    At Leidos, we don't want someone who "fits the mold"-we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, "what's next?" before the dust settles on "what's now."

    If you're already scheming step 20 while everyone else is still debating step 2... good. You'll fit right in.
