Flight engineer? They've not had one of those for years! All of EK's current fleet only require a 2 man crew.
On longer flights, there may be 2 sets of crew.
I don't think there is any rule that says that there must be more than one person in the cockpit. I know some airlines mandate it - but I don't believe EK are one of them.
