Job Description

Description

The Multi-Domain Solutions Division at Leidos currently has an opening for a cleared Senior Systems Engineer .

That broader effort is known as Joint All-Domain Command and Control (JADC2). As envisioned, JADC2 will allow U.S. forces from all services — as well as allies and partners — to sense, make sense and act upon a vast of data and information faster than adversaries can detect and respond.

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.
