I really do like “Alchemists” and though prefer it.
When I think about the mid-age alchemists, I do see very mystical people that are misunderstood by the mundane, because the knowledge they use seems like magic to the masses.
Sometimes there are people, that do treat me exactly like that. I do often encounter people, that consider building a spacecraft and flying to mars applied science, while programming (or even using) a computer is somewhere inbetween dark and light magic.
So I think alchemists is very suitable
