A good data scientist should also be good at science. Otherwise, you can simply hire people with engineering skills - you don't need scientists. If you hire scientists and then are surprised they aren't good at engineering, the hiring process needs a reality check.

Statistics is a science as well. Unfortunately it’s overloaded in business terms and can mean anything from “knows means and regressions” to “has a copy of _Meyn and Tweedie_ on their shelf”.
