I'd vote in favor of removing gendered language altogether. The descriptions listed are vague and kind of meaningless.

For example, in the "masculine" company description, the words "dominant" and "boasts" are just fluff. Plus, who cares if you "are determined to stand apart from the competition"? Isn't everyone? And the "feminine" description is so passive and unclear that it makes me think the company could be an engineering support group and not an actual engineering firm.

I would suggestion something like, "We are a leading engineering firm with clients including X, Y, and Z." It's short and to-the-point. This way, it is clear that the company is an engineering firm, and hopefully clients X, Y, and Z are illustrious enough that they speak to the firm's capability/status.
