I can't help but notice that, with nothing in the way of demonstrable evidence, you are _presuming_ a female engineer to be incompetent and referring to her by her first name to boot. You're further implying that design is trivial work ("Okay, you can do the page layout, while we code"), subordinate to the real labor of coding. The general consensus I've surmised on HN is that design and UI are crucial for adoption; do you believe that Google's success was independent of the way that users used their product?
And if the public face of the world's most powerful search company has your imprint, isn't that _ipso facto_ evidence of merit? If design was in fact irrelevant, how could _any_ number of successful designs ever constitute evidence for the skill of the designer?
