<p>That depends entirely on the job. Physics majors do get hired into engineering positions whether you find that incredible or not, so clearly some managers find them interchangeable. Further, in many (if not most) instances, having a graduate degree in engineering will completely supersede the physics undergraduate degree and put you on completely level footing. For some graduate tracks it is not even detrimental to not have that undergraduate physics degree, though if never call it an advantage.</p>
<p>That said, I’ve always been an advocate of the idea that if you know you want to do engineering, them get an engineering degree from the start. Not everyone knows that ahead of time, though.</p>
<p>The OP here, for example, is already to the point where he/she is getting a physics degree. It’s too late to change that. The fact is, then, that there are still options available and there is zero need to get an undergraduate engineering degree if a graduate degree is an option and something in which he/she is interested.</p>
