Generally, no, employers don't care. When you list your degree just list the graduation date.
Regardless of your work history, you should list internships and projects you accomplished while in school on your resume when you are starting out anyway (unless you were already employed in the field). And if anyone asks specifically, tell them, yea I took a little extra time to finish my degree. Never lie and don't deny it just be straight about it but don't go into personal details.
When you are in college all the pressure and focus is around your GPA, graduating whether you were in the engineering school or A&S school etc. When hiring, those factors are never as important as your ability to sell yourself. For companies that focus on your GPA or how long it took you to get through school, I'd be very critical of whether they are looking for the right candidates and whether I'd want to be there. That said, there are some tech companies that have extremely competitive new grad hiring and so they use school, GPA and degree as a filter, but I've never seen length of time to attain the degree a factor.
Good luck!
