If they thought "brogrammer" was all encompassing they would have not felt the need to clarify that women could apply too near the bottom of the post. The problem is not that they were trying to be overtly sexist, it's that they didn't see it as being sexist(which is so often the case when one is in the position of privilege) Obviously new to the job posting scene, they are unaware of how this particular post would be interpreted by the EEOC, I would hate to see a brand new company have to face off with a govt. lawsuit before they even get off the ground.
