Hi there, happy to help!

I think the demand of Mendix developers is quite high at the moment and will increase over the next years. For example, I am living in the Netherlands. Here there is way more demand than supply, which brings you as a Mendix engineer in a comfortable position. Moreover, Mendix is the leading low code platform (see Gartner documenten on mendix for example). With low-code in general, you are able to create business value fast and efficiently. There is growing demand for rapid development. Mendix supports this trend.

Also good to mention: I think Mendix is quite easy to learn. So it would not tak much time to understand and learn this technology :-).

Hope this helps!
