Just to add some clout to this one, I'm doing consulting for WP Engine and @patio11 was here for a week in January. Jason, the CEO, is an amazing person to learn from, as he's already had one successful exit, and he builds a team that's the best of the best. We also have a great office space in downtown Austin and are flexible with remote workers.

Highly recommended that you look at applying here--even if you're from another country. (Especially if you're an awesome sysadmin who knows WordPress and lives in another country--we're actively looking for those right now.)
