Hello swbluedevil, thanks for your question.
I agree that your GPA is slightly low, but I certainly think it is surmountable. Was there an extraordinary circumstance that caused your low marks? Did your GPA rise as you progressed through undergrad? If so, you might try to explain these factors in the optional essay. Better yet, it’s probably better to point an analogue that is a better representation of your academic ability and potential. In your case, your 4.0 in EE from UCLA would work well. Moreover, your 750 (assuming your quant score is over 80%) should mitigate potential concerns. Programs really just want to know that you can handle the material, and I think you have that evidence.
So, in short, you might address it in an optional essay, but I would simply say that your 3.15 undergrad GPA is not the best representation of your abilities and point to those other items that are better indicators. No need to have a defensive tone with the essay.
Otherwise, I think your competitiveness will come down to the quality of your leadership experience, both in and out of the office. Can you draw upon “moments” when you truly led: influenced individuals and organizations, drove results, took initiative? With your background, I would think you will have a solid selection of stories that demonstrate this.
Best of luck,
