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.<h2></h2><h2></h2><h2>Original Posting:</h2>August 26, 2025<div><div><div><div><div><div><div>For U.S. Positions: While subject to change based on business needs, Leidos reasonably anticipates that this job requisition will remain open for at least 3 days with an anticipated close date of no earlier than 3 days after the original posting date as listed above.</div></div></div></div></div></div></div><div></div><h2>Pay Range:</h2>Pay Range $104,650.00 - $189,175.00The Leidos pay range for this job level is a general guideline only and not a guarantee of compensation or salary.
