much of science is based on engineering that made it work
Engineering is a form of applied science. This is why it is vital that engineers understand the laws of physics, and particularly the laws of Newtonian mechanics. You can't be an engineer without understanding how forces work.
In general, theory comes before application. Science comes before engineering. It's not the other way around, as you believe. Engineers don't just magically build stuff that works, and then invite scientists to have a look to work out how they did it. This is why, for example, no-one built a Tesla car in medieval times. Engineering is based on science.
science [...] doesn't work.
Scientific theories are falsifiable, yes, that's a fundamental strength that sets it apart from, say, religion. If the theory doesn't work in practice, that simply adds to our understanding, and helps scientists to devise new, better theories. If it does work, then it is reproducible, and anyone with sufficient expertise can verify this.
These are some of the reasons why some atheists hate religion. Religions are reasonably solid. And pure Bible religion is perfectly solid. Atheists hate religion because their atheism religion - which is often based on various science religions - offer no hope. The atheist knows he is going to die, and that without hope of resurrection. And his willfully ignorant enough that he won't go to the true, solid, Bible based, Christian religion, where he not only gets salvation, but the knowledge of it, as well. Self enragement against something he is willingly accepting as a good thing. Atheists don't make sense in their religion, atheism.
