Absolutely, I can see how that could be effective. The jobs may lean toward electrical experience. Power engineering is a subfield of electrical and may be relevant. I looked into it once for myself, seemed like a good fit.
Another field of tools that I'm looking at are the Geospatial ones. Being able to work with mapping software/data always felt like a good mix to me.
What tools are they teaching now?
I studied on like AMPL for linear/nonlin prog, ARENA for sims, Matlab for general but it's been a while.
yes, geospatial could be interesting. The tools depend on what the university / lecturer prefers, for me it was Julia for programming in math courses, JuMP.jl for optimization modeling, Python for ML courses.
Probably the most elegant math book I have ever seen is Probabilty theory a graduate course by Achim Klenke. A very nice exposition into the abstract, measure theoretic prob. thoery (but it assumes some prior knowledge).
