I did see their posts about the Eindhoven one and tried to apply to the relevant positions accordingly but some of the reqs that mentioned Julia explicitly got scrubbed very soon after I saw them.
I don't speak for the whole company, but in our project we are heavily Python based, Julia might be used by the central research team or something though.
Feel free to reach out to the email above, I think it's one of the most interesting jobs I could have gotten coming out of a postdoc due to the mix of physics and real world, technically interesting problem solving.
