June 25, 2026For 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. It's a better process: facilitating a continuous ATO through real-time monitoring and dashboards that provide single pane of glass visibility into control compliance, zero-trust built-in to system design from day one, continuous evidence that gives auditors real-time proof instead of point-in-time packages, and an ATO that program teams can inherit rather than pursue.
