Science is a process by which the inner truth of the universe at large are uncovered. It is completely unconcerned whether the answers learned have any utility or not, science only cares about what is true and how can that be proven. Science asks questions and seeks to answer them by providing verifiable evidence one way or another.
Enginnering is concerned by what works and can be shaped into something useful. It doesn’t seek to answer any deeper truths about the world at large, it takes what is known to be true and seeks to improve it to achieve a utilitarian goal.
Science is of course of great help to engineering and it requires a lot of engineering to get proper science done, but both fields are quite distinct with very little overlap in what their goals are
