Excellent communication skills are required to interact with the customer and program team. This position is contingent on receipt of required clearance from the Government customer.
Required Clearance: Candidate selected will be subject to a Government Public Trust security investigation and must meet eligibility requirements for access to the customer’s information.

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.
