About The Position

The Defense group at Leidos has a career opening for a Network Information Security Specialist on a DISA contract. This role is primarily on the customer site at Scott AFB, IL.

You’ll fit right in. Original Posting: January 13, 2026 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.

Additional factors considered in extending an offer include (but are not limited to) responsibilities of the job, education, experience, knowledge, skills, and abilities, as well as internal equity, alignment with market data, applicable bargaining agreement (if any), or other law.
