I don't recall if "artificer" was mentioned explicitly, but I was convinced in Patch 8 that
Barcus Wroot
was essentially representing that class. If you got him to join your camp and spoke with him, he described his occupation as something like that.

I haven't got that far yet in Patch 9, so I don't know if it's the same. It did make me wonder if artificer would be a playable class, or if he was a going to be a one-off for that.

Very curious if he will be able to join the party later...
