They might say dude or guy. I suppose they could have said "chick" but is that offensive? His statement was clearly that a fashion person was rather useless for a technology company.
Dude, guy, chick, woman etc, would I imagine be fine (there has to be some way of describing someone after all), but the term "female", while obviously accurate and not inherently offensive, strongly emphasises the fact that the word was chosen consciously to highlight gender, making gender an issue.
