There is actually an old argument about whether Computer Science is math or science. The lack of hypotheses and physicality drives the "it's math" camp. I tend to fall into that camp. Most computer science is either math or applied math. That said, most of machine learning is not just engineering. If anything, there is little engineering done at all.
