this want-ad for an Executive Producer. We honestly thought that was a typo at first, but sure enough the "AAAA" designation is used no fewer than three times to describe the type of project Microsoft Studios will be constructing.
An executive producer's responsibilities sound pretty intense on a "AAAA" title, they've got to "deliver the end-to-end AAAA title experience" while they "maintain high-level relationships with external developers" and "represent and ensure that the project is aligned internally," all while traveling domestically and internationally.
That means that, basically, the only person qualified for this position is Commander Shepard. That works out though, because a fictional person is the perfect candidate to work on something as made up as an "AAAA" title.
