A BS+MS in four years, congratulations,you're already ahead of the game. A second masters wouldn't hurt,especially if you have an interest in a multidisciplinary field where you can use both degrees (robotics, biotech, space). Is there a reason why you don't want to start your career in EE at this time? Depending on your program, a EE MS on its own might be strong enough to get a job doing somethig you really enjoy. So what is it that you enjoy doing?

The previous NASA administrator, Mike Griffin, managed to collect 7 masters degrees along his career, so if you just like to learn stuff and earn recognition for it, it's possible to do so while working as well.
