Hmm, how would one go about getting the required security clearance? That definitely would be an interesting position at those few buildings midway between the White House and Capitol Building, although I'm sure I wouldn't be cleared by the IRS, DOJ or FBI
...I will say that's one of the first postings for a BES engineer/administrator position that I've seen that accurately describes the qualifications required for the position. I'm not really sold on the application of an MCSE certification anywhere in the Microsoft administration world sans Active Directory administration (and even then...), but that's just my opinion (I suppose it could be used as a replacement for education requirements, but experience should shine over all of them).
