engineer get appended to a lot more job roles these past few years; Sales Engineer, Technical Support Engineer, etc.
Yeah lol. Sometimes called Espresso Machine Engineer. Basically, the people who provide commercial espresso machines (usually a roaster) offer the cafes (and offices etc) installation, service and repairs. The Coffee Engineer goes out and goes that work.
Medium and long term, you would likely go self employed and then the roasters contract work out to you.
Since they mention being on the road, I'm guessing repair/maintenance of coffee machines?
I know what you mean though - I remember a time when the coffee machine was broken with a sign on it saying "an engineer is on the way to fix it", which some of the chartered civil engineers in the office found mildly offensive!
