What do you define as graduate-level maths courses? The scope and depth vary considerably. What I did in the first year of a maths degree may be (is, have seen) considered graduate level in some (some) engineering courses. Could you be more specific?

Great point! I'm thinking of analysis courses that begin with measure theory, also differential geometry and calculus on manifolds (though those definitely can be undergraduate). Some graduate level math-in-engineering topics are things like linear systems theory, convex analysis and optimization, nonlinear systems, etc.
